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.
Because of the slow conduction of atrioventricular node, the PR interval of adult ECG should be greater than 120ms. This physiological phenomenon is called atrioventricular delay.
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

Sinus heart rate less than 60 beats per minute in adults is called sinus bradycardia. A sinus heart rate of 40 to 50 beats per minute is moderate sinus bradycardia, and patients may have symptoms such as palpitations and dizziness.
The autonomic frequency of the sinoatrial node is the fastest, and other secondary pacemakers are controlled through mechanisms of preemptive occupation and overspeed suppression.
When the blood potassium concentration increases to a certain extent, atrial muscle paralysis accompanied by ventricular conduction disorder, ECG without sinus P wave accompanied by wide QRS waves.
Sinus heart rate less than 60 beats per minute in adults is called sinus bradycardia. A sinus heart rate of 40 to 50 beats per minute is moderate sinus bradycardia, and patients may have symptoms such as palpitations and dizziness.
