Bradycardia, also called bradyarrhythmia, is a resting heart rate under 60 beats per minute (BPM). [1] While bradycardia can result from various pathologic processes, it is commonly a physiologic response to cardiovascular conditioning or due to asymptomatic type 1 atrioventricular block.
It can have many potential causes, including genetics, lifestyle habits, and underlying health issues. Some types of cardiovascular disease, such as some cardiomyopathies, develop due to factors ...
Obstructive sleep apnea which is the repeated disruption of breathing during sleep due to obstruction to the airway; Inflammatory disease, such as lupus or rheumatic fever; Buildup of iron in the organs known as hemochromatosis
With paroxysmal nocturnal dyspnea specifically, it is felt while sleeping and causes a person to wake up after about 1 to 2 hours of sleep. [ 3 ] More serious forms of dyspnea can be identified through accompanying findings, such as low blood pressure, decreased respiratory rate, altered mental status, hypoxia, cyanosis, stridor, or unstable ...
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 ...
The Bezold–Jarisch reflex (also called the Bezold reflex, the Jarisch-Bezold reflex or Von Bezold–Jarisch reflex [1]) involves a variety of cardiovascular and neurological processes which cause hypopnea (excessively shallow breathing or an abnormally low respiratory rate), hypotension (abnormally low blood pressure) and bradycardia (abnormally low resting heart rate) in response to noxious ...
Severely high hypernatremia may lead to fibrillation, which may cause cardiac output to cease. Severe hyponatremia leads to both bradycardia and other arrhythmias. Hypokalemia (low potassium levels) also leads to arrhythmias, whereas hyperkalemia (high potassium levels) causes the heart to become weak and flaccid, and ultimately to fail. [16]
