[Complex spatial evaluation of the electromotive force of the heart in persons with healthy hearts]
Abstract:
A complex spatial analysis of the electromotive cardiac force was performed to 150 subjects with intact hearts, aged from 20 to 55. The extend, direction and rate of the change in the direction and extend of 10, 20, 30, 40, 50, -30, -20, -10 and maximum spatial vectors were analysed. The results were processed according to the method of variation analysis, presented in diagrams and tables. The results obtained, which do not contradict those found in literature, show that the methods applied (graphic and automatic) could successfully be applied in practice and the data obtained--serve as standards for the work with the same apparatuses (Hellige EG-22 with an appliance, constructed and produced in Bulgaria.

Cardiac Action Potential
The cardiac action potential process involves a series of phases characterized by the movement of ions across the cardiac cell membranes, leading to the depolarization and repolarization of the cardiac myocytes.

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.
