Does diving affect the heart rate or the time interval betwe

Solution

As a result the volume of blood in the blood vessels of the chest and heart rate increases significantly resulting in stretching of the walls of heart and large vessels.

At 100 feet the pressure triples our heart rate beats lower which helps to conserve oxygen and allow us to dive deeper. it was noted that in divers heart rates as low as 14 beats per minute compare to the average heart rate of 60-100 Beats per minute.

Ill effects of diving during diving an acute Myocardial Infarction mate result due to insufficient blood supply to the working heart muscles. Sudden cardiac related deaths are common in old agef divers.
