What does an average cardiac cycle take in seconds?
the cardiac cycle includes all events associated with the blood flow throught the heart during one complete heartbeat, that is, atrial systole and diastole followed by ventricular systole and diastole. the lenght of of the cardiac cycle is about 0.8 s, with atrial systole accounting for 0.1 s adn ventricular systole 0.3 s. the remaining 0.4 s is a period of total heart relaxation, assuming the average heart beats 75 times each minute.
Does the length of cardiac cycle decrease with more rapid heart rate?
The diastolic phase
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.
When do the AV valve close during the cardiac cycle?
AV valves close during the systole phase of the cardiac cycle.
Which is the phase of cardiac cycle in which the auricles contract?
The auricles will contract during the systolic phase of the cardiac cycle. This is one of the numbers that is measured when a patient has their blood pressure taken.
What is the duration of the cardiac cycle?
It depends on the heart rate. You take 72 beats per minute. Then the duration of one beat is 75 per minute. Then each beat will take 0.8 second to complete. This is taken duration of the cardiac cycle. You take 100 beats per minute. Then each beat will take 0.6 second to complete. This duration will be the duration of the cardiac cycle.

What mean of cardiac cycle?
the opening and clsoing of valves that creates two beats
The length of the normal cardiac cycle?
0.8 seconds
What is the graph detecting the electrical changes in the heart as it beats?
An electrocardiogram is a graphical recording of the cardiac cycle produced by an electrocardiograph monitoring heart beats.
Does the length of cardiac cycle decrease with more rapid heart rate?
The diastolic phase
When the heart is beating at a rate of 75 times per minute the duration of one cardiac cycle is?
.8 seconds
What is one complete heartbeat called?
The cardiac cycle.
What is the importance of cardiac cycle?
The importance of cardiac cycle is to sustain human life.
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.
How does the rhythm of the heart can be changed?
The rhythmic beating of the heart is maintained by the Sinoatrial node (80-100 beats/minute), the Atrioventricular node (40-60 beats/minute) or the Purkinje fibers (20-40 beats/minute). It involves the membrane potential of specialized myocardial cells in these parts. Once regions of the heart are fully depolarized (such as the ventricles), contraction follows. Immediately following depolarization comes repolarization, and thus the cycle can repeat itself.
When do the AV valve close during the cardiac cycle?
AV valves close during the systole phase of the cardiac cycle.
