i did not understand your question well, but there are three wave in working heart i a second:
1-P wave:its about 0.1 second and contraction of the Atriums
2-QRS wave: its about 0.4 second and contraction of the bellies.
3-T wave:its about 0.5 second and relaxing of the heart..

What does the term systole mean?
Systole is the period of heart contraction within the cardiac cycle.
What ion is necessary for cardiac contraction to occur?
calcium is te most important ion in cardiac contraction , whereas the contraction starts by the Na .
Does cardiac electrical activity immediately precede the contraction of the cardiac muscle?
Yes
During which phase of the cardiac cycle do the ventricles relax and fill with blood?
diastole is when all 4 chambers of the heart are at rest after a cardiac cycle systole is the term used to describe the heart during a contraction
Each heart contraction begins in a small group of cardiac muscle cells called?
The sinoatrial node is the small group of cardiac muscles that initiates each heart contraction.
The R wave of the ECG is most closely associated with which phase of the cardiac contraction cycle?
Ventricular contraction.
What is automaticity of the heart?
The property that allows any cell in the cardiac muscle to begin an action potential, or a cardiac conduction, leading to cardiac contraction.
