Arrhythmic premature beats may be physiological factors, but also may be the manifestation of certain diseases, such as organic heart disease, drug effects, electrolyte disorders, etc., should be timely consultation to identify the cause of the disease. 1. Physiological factors: generally in the rest is not good, drink coffee, tea, these stimulating drinks, emotional excitement, as well as smoking and drinking these, may cause physiological arrhythmia premature beats. 2.

Drugs: Drugs such as dopamine, dobutamine, and isoprenaline can cause arrhythmic premature beats if used for too long. Electrolyte disorders: severe cases can also cause arrhythmic premature beats, because electrolyte disorders can cause the stability of the cell membrane to decrease, and there will also be low potassium, resulting in a decrease in the excitability of the cell membrane, and arrhythmic premature beats symptoms. However, pathological factors can not be ruled out, it is recommended to consult a doctor in time to clarify the cause of the disease, and then give targeted treatment.
