ClinConnect Summary

Patients with ischemic ventricular tachycardia and implanted defibrillatior (ICD) will be sent to catheter ablation according to current guidelines (ESC and/or HRS). At the initial procedure the scar will be mapped with an ablation catheter and a high density catheter and all abnormal endocardial electrical potentials will be marked on a three-dimensional electro-anatomical (3DEAM) map; late potentials, local abnormal ventricular activity and decrement evoked electrical potentials. Afterwards, programed ventricular stimulation will be performed with an intent to induce sustained ventricular...
