[Features of the ECG in acute altitude sickness]
Abstract:
Using the Minnesota Code, we analysed ECGs of 58 subjects with smooth adaptation to high altitude (3.600 m) and of 70 patients with acute mountain sickness. In both groups, the 30-day sojourn at high altitude was characterized by ECG signs of the right heart overload; these signs were more marked in patients with acute mountain sickness. It was demonstrated that baseline ECGs (recorded before the ascent) of subjects predisposed to the development of acute mountain sickness showed a higher incidence of right-ventricular hypertrophy, right-atrial hypertrophy, and tachycardia. These ECG features can be used in the prognosis of acute mountain sickness.

Electrocardiogram Fundamentals
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.

Sinus Node Arrhythmias
Sinus Bradycardia: Originating from the sinoatrial (SA) node, sinus bradycardia involves slower impulses, resulting in a heart rate of less than 60 beats per minute (bpm). Causes include sleep, vagal stimulation, beta-blockers, hypothyroidism, and...
