Depolarization/conduction [greater than or equal to] 1 of 3 abnormalities: parameters in the absence of a QRS duration o [greater than or * Epsilon wave (reproducible equal to] 110 ms on the standard low-amplitude signals between the ECG.
His post-cardioversion ECG showed persistent T-wave inversions in leads [V.sub.1], [V.sub.2], and [V.sub.3] as well as epsilon waves [Figure 2].
These included the documentation of sustained VT of the morphology described in Table 1 (arrhythmia criteria), the presence of epsilon waves (depolarization criteria) and T-wave inversions in [V.sub.1], [V.sub.2], and [V.sub.3] in the absence of complete Right Bundle Branch Block (RBBB) (repolarization criteria).
Twelve-lead electrocardiogram (ECG) showed inverted T waves and epsilon wave in VI-V4 (Fig.
Complete or incomplete right bundle brunch block, prolongation of right precordial (IRS duration and a small, discrete wave just beyond the (IRS in particularly Vi, designated as epsilon wave, are the depolarization abnormalities.
On admission, the electrocardiogram showed that T-wave inversions were visible in most leads, QRS duration was prolonged with 120 ms, and the terminal depolarizations might be interpreted as
epsilon waves in leads V1–V5 [Figure 1]a arrows].
