Brugada syndrome; Other names: Sudden unexplained nocturnal death syndrome, bangungut, pokkuri death syndrome [1] Typical type 1 ECG changes seen in Brugada syndrome: Specialty: Cardiology: Symptoms: Passing out, sudden cardiac death [2] Usual onset: Adulthood [2] Causes: Genetics, certain medication [2] Risk factors: Family history, Asian ...
The resting 12-lead ECG is a useful test to differentiate CPVT from other electrical diseases of the heart that can cause similar abnormal heart rhythms. Unlike conditions such as long QT syndrome and Brugada syndrome, the resting 12-lead ECG in those with CPVT is generally normal. [8]
In a 2008 study it was found that over half of SADS deaths could be attributed to inherited heart disease: unexplained premature sudden deaths in family, long QT syndrome, Brugada syndrome, arrhythmogenic right ventricular cardiomyopathy and others. [1]
The condition presents early in life and the average life expectancy is 2.5 years with death most commonly caused by ventricular arrhythmias. Many children with Timothy syndrome who survive longer than this have features of autism spectrum disorder. Timothy syndrome is caused by variants in the calcium channel Cav1.2 encoded by the gene CACNA1c ...
Recently described syndromes such as the Brugada Syndrome may give clues to the underlying mechanism of ventricular arrhythmias. In the Brugada syndrome, changes may be found in the resting ECG with evidence of right bundle branch block (RBBB) and ST elevation in the chest leads V1–V3, with an underlying propensity to sudden cardiac death.

Jervell and Lange-Nielsen syndrome (JLNS) is a rare type of long QT syndrome associated with severe, bilateral sensorineural hearing loss. [2] Those with JLNS are at risk of abnormal heart rhythms called arrhythmias, which can lead to fainting, seizures, or sudden death.
Short QT syndrome (SQT) is a very rare genetic disease of the electrical system of the heart, and is associated with an increased risk of abnormal heart rhythms and sudden cardiac death. [1] The syndrome gets its name from a characteristic feature seen on an electrocardiogram (ECG) – a shortening of the QT interval.
All infants with TGA will need surgery to correct the defect. Life expectancy is only a few months if corrective surgery is not performed. [citation needed] Before surgery: For newborns with transposition, prostaglandins can be given to keep the ductus arteriosus open which allows for the mixing of the otherwise isolated pulmonary and systemic ...
