<unk>  <unk>  is a rare inherited arrhythmogenic disorder characterized by syncopal attacks, ventricular arrhythmias, and even sudden cardiac death, mostly in young patients. It is caused by mutations in calcium handling proteins such as RyR2 and CASQ2 within the sarcoplasmic reticulum, which results in ventricular arrhythmias in the setting of a high adrenergic tone such as during physical exercise or strong emotions. Since it is caused by mutations in genes encoding for channel-proteins that regulate cardiac electrical activity,<unk>  is referred to as a channelopathy. There are no associated structural abnormalities of the heart in<unk> .
