Abstract:
Analysis of the dynamics of changes in the end part of the ECG ventricular complex in 311 patients with rheumatic heart disease and stages IIA, IIB, and III circulatory insufficiency after treatment with preparations of digitalis and their combination with biologically active substances (orotic acid, vitamin B12, calcium pantothenate, ATP, methionine, inosi-F) is presented. When digitalis glycosides are used with preparations that have an effect on the nucleic acid synthesis and energy production, the "digitalis--induced" changes in the end part of the ECG ventricular complex are less marked while the clinical effect of treatment is more appreciable

Correlation between ECG and Cardiac Cycle
A cardiac action potential originates in the SA node and spreads throughout the atria and the AV node in approximately 0.03 seconds. This results in the P wave in an ECG and triggers atrial contraction. The action potential is then briefly slowed at the AV node, allowing the atria to contract and fill the ventricles with blood before...
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.
