When there is a the first degree interatrial block, the impulse from the right atrium is slowly transmitted to the left atrium, causing widening notched P wave.
When sinus arrest occurs, the electrocardiogram will show a long P-P interval, which is not multiples of the basal sinus cycle, including physiological and pathological reasons.
The 4-phase membrane potential of sinoatrial node pacing exhibits spontaneous depolarization, while the 4-phase membrane potential of ventricular myocytes remains stable.
In the spatial anatomy of the heart, the axis from the base of the heart to the apex of the heart is called the long axis, that is, the upper right side faces the lower left side.
Hypoplastic left heart syndrome is a rare congenital heart defect in which the left side of the heart is severely underdeveloped.It may affect the left ventricle, aorta, aortic valve, or mitral valve. 3D Render
In humans, Purkinje fibers are not distributed throughout the entire ventricular wall, but rather in the superficial myocardium beneath the endocardium and do not reach the epicardium.
When the first degree interatrial block occurs, the conduction time from the right atrium to the left atrium is prolonged, the P wave widens, and bimodal P wave ECG changes appear.
Clockwise rotation electrocardiogram refers to the transition of the rS waveform of the chest lead to the left chest lead, with the transition lead exceeding the V4 lead.

Clockwise and counterclockwise rotation are common electrocardiographic phenomena, mainly used to describe the evolution of R-wave amplitude in chest leads.
When Bachmann bundle conduction is interrupted, the right atrium excites the left atrium through the coronary sinus, producing positive and negative biphasic P-waves in the inferior leads.
Electric impulses can be conducted, but the conduction speed slows down, resulting in conduction delay and affecting the morphology of the P wave, PR interval, and QRS wave.
