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).
The Dutch call the presence a nachtmerrie, the night-mare. [17] The "merrie" comes from the Middle Dutch mare, an incubus who "lies on people's chests, suffocating them". This phenomenon is known among the Hmong people of Laos, [20] who ascribe these deaths to a malign spirit, dab tsuam (pronounced "dah chua"), said to take the form of a ...
People who practice sports may have sinus bradycardia, because their trained hearts can pump enough blood in each contraction to allow a low resting heart rate. [ medical citation needed ] Sinus bradycardia can also be an adaptive advantage; for example, diving seals may have a heart rate as low as 12 beats per minute, helping them to conserve ...
However, oftentimes lower heart rates can be totally normal, and a well-trained athlete can have a normal heart rate in the 50s or as low as 40 without any cause for concern, he notes.
Always be aware of the possible side effects of prescription and over-the-counter medicines, as some may cause your heart rate to increase, decrease or beat with an irregular rhythm.
Its fatality rate is about 65% even with prompt CPR and defibrillation, and more than 80% without. [4] [5] Age 35 serves as an approximate borderline for the likely cause of sudden cardiac death. Before age 35, congenital abnormalities of the heart and blood vessels predominate.
Neurogenic shock is a distributive type of shock resulting in hypotension (low blood pressure), often with bradycardia (slowed heart rate), caused by disruption of autonomic nervous system pathways. [1] It can occur after damage to the central nervous system, such as spinal cord injury and traumatic brain injury.
The resting heart rate in children is much faster. In athletes, however, the resting heart rate can be as slow as 40 beats per minute, and be considered normal. [citation needed] The term sinus arrhythmia [26] refers to a normal phenomenon of alternating mild acceleration and slowing of the heart rate that occurs with breathing in and out ...
