Quinidine is an antiarrhythmic drug that may reduce the chance of serious abnormal heart rhythms occurring in some people with Brugada syndrome. [10] [45] It is most frequently used in people with Brugada syndrome who have an ICD and have experienced several episodes of life-threatening arrhythmias, but may also be used in people at high risk ...
Those affected by arrhythmogenic cardiomyopathy may not have any symptoms at all despite having significant abnormalities in the structure of their hearts. [6] If symptoms do occur, the initial presentation is often due to abnormal heart rhythms (arrhythmias) which in arrhythmogenic cardiomyopathy may take the form of palpitations, or blackouts. [7]
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. [10]
A type of a deadly ventricular arrhythmia - Ventricular fibrillation pattern seen on an ECG: Specialty: Cardiology Causes: Ion channelopathies: Long QT syndrome (LQTS), Brugada syndrome, CPVT (catecholaminergic polymorphic ventricular tachycardia), PCCD (progressive cardiac conduction defect), Early repolarization syndrome, Mixed sodium channel ...
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.
There is no cure for Brugada syndrome, but the condition may be treated using an implantable cardioverter defibrillator (ICD). [3] Medications to help control the abnormal heart rhythms include isoproterenol in those who are acutely unstable, and quinidine. [4] The family members of a patient with Brugada syndrome may require testing for the ...
In cardiology, genetic conditions such as Brugada syndrome can share features with related disorders caused by mutations in the same gene.An overlap syndrome can be seen whereby a mutation in the SCN5A gene encoding the cardiac sodium channel causes a reduction in the peak sodium current leading to the typical ECG features of Brugada syndrome, but which simultaneously increases the sustained ...
Wolff–Parkinson–White syndrome (WPW) syndrome is a known cause of arrhythmia in young people. It causes supraventricular tachycardia during exercise. Most of the time this causes cessation of exercise when the SVT occurs. It can lead to cardiac arrest but generally does not.
