What is the relaxing phase of the cardiac cycle?
The resting phace of the cardiac cycle is known as the refractory period
What is a complete cycle of a heart contraction and relaxation called?
Cardiac cycle, which is made up of atrial and ventricular systole and diastole.
What is cardiac filling called?
diastole
Which phase of the cardiac cycle is longest?
ventricular diastole
At rest each complete cardiac cycle lasts about 0.8 secs of which diastole lasts seconds and systole lasts seconds?
0.5; 0.3
What part of the cardiac cycle is associated with the QRS complex?
The cardiac cycle refers to a complete heartbeat, including the systole and diastole. The QRS complex occurs during the depolarization of the right and left ventricles of the human heart.
What is the alternating relaxation and contraction of the heart called?
Diastole is the relaxation phase. Systole is the contraction phase. If you put these phases together you have the Cardiac Cycle...
What are the phases of the cardiac cycle?
Mid-to-late diastole, ventricular systole and early diastole
The stage of the cardiac cycle that directly follows the resting period?
Diastole
What phase of the cardiac cycle is longest?
Atria Diastole is the longest (0.7sec)
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
During what phase of cardiac cycle are all four chambers in diastole?
Once the ventricles contraction phase is over, the diastole starts. Then all the four chambers are in diastole, till the atria start to contract.
