Frequent premature beats are serious and require prompt medical attention. Frequent premature beats are a common arrhythmia when they occur ≥5 times a minute. Common premature beats include atrial premature beats and ventricular premature beats, which can be clearly diagnosed and differentiated from other types of premature beats by electrocardiogram (ECG). Occasional premature beats can be seen in normal people, and regular checkups are sufficient without special treatment. However, frequent atrial premature beats may induce supraventricular tachycardia, and frequent ventricular premature beats may induce ventricular tachycardia, ventricular fibrillation, affecting hemodynamics and even life-threatening, and frequent premature beats are often a manifestation of organic cardiac pathology, so frequent premature beats are still more serious, and need to be consulted in time. In daily life, if there is discomfort in the precordial area, panic, chest tightness and other suspicious symptoms, it is necessary to consult a doctor in time to avoid delaying the condition.
