Image Integration and Intracardiac Recordings of Sustained Ventricular Tachycardia From the Apex of the PMPM (A) Visualization of the cryocatheter at the apex of the PMPM by ICE. At the bottom, 12-lead ECG and intracardiac recordings. The VEGM-QRS interval is 28 ms at the effective ablation site. No Purkinje potentials were recorded at this location. (B) Same patient. Visualization of the cryocatheter at the apex of the PMPM by image integration with cardiac multidetector computed tomography. (Bottom) Pace mapping at the effective ablation site at the apex of the PMPM. ECG = electrocardiogram; ICE = intracardiac echocardiography; VEGM-QRS = interval between the earliest activation (VEGM) during the clinical arrhythmia and the QRS, at the effective lesion site.
