| Abstract |
| Introduction: cardiac arrhythmia is a disturbance in the rhythm or heartbeat. this study aims to investigate the effect of water diving on cardiac arrhythmias in military divers during war or skill-learning exercises. Materials and methods: In this narrative review, related information reached from the SID, Google Scholar, and Pub Med databases, by searching the keywords ”Military Divers”, “Cardiac Arrhythmias”, “SNS”, and “PNS” in the period of 2010 to 2023. Among 138 articles irrelevant and repetitive articles were removed and articles related to divers and navy were analyzed. Result: the results of this article were extracted from 36 articles, being in a deep water environment leads to several arrhythmias with simultaneous stimulation of the sympathetic nervous system (SNS) and parasympathetic (PNS) in military divers and its mechanism relates to several factors. Hydrostatic tension or water pressure causes sympathetic stimulation by increasing the pressure on the body's vessels. On the other hand, the lack of oxygen in deep waters increases the body's need for oxygen, therefore, the parasympathetic system activity increases. Also, the stress of the environment like war conditions or darkness underwater causes more sympathetic activity. This simultaneity of sympathetic and parasympathetic stimulation can prevent the proper electrical activity of the heart by disrupting the nervous system. In some cases, a trigeminocardiac reflex (TCR) following excessive vagal stimulation is possible. frequent exposure to these arrhythmias can cause malignant problems such as reduction of QT interval in the ECG, left ventricular hypertrophy, reduction of left ventricular diastolic function, premature repolarization, AV node block, and defects in the nervous system of the heart. Also, these malignant arrhythmias can lead to death in military divers, which sometimes are mistakenly diagnosed as drowning or hypothermia. Discussion: To avoid the simultaneous activity of SNS and PNS studies recommended avoiding sudden diving into cold water and evaluating the military diver. connecting HRV measurement sensors and transmitting cardiac information to the health control center, is helpful in early recognizing the arrhythmia in a military diver and preventing the occurrence of acute and chronic secondary consequences. |
