heart 5.0 / 5 based on 1 rating ? OtherAAP002 session 10OtherNone Created by: niss81Created on: 01-09-20 06:18 the atrioventricular node (AV node): delays the electrical signal coming from the atria into the ventricles 1 of 21 the aorta receives blood from the: left ventricle 2 of 21 what is the term for the sequence of events that occur during one heart beat? cardiac cycle 3 of 21 most of the symptoms of acute left-sided heart failure are: respiratory in nature (e.g., dyspnea, orthopnea) 4 of 21 a vessel(s) that carry(ies) blood from the pulmonary capillaries to the left atrium is (are) the: pulmonary veins 5 of 21 which cavity first receives unoxygenated blood from the vena cava? right atrium 6 of 21 what term refers to the amount of blood pumped by the ventricle in one beat? stroke volume 7 of 21 what is the significance of elevated plasma levels of AST, CPK, and LDH? myocardial damage as in myocardial infraction 8 of 21 increased afterload (e.g., hypertension): increases the work of the heart 9 of 21 which term refers to a heart rate less than 60 beats/min? bradycardia 10 of 21 the right ventricle pumps blood to the: pulmonary artery 11 of 21 the purpose of the right heart is to pump blood: to the lungs for oxygen 12 of 21 sympathetic stimulation to the heart: increases heart rate 13 of 21 vagal stimulation on the heart: slows the heart rate 14 of 21 referring to the ECG, the QRS complex represents ventricular: depolarisation 15 of 21 decreased blood flow through the coronary arteries is most likely to cause: angina pectoris 16 of 21 ventricular systole refers to: contraction of the ventricular myocardium 17 of 21 an ejection fraction of 30% is: characteristic of a failing heart 18 of 21 what happens during ventricular diastole? the ventricles are filling with blood 19 of 21 where does the cardiac action potential (cardiac impulse) normally originate? SA node 20 of 21 heart rate and stroke volume determine: cardiac output 21 of 21
