The 12-lead ECG shows the Wolff–Parkinson–White (WPW) syndrome (Fig. 1, colour panel, black arrow: delta wave) and premature ventricular contractions (PVCs). The PVCs come from the right ventricular outflow according to the electrocardial vector (Fig. 1, colour panel, red arrow).
Fig. 1
Colour panel the usual 12-lead surface ECG. Paper speed is as usual (25 mm/s), and voltage is half the usual (5 mv/mm). Black arrow = delta wave, red arrow = premature ventricular contraction. Black panel the significant episode documented by Holter monitoring. Thin black arrow = delta wave, thin red arrow = VT, thick red arrow = SVT. Paper speed is as usual (25 mm/s), and voltage is as usual (10 mv/mm)
