Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
CASE GROUP
patients with chronic infarction undergoing catheter ablation of ventricular arrhythmias
CardioZ multifrequency impedance recording system
Patients will be submitted to mapping of both voltage and tissue impedance. The accuracy of the two maps identifying the extent and transmurality of the infarction will be assesssed by gadolinium imaging.
Interventions
