we measured the stroke volume of the left ventricle. What was the average stroke volume of the right ventricle at rest and after exercise?

What would be the fastest possible HR if the absolute refractory period for the cardiac myocyteswas 250 ms?

Calculate heart rate (BPM) with dimensional analysis. Heart is beating ever 1.13 seconds what would be the calculated heart rate per minute?

There are three major factors that affect stroke volume and therefore affect cardiac output: afterload, preload, and contractility. Explain how and why each of these factors affects cardiac output. Each answer must explain what the factor is as well as how it affects cardiac output.

Jack counted his lab partner's heartbeats as 13 beats in 15 seconds. What is the lab partner's heart rate? What other information would you like to have about Jack's lab partner to decide if this heart rate is abnormal?

Which of the following channels is responsible for generating the long plateau found in the action potentials of ventricular myocytes?   a-slow Na+ channels b-slow Ca2+ channels c-leaky Ca2+ channels d-leaky Na+ channels

What could it mean if the capillary refill time measures 2 seconds in the digits of one hand and 10 seconds in the digits of the other hand?

Consider the ventricular cardiomyocyte action potential shown below: a) Which phase of the cardiac myocyte action potential would be most significantly affected by the L-type calcium channel blocker nifedipine? b) Draw the predicted effects of nifedipine on the cardiac myocyte action potential.

What is the measured thickness of the left ventricle and the right ventricle walls?

a cardiac ultrasound patient is found to have a left ventricle stroke output of 98mL and a resting heart rate of 65bpm, what is the patients cardiac output?
