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.
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.

Long QT syndrome can cause syncope when it sets off ventricular tachycardia or torsades de pointes. The degree of QT prolongation determines the risk of syncope. [20] Brugada syndrome also commonly presents with syncope secondary to arrhythmia. [20] Typically, tachycardic-generated syncope is caused by a cessation of beats following a ...

Long QT syndrome is estimated to affect 1 in 7,000 people. [6] Females are affected more often than males. [6] Most people with the condition develop symptoms before they are 40 years old. [6] It is a relatively common cause of sudden death along with Brugada syndrome and arrhythmogenic right ventricular dysplasia. [3]
That was the conclusion of Gray’s clinical research trial in which adaptive disclosure therapy was used with 44 active-duty combat Marines with PTSD and moral injury. In six 90-minute sessions, Gray found that the Marines experienced “substantive” improvement in their symptoms.
