Top 5 Causes of Slow Heart Rate (Bradycardia)

Medications are the third most common cause of bradycardia, responsible for around 25% of cases.
Hypertension and antiarrhythmic medications, such as beta-blockers (e.g., atenolol, metoprolol) and calcium channel blockers (e.g., diltiazem, verapamil), commonly cause bradycardia.
Digoxin, used for heart failure and arrhythmias, and antiarrhythmic drugs like amiodarone are also noted for causing bradycardia.
Treatment for medication-induced bradycardia includes dose reduction or changing the medication.
If medication adjustments are ineffective, the permanent implantation of a pacemaker may be necessary.
Hypothyroidism is a less common cause, characterized by the thyroid gland releasing fewer thyroid hormones than normal, which slows metabolism and decreases heart rate.
Treatment for hypothyroidism involves levothyroxine, which replaces the deficient thyroid hormone.
Sleep apnea, particularly prevalent at night, is the fifth most common cause of bradycardia, responsible for 15% of cases.
Sleep apnea-related bradycardia is commonly associated with obesity and overweight.
Solutions for sleep apnea-induced bradycardia include weight loss, avoiding sleeping on one's back, and avoiding alcohol and sedatives.
Surgery may be considered a last resort for treating sleep apnea if other methods fail.
Less common causes include electrolyte imbalances during kidney disease and some infectious diseases, such as Lyme disease.
Supplements like omega-3 fatty acids have a cardioprotective function and can modulate heart rate.
Coenzyme Q10 supports energy production and may improve heart function and heart rate.
Magnesium is effective in cases of deficiency, as it can prevent arrhythmias, with potassium and calcium also playing potential roles.
