If SA node (=natural pacemaker) fıring rate is 100 potentials per minute, but resting heart rate of a person is 75bpm, what accounts for the difference?

Can you please explain how to use this equation to get Flow(ml/min) Blood flow = π  ΔP r4 / ​8Lv

If you have a resting heart rate of 125 beats/min or bpm then you have: a normal heart rate, bradycardia, or tachycardia

In a standard EPS, briefly explain what is the difference between “pacing after sensing” and “fixed pacing”; in the study of inducibility to ventricular tachycardia (VT)?

Answer with A, B, C, D

In the following graphs of pacemaker potential recordings from the SA node, what graph represents what (ie parasympathetic nerve effect)

If a subject has stroke volume of 100 and heart rate of 53 bpm, What is his cardiac output in ml/min?

In resting state: For a heart that would have a left ventricle of 130 mL of end diastolic volume (EDV) and 60 mL of end systolic volume (ESV) and a heart rate 60 bpm. A. Calculate the output your pump should provide to the aortic arch. (in units of L/min) B. In moderate activity state: If the heart rate is expected to increase by 15% Calculate the output your pump should provide to the aortic arch hibernation levels so they can go back to sleep. A mitochondria-rich tissue called "brown fat" is responsible for this heat-generation.

Occasionally an ectopic pacemaker will develop in part of the conducting system of the heart. What happens to heart rate if an ectopic pacemaker depolarizes at a rate of 120 times per minute?
