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.
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]
The ventricular tachycardia may take a characteristic form known as bidirectional ventricular tachycardia. This form of ventricular tachycardia occurs relatively infrequently, but if seen is suggestive of an underlying diagnosis of CPVT or the related condition Andersen-Tawil syndrome.

Spinal and bulbar muscular atrophy (SBMA), popularly known as Kennedy's disease, is a rare, adult-onset, X-linked recessive lower motor neuron disease caused by trinucleotide CAG repeat expansions in exon 1 of the androgen receptor (AR) gene, which results in both loss of AR function and toxic gain of function.
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]
