Synopsis

A heart rhythm originating in the sinus node with heart rate less than about 60 beats per minute. Although generally benign, patients may report dizziness, lightheadedness, syncope, or near syncope in some cases. Potential causes include athletic conditioning, sick sinus syndrome, rate-lowering medications (eg, beta blockers, nondihydropyridine calcium channel blockers, ivabradine, amiodarone, digoxin, lithium), obstructive sleep apnea, enhanced vasovagal activity, hypothyroidism, acute myocardial infarction, elevated intracranial pressure, familial ion channelopathies, and certain infectious causes (eg, Lyme disease, babesiosis, Chagas disease).
