High heart rate can increases risk of heart attack & cardiac arrest.
A cardiac cycle typically lasts about 0.8 seconds in a resting adult, but this duration can vary based on heart rate and individual health. The cycle consists of two main phases: diastole, when the heart relaxes and fills with blood, and systole, when the heart contracts to pump blood out. During exercise or increased physical activity, the cardiac cycle may shorten as the heart rate increases.
Cardiac cycle, which is made up of atrial and ventricular systole and diastole.
cardiac cycle
The heart contracts and relaxes during a 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.

Cardiac Cycle
The first part of the cardiac cycle is called diastole, which is when the heart relaxes and fills with blood. This is followed by systole, when the heart contracts to pump blood out to the body.
Cardiac tissue is the heart muscle and its function is to pump blood between the heart-lungs cycle and the heart-body cycle.
Phonocardiogram
In the cardiac cycle, blood flowing into the heart is called the systole.
