Heart rate change of healthy volunteers in a simulated dive experiment

Prashant Laljibhai Rajdeep, Ramesh Kantilal Patel, Dharmesh Patel.


Background: Key components of the diving response (apnoea, bradycardia, peripheral vasoconstriction, redistribution of cardiac output etc.) were found in essentially all species analyzed, and were generally taken to be biological adaptations.

Aims & Objective: To determine change in the heart rate (HR) in a simulated dive experiment in human volunteers. Materials and

Materials and Methods: In this study, 30 healthy adult male volunteers without cardio-respiratory illness participated. They held their breath in air and then in water at around 15⁰C in a plastic tub for 30 seconds at our laboratory. Their HR was measured using an automated instrument (Schiller’s multipara monitor).

Results: 1st part of experiment (breath holding in air) has shown no significant change in HR during 30 sec, while in the 2nd part (breath holding in water) has shown a significant change in the heart rate – on an average, from 108.97 to 70.8; with a difference of 38.17 (p
