Fig. 2. — Electrical activations were recorded until long-duration ventricular fibrillation (LDVF) abruptly terminated. A: an electrogram (top) and its temporal derivative (bottom) from a plaque in a control heart demonstrate the termination of LDVF. Purkinje activations were recorded in control hearts until the termination of LDVF. B: an electrogram (top) and its temporal derivative (bottom) in a Lugol-ablated heart show spontaneous termination of LDVF. No Purkinje activations were recorded in Lugol-treated hearts.
