Splet21. mar. 2016 · An S-wave was present in lead I in 56% of asymptomatic patients, 51% of patients with syncope, and 97% of patients with VF/SCD. An S-wave amplitude ≥0.1 mV, duration ≥40 ms, and area ≥1 mm 2 had negative predictive values of 98.5-99.5% and positive predictive values between 19.6% and 23.2% for VF/SCD during follow-up. SpletLarge Q and S waves in lead III distinguished athletes from patients with HCM, independent of axis and well-known ECG markers associated with HCM. The correlation between IVS thickness in patients with HCM and IIIQ+S suggests a partial explanation for this association.
