Episodic supraventricular premature beats are heart beats that do not exceed five atrial or junctional premature beats per minute and are not serious. Normal heart beats begin at the sinus node and occur in a certain frequency and sequence. Premature beats are ectopic rhythms that are induced early at points other than the sinus node, and are categorized as atrial, junctional, and ventricular, with atrial and junctional premature beats collectively known as supraventricular premature beats. The difference between episodic and frequent premature beats is whether they occur more than five times per minute. Episodic supraventricular premature beats can occur in normal people, most often during late nights, smoking, alcohol abuse, physical fatigue, and emotional stress. Most people do not have any special discomfort, and they are only detected during a routine physical examination with an electrocardiogram. There is no need for special treatment, and you should not add to your psychological burden, but simply adopt good living habits and relax moderately. Occasional supraventricular premature beats, accompanied by panic attacks, chest tightness and other uncomfortable symptoms, need to consult a doctor in time to clarify whether there is a pathologic problem, and according to the doctor’s advice to actively treat.
