Sudden arrhythmic death syndrome (SADS) is a sudden unexpected death of adolescents and adults caused by a cardiac arrest. However, the exact cause of the cardiac arrest, and thus the exact cause of death, is unknown. These deaths occur mainly during sleep or at rest. [7] One type of conduction defect known as Brugada syndrome can be ...
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.
There are many inherited conditions and heart diseases that can affect young people which can subsequently cause sudden death without advance symptoms. [ 16 ] Causes of SADS in young people include viral myocarditis , long QT syndrome , Brugada syndrome , Catecholaminergic polymorphic ventricular tachycardia , hypertrophic cardiomyopathy and ...
Pulseless electrical activity (PEA) is a form of cardiac arrest in which the electrocardiogram shows a heart rhythm that should produce a pulse, but does not.Pulseless electrical activity is found initially in about 20% of out-of-hospital cardiac arrests [1] and about 50% of in-hospital cardiac arrests.
Despite being the nation’s biggest killer for 100 years, a new survey finds many adults don’t know that heart disease is the leading cause of death in the U.S. Heart disease is the leading ...
This is followed by sudden cardiac death in the absence of treatment. [2] Ventricular fibrillation is initially found in about 10% of people with cardiac arrest. [1] Ventricular fibrillation can occur due to coronary heart disease, valvular heart disease, cardiomyopathy, Brugada syndrome, long QT syndrome, electric shock, or intracranial ...
The underlying causes of sudden cardiac arrest can result from cardiac and non-cardiac etiologies. The most common underlying causes are different, depending on the patient's age. Common cardiac causes include coronary artery disease, non-atherosclerotic coronary artery abnormalities, structural heart damage, and inherited arrhythmias. Common ...
[1] [2] When said person bends forward, it causes a further increase in ventricular filling pressures that causes dyspnea, especially in patients with lower cardiac indices. [ 1 ] [ 2 ] The term "bendopnea" (meaning "bent" and "breath") was coined to be easily identifiable among patients and physicians.
