Right Ventricular Infarction

Question: Why people experience chest pain when they have left ventricular failure resulting from myocardial infraction Florita Santos, a middle-aged woman, is admitted to the coronary care unit with a diagnosis of left ventricular failure resulting from a myocardial infarction. Her history indicated that she was aroused in the middle of the night by severe chest pain. Her skin is pale and cold, and moist sounds are heard over the lower regions of both lungs. Explain how failure of the left ventricle might cause all three of these signs and symptoms (the ones in italics). Please help

Answer: the biggest muscle in the heart is the left ventrical. it is responcible for pumping oxygenated blood throughout the whole body. the blood enters the left atruim from the lungs via the pulmonary vein, the only vein in the whole body that carries oxygenated blood. with this being said, with left ventricular failure, blood will back up in the lungs causeing "CHF" or conjested heart failure. CHF in a patient is almost diagnostic of left ventricle failure or weakness. this will cause the moist breath sounds, frothy red sputum, or awakening in the middle of the night and the need for 2 or more pillows to sleep. as for the chest pain, chest pain can be caused by many things, being cardiac related, you must remember that the heart is a muscle with its own blood and oxygen supply. a micardial infarction is caused my lack of blood reaching a part of the heart starving it of oxygen cause the muscle to being to do die. now the pain most commonly discribed by heart attact (M.I) patients is left shoulder, jaw, arm or midsternal pain. and the common reason for this is simple when you thing of physiology. the vegus nerve, one of the largest nerves in the body, begins in the cerivcal spine, wraps around your left should, across the heart and down the body. furthermore; when the infarct, or dying tissue reaches a part of the heart where vegus receptor is it starves the nerve sending pain up towards the shoulder and is felt in one of the varies if not all of the places i described. so with all this, you have a weakened left side of the heart, blood can not be pumped throughout the body as it did pre-m.i, so the body reacts with pale or cyanotic limbs and becomes sweaty due to the poor circulation and sympathic responce.' hope this helps, let me know if you need anything else!

Question: How to assess Left Ventricular function? A patient sustained a myocardial infarction 2 days ago. The cardiologist wants to assess left ventricular function. What test should the nurse anticipate the cardiologist will order? a. bedside echocardiogram b. electrocardiogram c. myocardial perfusion scan d. holter monitor test My guess was a.........but maybe c..........but I'm really not sure. i can't find the answer in my notes or online and I'm not sure which it is. thanks in advance!

Answer: a. Echocardiograms can show 'live' flow dopplers to asses LV Function. with ejection fractions which can be measured against standards.
