Common causes of sinus bradycardia

Sinus bradycardia is caused by heart disease, heart disease, and drug effects.

1. Physiological effects.

Slow heart rate may occur in athletes, older people, and people who sleep.

2. Heart disease.

Sinus bradycardia may occur in patients with temperamental heart disease such as myocarditis, cardiomyopathy, and coronary heart disease.

3. Drug effects

. Long-term use of antiarrhythmic drugs such as digitalis, propafenone, and methyldopa may reduce the frequency of heart rate, resulting in sinus bradycardia.
