Epidemiology and Demographics
Among people under 25 years of age, approximately 30% have sinus bradycardia[1]. During sleep, heart rates may decline by 25 beats per minute in young patients, and 15 beats per minutes in the elderly. Heart rates of 30 beats/minute and pauses of up to 2 seconds are not uncommon in healthy people [2][3][4]
