In clinical practice, elderly people over age 65 and young athletes of both sexes may have sinus bradycardia. [1] The US Centers for Disease Control and Prevention reported in 2011 that 15.2% of adult males and 6.9% of adult females had clinically defined bradycardia (a resting pulse rate below 60 BPM). [41]
Sinus bradycardia is a sinus rhythm with a reduced rate of electrical discharge from the sinoatrial node, resulting in a bradycardia, a heart rate that is lower than the normal range (60–100 beats per minute for adult humans).
Bradycardia is a slower than normal heartbeat, at around 40–60 beats per minute. Cardiomegaly is the state of an enlarged heart, and cardiac hypertrophy the thickening of the muscular wall of the heart, specifically the left ventricle , which pumps oxygenated blood to the aorta .
One Harvard study taking into account more than 14,000 people over 50 found that people more satisfied with the aging process were at a lower risk for diabetes, stroke, cancer and heart disease.
Overall incidence of sinus node dysfunction increases with age [10] with 1 in 1000 in adults over 45 years old [6] and 1 in 600 cardiac patients over 65 years old. [5] Sinus node dysfunction is the primary indication for approximately 30%-50% of all pacemaker implantation in the United States. [ 10 ]
Falls can be serious — and even deadly — in older adults and the elderly. They’re also common: More than 1 out of 4 older adults falls each year, but less than half of those inform their ...
Hypotension, also known as low blood pressure, is a cardiovascular condition characterized by abnormally reduced blood pressure. [1] Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps out blood [2] and is indicated by two numbers, the systolic blood pressure (the top number) and the diastolic blood pressure (the bottom number), which are the ...
Non-commercial aviation is remarkably dangerous, with hundreds of accidents occurring each year. There were 1,248 accidents in 2009, 1,236, and in 2010, and 937 so far this year. In total, 1,112 ...
