Abstract
The short QT syndrome (SQTS) is a cardiac channelopathy associated with a propensity for cardiac arrhythmias in persons with a structurally normal heart [1-3]. Although victims of sudden cardiac death (SCD) tend to fit in certain categories, the cause of SCD may be sometimes completely unpredictable. Herein, we present the case of a young man with a history of succesfully resuscitated SCD and recurrent syncopal attacks with unknown etiology. A 20-year-old man presented to our cardiology out-patient clinic due to several episodes of transient loss of conciousness not associated with emotional stress or exercise during the last 6 months. The patient was afebrile with blood pressure of 110/70 mmHg, heart rate of 60 bpm, and oxygen saturation of 99% by pulse oximetry. Cardiac examination showed a regular heart rhythm with no murmurs. The rest of the physical examination was unremarkable. Electrocardiography (ECG) demonstrated a sinus rhythm, 55 bpm; PR interval: 132 ms; QRS duration: 85 ms; QTc: 313 ms (Bazzet formula); and J-point to T-wave-peak interval: 140 ms (Figure 1).
