Why is the normal resting heart rate actually slower than the natural pace of the SA node? Athletes routinely have elevated levels of PN activity at rest. Use this information to explain why these individuals have low heart rates combined with incre...
Why is the 'Pacemaker' potential of the atrioventricular (AV) and sinoatrial (SA) node cardiomyocytes unstable? Give another name for a pacemaker. What does a pacemaker do? Explain why the atria have thinner walls than the ventricles of the heart. What is the purpose o...

The sinoatrial (SA) node functions as a pacemaker of the heart and is found in the right atrium. It is a mass of tissue that generates electrical impulses 60-100 times per minute. It is the primary controller of the res...
Why is the pulse rate take several minutes to return to normal after a vigorous activity? Why is the normal resting heart rate actually slower than the natural pace of the SA node? What two effects does sympathetic stimulation have on the heart during exercise?

Why is the 'Pacemaker' potential of the atrioventricular (AV) and sinoatrial (SA) node cardiomyocytes unstable? In normal sinus rhythm, what does the P-wave, the PR interval, QRS complex, and QT interval reflect? 1.)Pulse rate while lying down: a.) Why does it change...
Why is the 'Pacemaker' potential of the atrioventricular (AV) and sinoatrial (SA) node cardiomyocytes unstable? What is the function of the septum separating the left and the right ventricles? Assume that for one beat, the stroke volume of the left ventricle is greater than that of the righ...
