Although many of those with Brugada syndrome do not have any symptoms, Brugada syndrome may cause fainting or sudden cardiac death due to serious abnormal heart rhythms, such as ventricular fibrillation or polymorphic ventricular tachycardia. [9] Blackouts may be caused by brief abnormal heart rhythms that revert to a normal rhythm spontaneously.
Brugada syndrome also commonly presents with syncope secondary to arrhythmia. [20] Typically, tachycardic-generated syncope is caused by a cessation of beats following a tachycardic episode. This condition, called tachycardia-bradycardia syndrome, is usually caused by sinoatrial node dysfunction or block or atrioventricular block. [21]
Rare diseases called ion channelopathies may play a role such as long QT syndrome (LQTS), Brugada syndrome (BrS), CPVT (catecholaminergic polymorphic ventricular tachycardia), progressive cardiac conduction defect (PCCD), early repolarization syndrome, mixed sodium channel disease, and short QT syndrome. [13]
Sudden unexplained nocturnal death syndrome may refer to: Brugada syndrome , a genetic disorder in which the electrical activity within the heart is abnormal Sudden arrhythmic death syndrome (SADS), a sudden unexpected death of adolescents and adults, mainly during sleep
Abnormalities in this system occur in relatively rare genetic diseases such as Long QT syndrome, Brugada syndrome, and Catecholaminergic polymorphic ventricular tachycardia, all associated with sudden death. Consequently, autopsy-negative sudden cardiac deaths (no physical abnormalities identified) may comprise a larger part of the ...
