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 else can I help you with?
Term for the blood pumped in a single contraction?
Cardiac volume is the blood pumped in a single contraction
What is the term for the amount of blood pumped in a single contraction?
Cardiac Volume
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
What happens during the T wave of the cardiac cycle?
During the T wave of the cardiac cycle, the ventricles of the heart repolarize, meaning they reset their electrical charge in preparation for the next heartbeat. This phase represents the relaxation and recovery of the heart muscle after contraction.
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
What is the name given to contraction phase of the cardiac cycle?
The contraction phase of the cardiac cycle is called systole. This is when the heart muscle contracts to pump blood out of the heart and into the circulatory system.
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.
The R wave of the ECG is most closely associated with which phase of the cardiac contraction cycle?
The R wave of the ECG is most closely associated with the depolarization of the ventricles during the cardiac contraction cycle, specifically with the QRS complex. This represents the initiation of ventricular contraction.
What muscles are straited?
smooth skeletal cardiac and contraction mbroro
Basic unit of contraction in skeletal and cardiac muscle?
The Sarcomere
