When the pulse beats irregularly, you should go to the hospital in time to improve the electrocardiogram and other related tests to clarify the cause. Common causes include cardiac arrhythmia, metabolic diseases such as thyroid dysfunction and poor lifestyle. 1. Arrhythmia: Most common causes are premature beats such as atrial premature beats, ventricular premature beats, atrioventricular junctional premature beats, and atrial fibrillation, which should be further diagnosed by ECG and dynamic ECG. In case of episodic premature beats, rest should be paid attention to, ensure sufficient sleep, and regular review. In the case of frequent premature beats, anti-arrhythmic drugs such as oral metoprolol and bisoprolol can be taken, and if necessary, the patient can be treated by surgery, such as radiofrequency ablation. For patients with atrial fibrillation, digitalis or beta blockers can be taken to control the ventricular rate in an appropriate range. 2. Abnormal thyroid function: the cause can be clarified through thyroid function test, levothyroxine sodium tablets can be taken to actively treat hypothyroidism, methimazole to treat hyperthyroidism, and also can take drugs to improve the symptoms of nutrient cardiac muscle. 3. Bad lifestyle: mental tension, emotional excitement, overwork, overeating, drinking a lot of strong tea or coffee, excessive alcohol consumption, smoking and other bad lifestyle, will interfere with the function of neuromodulation, aggravate the burden on the heart, increase myocardial oxygen consumption, affect the heartbeat, and will also appear irregular pulse beat. You should keep your spirit happy, have a reasonable work and rest schedule, avoid overeating and drinking, and stop smoking and drinking. The discovery of irregular pulse must be interviewed by a doctor, should be under the guidance of the doctor to improve the examination, take the relevant medication, so as to avoid delaying the condition.
