Ablation lesions in the right ventricular wall of equine and swine hearts after 2,3,5-triphenyl tetrazolium chloride staining. Viable myocardium is stained dark red, whereas the necrotic ablation lesion remains unstained. It is noted that an increase in power or duration of radiofrequency energy led to an increase in lesion depth, diameter and volume.
