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.
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]
A syndrome is a set of medical signs and symptoms that are correlated with each other. ... Brugada syndrome: Cantú syndrome: genetic (Chromosome 12, autosomal dominant)
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]
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]

According to Morton, the eight signs that you have "eldest daughter syndrome" are as follows: You have an intense feeling of responsibility. You are an overachiever, Type A and very driven.
Examples of these inherited arrhythmia syndromes include Long QT syndrome (LQTS), Brugada Syndrome, Catecholaminergic polymorphic ventricular tachycardia, and Short QT syndrome. Many are also associated with environmental or neurogenic triggers such as response to loud sounds that can initiate lethal arrhythmias. [29]
