If bradycardia is accompanied by premature beats, it is recommended to go to the hospital to improve the electrocardiogram and other related tests, and consult the cardiology department for a clear diagnosis. An ECG can clarify the heart rate, differentiate the type of premature beats, and determine whether they are frequent or occasional. If the heart rate is 50-60 beats per minute at rest, and there is no discomfort or other arrhythmia, regular follow-up is recommended. If the heart rate is lower than 50 beats per minute, you can take medication to increase the heart rate under the guidance of your doctor and have regular checkups. The type of premature beats can be determined by ECG. Ventricular premature beats or atrial premature beats are episodic, and it is recommended to follow up with the doctor, as episodic premature beats can be seen in normal people. If the premature beats are frequent, or even occur in duplex or triple rhythm, 24-hour ECG examination should be further improved, and then take therapeutic drugs, such as metoprolol, under the guidance of the doctor, and review the ECG regularly. If there are symptoms such as cardiac discomfort, it is necessary to consult the doctor and treat the disease actively in order to avoid delaying the condition.
