[Hemodynamic characteristics during 2-chamber electrostimulation of the heart]
Abstract:
Cardiac output was investigated in coronary patients with temporary (15) and permanent (16) programmed two-chamber electrostimulation of the heart, using different induced atrioventricular interval values. The study was based on integral rheoplethysmography, peripheral volumetric sphygmography, sectoral echocardiography and two-dimensional doppler echocardiography with color code. The adjustment of atrioventricular interval in two-chamber cardiac electrostimulation can modulate cardiac output by means of changing the duration and rate of left-ventricular filling flow, produced by the atrial systole.

The Cardiac Cycle
The Process
Electrical signals—sent from the sinoatrial (SA) node in the right atrial wall to the atrioventricular (AV) node between the right atrium and right ventricle—cause both atria to simultaneously contract. When the signal reaches the AV node, it pauses for approximately a tenth of a second, allowing the atria to contract and empty blood into the...

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.

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.
