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).
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.
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.

[table-of-contents] stripped. Whether brought on by stress, physical activity, or an extra cup of joe in the morning, most of us have all felt our heart rate quicken at one time or another.However ...
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 ...
