[Results of electrocardiographic examinations of the Saliut-5 crews in flight]
Abstract:
In Salyut-5 crewmembers, electrocardiograms were recorded in 12 standard and D--S leads. No marked changes in bioelectric properties of the myocardium were detected. However, during the second part of the mission B. V. Bolynov and V. M. Zholobov showed changes in the terminal portion of the ventricular complex in the left sternal leads. It is presumed that they were induced by repolarization anomalies due to neurohormonal effects on myocardial metabolism. Members of the second crew did not exhibit similar electrocardiographic changes.

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.
