Sinus Tachycardia

Question: is it normal to have a sinus tachycardia? i am diagnosed with sinus tachycardia and i am really confused about it is it normal.sometimes i have a chest pain and i am always nervous and my heart beat so fast it's just like i'm climbing into a mountain.

Answer: The definition of tachycardia varies, but most would take a heart rate of >100 as definitely tachycardic. Sinus rhythm simply means a normal heart rhythm, whereby each atrial contraction is followed by ventricular contraction. Sinus tachycardia is normal rhythm that is tachycardic (ie. a normal rhythm with a fast heart rate). It is not normal to have tachycardia when one is just sitting down at rest, or sleeping. It is quite normal to have tachycardia when playing sports, running, or doing any strenuous activity. So it depends on the situation - if you are experiencing tachycardia at rest, then more investigation would probably be warranted.

Question: Is inappropriate sinus tachycardia dangerous? i have had inappropriate sinus tachycardia for 2 years now. i take metroprolol 50mg 2 times a day and verapamil 60mg 2 times a day and i have also had 2 ablations done on me, but my problem keeps coming back. I wear a heart rate watch during the day. My cardiologist always has to adjust dosages or change the heart medicine. At what heart rate should i be concerned with to go to the er?

Answer: I don't want to ask you, were you checked for such and such because you were clear about having everything that can cause Tachycardia checked. I hope that you are not drinking too much coffee, tea or alcoholic beverages. You can also take a look at my previous replies to your questions if you have not already done so. This also can be a condition called postural orthostatic Tachycardia syndrome which is usually associated with chronic fatigue. Have you had an Echocardiogram? Ever seen a cardiologist for this tachyacrdia? There is an arrythmia called sinus node re-entry Tachycardia that can look exactly like sinus Tachycardia. There are medications that can slow the heart rate and not affect the blood pressure like Digoxin and amiodarone. Tachycardia on the long run can cause cardiomyapthy but this is more related to ectopic atrial Tachycardia and ventricular Tachycardia and not sinus Tachycardia. At this point, if you have not seen a cardiologist specialized in arrhytmias, my advice is to do so and have a specialized study called electrophysiologic study (e. p. s.) to see whether this is truly sinus Tachycardia or if it is another supraventricular Arrhythmia disguising as sinus Tachycardia. you can check out this site for more information http://heartscan.blogspot.com/

Question: How can you tell the difference between sinus tachycardia and a superventricular tachycardia on a 3-lead? I have been wondering what the difference would be on a rhythm strip. I know how it is different in theory but what differences would there be on an electrocardiogram?

Answer: The difference between sinus tach. & SVT is the rate. Sinus tach. is a sinus rhythm between 100 & 160 bpm (150 for some of the old-schoolers). SupRAventricular tachycardia is an excessively tachy. rhythm that originates above the ventricles.

Question: What is the difference between sinus tachycardia and atrial tachycardia? in the EKG strip?

Answer: basic concept: QRS complex: represent the heart electricity during ventricular depolarization T wave: represent the heart electricity during ventricular repolarization anything before the QRS: represent atrial electrical activity if what is before the QRS is a normal looking p wave then the signal originate from the atrial sinus. sinus tachycardia means that the fast rate comes from the sinus node, and so the signal s essentially norrmal except in that it is rapid. so on ekg it will appear as a normal wave ( with normal p) but only fast. Atrial tachycardia means that the rate is coming from the anywhere in the atrium ( which means that sinus tachycardia is a subtype of it). but for non sinus atrial tachycardia, they are of two types, Atrial flutter: the rate is all coming from one pacemaker, but it is too fast for the ventricles to respond, and this pacemaker is not at the sinus node, so instead of the P wave you will find a lot of similar but abnormal looking waves in between the QRS complexs, just like a saw tooth Atrial fibrillation: the rate is coming from alot of pacemakers in the atium and thus instead of any regular looking wave the p wave will be replaced by an irregular line ( but the QRS complex and t waves are still there, ofcourse)

Question: I have inappropriate sinus tachycardia I would like to hear from others what symptoms they have.? I have had this problem for 10 years. I have had ablation surgery and it helped for about 2 1/2 years and then it was back almost as bad as it was to start with. I have to take a lot of heart medicine to keep it under control now which makes my blood pressure to low. Does anyone else have this problem and how do you deal with it. Does stress make it worse for you?

Answer: "inappropriate"??? is tachycardia ever appropriate? follow up with your cardiologist.

Question: What causes chronic sinus tachycardia? Also experience anxiety and panic attacks. Could I have MVP? Also have anxiety and panic attacks. Do not have poor diet or sedentary lifestyle.

Answer: PLEASE DO NOT LISTEN TO VK!!! I Have tachycardia and have had to deal with it since 1997, at least that is when it was diagnosed,and it has to do with your sinus node , your hearts electrical system. It is usually treated with beta blockers that have to be taken daily to slow and strengthen the heart. If the problem continues, then there is a procedure called cardiac ablation that will "burn" all of your bad electrical path ways and usually your cured!!

Question: What can help me get rid of Sinus Tachycardia? It's a disease that makes your heart beat very fast!! Sometimes i pass out and sometimes i dont i have been having it for arounld 3-4 years and i want to get rid of it if you have anything simmilar PLEASE!!! Answer me!! I need all the HELP!! THANKS! "peace; love, and haromony"

Answer: I'm sorry I don't know...stay away from substance abuse it would be especially dangerous to you.

Question: If I have sinus tachycardia is it safe to exercise? My resting heart rate is usually between 90-150... so my question is it really safe to exercise? My Cardiologist says I will know when to stop, but I don't want to cause any problems...

Answer: I would listen to my cardiologist. If you are taking ANY statin drugs that is reducing your cholesterol output from your liver, I would be VERY concerned about the thinning of the arterial walls. This can lead to a stroke and any strenuous exercise would not be good. If you are taking statin drugs, you need to get a high quality CoQ-Quinol, not the typical CoQ-10 junk sold in stores. The fully reduced form is about 20 times more potent and will actually support dying cells, unlike the typical CoQ-10 junk you buy in stores that will actually damage your DNA. I would also see a Certified Nutritional Therapist that can get you on a high quality diet and supplements. Doctors are not trained in nutrition and should be working in conjunction with nutritionists to give you the best chance at getting healthy. good luck to you

Question: Is ventricular tachycardia the same thing as sinus tachycardia?

Answer: No Sinus tach is a heart rate greater than 100 beats per minute that originates from the heart's "natural pacemaker"--the sino-atrial node. When you have a fever or exercise and your heart rate goes higher than 100--you are most likely in sinus tach. Ventricular tachycardia (VT) is a fast (>100) rhythm from the bottom chambers of the heart--it is a serious and often fatal anormal heart rhythm

Question: what is th difference between sinus tachycardia, ventricular tachyardia and supventricular tachyardia? I had a few skips that went into a very fast heart rate the other day and I am just wondering which would it could have been and how do they tell which one. I went to ER everything checked out OK

Answer: Sinus tach comes from the SA node in the heart, the normal "pace-maker" of the heart. Ventricular tach is a rapid heart rate that originates in one or both of the ventricles and often doesn't produce a pulse. Supra-ventricular tach is a rapid heart rate that originates anywhere above the ventricles. Without seeing the rhythm on a heart monitor, it's impossible to say which you had. Don't rely on the ER for a problem such as this. They're designed for emergencies, putting band-aids on and telling you to see your doctor, etc. Make an appointment with a cardiologist who can order tests, procedures, etc. to determine the cause and then treat it. Good luck... Add: To "the doctor" -- WHAT!?! Sinus = the nose area??? You're full of it, buddy. Where did you get your degree? Never mind, I can tell you don't have one...

Question: Sinus Tachycardia? Have had sinus tachycardia for 3 years now and medication only helps a little. Doc suggested surgery. Has anyone had a successful surgery for this condition?

Answer: no, they will never cardiovert you with sinus tachycardia. it would kill you. that is only used in v-tach and other near death rhythms. I need to know how fast your heart rate is. and salt could do more damage. salt is for low blood pressure. though it is possible you are compensating, but there are certain tests for that.also you might need 2 take 2 meds together. are you over weight? look at your lifestyle

Question: ECG results - sinus tachycardia and possible right atrial hypertrophy? What does it mean? My resting heart rate hovers around 120bpm but I'm not having any symptoms, but now I'm starting to get worried! My doc wants me to have an echocardiogram and see a cardiologist. What are they looking for? I had thought I wouldn't be at risk for heart problems because I'm a healthy 21yr old. What could be causing this? Should I be worried? Thanks for your help.

Answer: Think of it this way, your Heart is a well oil machine that must work in sync, "If" one area or chamber is deficient the others will accommodate it accordingly. On the upper part of your Right Atrium and enbedded in the Mediastinal wall....is your SA Node (Your Hearts pacemaker) and should that atrium become damaged in any way, it CAN change the rhythm of your heart, I am NOT saying this is your problem. It is a possibility though!! The Sinus Node (SA Node) then follows down to the AV Node (Atreo-Ventricular Node) and on to the Hiss Perkengie Fibers that surround your heart and brings electrical stimulas. If the SA Node delivers a slightly faster Initiation, all other areas will respond accordingly. Having said this, your appointment to see a Cardiologist is appropriate and needful, because other situations CAN occur secondarily to this particular situation. Just a NOTE here.....age has nothing to do with it and never will, because we have been created with fallable bodies. The need here is to "Inspect" the Rhythm situation and possible cause, hope fully it will be something "Mechanical". ALSO......with right Atrial Hypertrophy (Being sort of baggy-saggy) your SA Node will endeavor to compensate for this condition.....increased Heart Rate. Having said that....the other parts of your Heart will follow suit as well. Everything is designed to do so.

Question: Sinus tachycardia and exercise? My heart rate has gone up to 120 bpm, but that has only been a couple of times. I am 29, a smoker, and have been pretty inactive for the past year and a half. While I was in shape, I didn't have this problem. Do you think that exercise is okay, and that it will alleviate the problem? My resting heart rate averages about 80-90 bpm.

Answer: Resting heart rate up to 80 is normal,90 a bit higher side. If u r a smoker this may be the cause than cut down tabacco. If it is simple sinus tachycardia occassionaly, u cud start exercise with gradual increase in time & intensity. If needed get an cardiologist opinion & ECG examination before starting. But it is must to be active physically for fitness.

Question: Sinus Tachycardia and anxiety? I spoke with my GP this afternoon having been experiencing rapid heart rate for a few weeks now and now am getting palpitations. He told me that it is anxiety related. I have had dozens and dozens of blood tests and all levels were normal, I even had blood tests done in A & E two days ago which were related to heart conditions and I was told they were normal. However, I take beta blockers at the moment but they make the palpitations worse, the GP says it's anxiety. But, can anxiety cause on-going sinus tachycardia? It seems that as soon as the beta blocker wears off the heart rate is up again! I was perfectly healthy until recently. I do have anxiety, but sometimes the rate goes up when I'm relaxed, and I feel it pounding. If it is anxiety related is the tachy constant or on and off? Does it cause the on-going sinus tachy? Or is it on and off? I'm very worried, I'm also getting skipped beats. What is Zoloft? I'm from UK Does that mean above 5 mins worth of episodes? And when the beta blocker wears off, if it is anxiety, surely if someone is relaxed their heart rate would remain steady? I'm confused. They can't find a physical cause for it, hence all the bloods being good. But, can weight loss cause it?

Answer: if your doctor's opinion is anxiety -then treat it.

Question: I know what inappropriate sinus tachycardia is. ? I wanted to hear from other people who have it to see how they deal with the symptoms they have. Stress makes mine worse. Does it effect anyone else this way? I haven't heard of anyone else that has this problem that I know personally That is why I am asking if anyone else has been diagnosed with this?

Answer: To the second writer, I thought the same thing until I researched it on line. IST has been recognized as a syndrome since 1979. I started working in CCU in 1983 and I have never heard of it until I researched this question. The patients HR increases rapidly with minimal exertion. They have symptoms of palpitations, fatique, exercise intolerance, orthostatic hypotension, blurred vision,SOB,tingling and sweatig

Question: WHY Sinus Tachycardia, Mobitz II and AF with fast VR are NEVER Caused by Digitalis?? Any sound explanation for this??

Answer: Digoxin suppresses the sinus node, mainly due to increased vagal activity. So only sinus bradycardia can occur, not tachycardia For the same reason AV nodal conduction is also slowed which causes ventricular rate to be slow in atrial fibrillation. Mobitz type II block is due to conduction problem below the bundle of His, in the bundle branches, where digoxin has no effect. Hence Mobitz type II block cannot occur with digoxin toxicity.
