Work is beneficial for health, but many individuals develop cardiovascular disease (CVD)
during their working lives. Occupational cardiology is an emerging field that combines …

This pre-eminent work has developed over six editions in response to man's attempts to
climb higher and higher unaided, and to spend more time at altitude for both work and …

Hypoxia increases heart rate (HR) in humans by sympathetic activation and vagal
withdrawal. However, in anaesthetized dogs hypoxia increases vagal activity and reduces …

Peripheral chemoreflex mediated increases in both parasympathetic and sympathetic drive
under chronic hypoxia may evoke bradyarrhythmias during apneic periods. We determined …

Introduction Several UK military expeditions have successfully used physiological sensors to
monitor participant's physiological responses to challenging environmental conditions. This …

Background: High altitude (HA) exposure can lead to changes in resting heart rate variability
(HRV), which may be linked to acute mountain sickness (AMS) development. Compared …

Breath-hold divers are known to develop cardiac autonomic changes and brady-arrthymias
during prolonged breath-holding (BH). The effects of BH-induced hypoxemia were …

Importance Arterial hypoxemia, electrolyte imbalances, and periodic breathing increase the
vulnerability to cardiac arrhythmia at altitude. Objective To explore the incidence of …

The presence of bradycardic arrhythmias during volitional apnea at altitude may be caused
by chemoreflex activation/sensitization. We investigated whether bradyarrhythmic episodes …

We aimed to analyze the influence of atrial fibrillation (AF) prior to hospital admission
(“prevalent”) and AF diagnosed during hospital admission (“incident”) on in-hospital …
