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).
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 .
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).
They’re also common: More than 1 out of 4 older adults falls each year, but less than half of those inform their doctor, according to the Centers for Disease Control and Prevention (CDC ...
Arrhythmia affects millions of people. [4] In Europe and North America, as of 2014, atrial fibrillation affects about 2% to 3% of the population. [ 9 ] Atrial fibrillation and atrial flutter resulted in 112,000 deaths in 2013, up from 29,000 in 1990. [ 10 ]
Often sinus node dysfunction produces no symptoms, especially early in the disease course. Signs and symptoms usually appear in more advanced disease and more than 50% of patients will present with syncope or transient near-fainting spells as well as bradycardias that are accompanied by rapid heart rhythms, referred to as tachycardia-bradycardia syndrome [4] [5] Other presenting signs or ...
Bradycardia (slow heart rate) Hypotension (low blood pressure) Beta blockers can also interfere with certain other medications, including medication for heart disease and other conditions.
A high pulse pressure combined with bradycardia and an irregular breathing pattern is associated with increased intracranial pressure, a condition called Cushing's triad seen in people after head trauma with increased intracranial pressure. [16] Common causes of widening pulse pressure include: [3] [medical citation needed] Anemia; Aortic ...
