Fig. 2From: Ventricular fibrillation treated by cryotherapy to the right ventricular outflow tract: a case reportElimination of ventricular ectopy by cryoablation. Ectopic beats occurring consistently every second beat are eliminated within 10 seconds of the cooling of the ablation catheter to –80 °C as demonstrated by the cooling artefact on the ablation D bipolar electrogram. Radiological images of the cryoablation catheter at the site of successful ablation are shown on the rightBack to article page
