How does atrial escape rhythm accelerate form

The occurrence of atrial escape rhythm acceleration may be related to sinus node dysfunction, atrial pacemaker activation formation, ventricular contraction and other factors. The specific analysis is as follows:

1. The sinus node dysfunction Under

normal conditions, the pacemaker of the heart is located in the sinus node, and the sinus node controls the contraction of the heart by generating electrical pulses. When the sinus node dysfunction occurs, the heart cannot normally send pacing signals from the sinus node to trigger the atrial escape rhythm acceleration.

2. After the atrial pacemaker activation is formed

, other pacing points in the atrial tissue at the lower part of the heart will be triggered to form pulses, and the pacing points will generate electrical pulses to conduct along the atrial muscle, causing the atrial muscle to contract. The above conditions occur.

3. Ventricular contraction After the ventricular

contraction passes through the atrial conduction, the atrioventricular node and bundle branch system at the lower part of the heart will conduct electrical pulses to the ventricular muscle, causing the ventricular muscle to contract, thus causing the atrial escape rhythm to accelerate.
