: Short QT syndrome is a malignant repolarisation disorder characterised by short QT intervals. We present a previously asymptomatic 14-year-old male patient with negative family history, who suffered a sudden cardiac arrest while playing basketball and diagnosed with short QT syndrome to make emphasis on the fact that although very rare patients with this syndrome may experience cardiac arrest during exercise.
