Premature beats are physiologically caused by fast heartbeats and do not require treatment. When symptoms are severe, they can be treated with medications such as beta-blockers and non-dihydropyridines. Premature beats are categorized into atrial, ventricular and atrioventricular junctional premature beats, with ventricular premature beats being the most common. Atrial premature beats are physiologically caused by fast heartbeats and usually do not require treatment. They are usually caused by drinking strong tea, coffee, cigarettes and alcohol. By resting properly, quitting smoking and avoiding strong tea and coffee, the premature beats will naturally disappear and the heartbeat will return to normal. When the symptoms of premature fast heartbeat appear obvious, it can be treated with beta blockers such as metoprolol, non-dihydropyridines such as verapamil and propafenone. Fast ventricular premature heartbeats do not need to be treated with medications if there is no organic heart disease and the symptoms are not severe. If the symptoms are severe, it can be treated with beta-blockers such as metoprolol, non-dihydropyridines such as verapamil and propafenone. If there is organic heart disease, the principle is to treat the heart’s own disease and not to deal with premature ventricular beats separately. Atrioventricular junctional premature beats are treated in the same principle as the appeal. Do not be too nervous when you have a fast heartbeat, keep resting and eating healthily. You can do some relevant electrocardiogram, cardiac ultrasound and other examinations, regular follow-up and treatment under the guidance of the physician.
