Brugada syndrome (BrS) is a genetic disorder in which the electrical activity of the heart is abnormal due to channelopathy. [2] It increases the risk of abnormal heart rhythms and sudden cardiac death. [2]

Long QT syndrome, the most common form of cardiac channelopathy, is characterized by prolonged ventricular repolarization, predisposing to a high risk of ventricular tachyarrhythmias (e.g., torsade de pointes), syncope, and sudden cardiac death.

Medical therapy of chronic aortic regurgitation that is stable and asymptomatic involves the use of vasodilators. [1] Trials have shown a short-term benefit in the use of ACE inhibitors or angiotensin II receptor antagonists , nifedipine , and hydralazine in improving left ventricular wall stress, ejection fraction, and mass. [ 5 ]
Brugada syndrome can result in ventricular fibrillation and potentially death. It is a major cause of sudden unexpected cardiac death in young, otherwise healthy people. [ 11 ] While the characteristic patterns of Brugada syndrome on an electrocardiogram may be seen regularly, often the abnormal pattern is only seen spontaneously due to unknown ...
The plethora of terms reflects imprecision and uncertainty in their definition, controversy, and care taken to avoid stigmatising affected people. [7] Risk factors for medically unexplained symptoms are complex and include both psychological and organic features, and such symptoms are often accompanied by other somatic symptoms attributable to ...
