Introduction:
The cardiac cycle has two phases, including systole and diastole, which is detected in the form of a heartbeat. The systole is accompanied with a ‘lub’ sound and the diastole with a ‘dub’ sound. These sounds are generated when the valves between the heart’s chambers open and close as blood pass through them.
