Premature beats are abbreviated as premature beats. It refers to the heart beat caused by premature impulses from ectopic pacemakers and is the most common arrhythmia. It may occur in the setting of sinus or ectopic (eg, atrial fibrillation) rhythm. It may occur sporadically or frequently, and may occur irregularly or regularly after every or every few normal beats, forming bigeminy or coupled premature beats. According to the site of origin, it can be divided into four types: sinus, atrial, atrioventricular junction and ventricular. Among them, ventricular premature beats are the most common, followed by atrial premature beats, and nodal premature beats are less common. Premature sinus beats are rare. Premature beats can be seen in normal people or in patients with organic heart disease, and are common in coronary heart disease, rheumatic heart disease, hypertensive heart disease, cardiomyopathy, etc.

Premature beats can also be seen in quinidine, procainamide, digitalis or antimony poisoning; hypokalemia; mechanical stimulation of the heart during heart surgery or cardiac catheterization, etc.

Premature beats can occur in normal people. But it is more likely to occur in patients with cardiac neurosis and organic heart disease. Emotional excitement, nervous tension, fatigue, indigestion, excessive smoking, drinking or drinking strong tea can all cause attacks. There may also be no obvious triggers. The toxic effects of digitalis, barium, quinidine, sympathomimetic drugs, chloroform, cyclopropane anesthetics, potassium deficiency, and heart surgery or cardiac catheterization can all cause attacks. Coronary heart disease, advanced mitral valve disease, heart disease, myocarditis, hyperthyroidism heart disease, mitral valve prolapse, etc. are prone to premature beats.

In the above article, we introduced a common symptom, which is dizziness, palpitations and shortness of breath. We know that the occurrence of dizziness, palpitations and shortness of breath are generally symptoms of premature beats.
