Przewidywanie nagłego zgonu sercowego na podstawie 12-odprowadzeniowego zapisu EKG

Sudden cardiac death (SCD), which is often the first manifestation of cardiovascular disease, is defined as a non-traumatic, unexpected fatal event occurring within one hour of the onset of symptoms in an apparently healthy subject. According to the current guidelines, implantable cardioverter-defibrillator therapy is recommended for the primary prevention of SCD among patients with a reduced ( i.e. less than 75/min, prolonged QTc interval (> 450 ms for men, > 460 ms for women), QRS-T angle > 90 degrees, delayed QRS transition zone (> V4), prolonged Tpeak-to-Tend (TpTe) > 89 ms and left ventri­cular hypertrophy (according to Sokolow-Lyon or Cornell criteria). This novel ECG risk score could be particularly effective for patients with left ventricular ejection fraction > 35% where risk stratification is currently unavailable.
