Question
Chapter 19.5, Problem 7AYLO
Summary Introduction
To discuss:
The volume of blood typically found in each ventricle when it finished filling, the volume ejected by the ventricular contraction, the percentage of blood that is ejected and the blood remains after contraction. The names of the four variables.
Introduction:
Cardiac cycle is a rhythm that is termed by the duration of one heartbeat to the other beat. A typical heartbeat consists of two stages namely diastole and systole. Heart muscles to relax and its chambers to be filled with blood is termed as diastole, and this beat makes the “lub” sound. Heart muscle contraction is termed as systole, and it makes “dub sound.

["QRS complex", "T wave", "P wave" , "P-R interval", "QRS interval", "ST segment", "QT interval"
preload
afterload
contractility
is the amount of tension in ventricular myocardium immediately before it begins to contract. It is elevated in exercise because so much blood is
flowing into the chamber quickly. The chamber walls stretch, which encourages increased
is the pressure in the
aorta and pulmonary trunk. When it is high, the ventricles must work harder to eject blood.
The period of ventricular filling :
O phase 1 of pacemaker action potential
O phase 3 of contractile cell action potential
O systole
O diastole
