A patient with hea failure developed recurrent sustained monomorphic vt .Treatment is/are -

Sustained monomorphic VT associated with nonischemic cardiomyopathy is usually due to scar-related reentry. On cardiac MR imaging, scars are detectable as areas of delayed gadolinium enhancement and are more often intramural or sub-epicardial in location as compared with patients with prior MI. Any cardiomyopathic process can cause scars and VT, but cardiac sarcoidosis, Chagas disease, and cardiomyopathy due to Lamin A/C mutations are paicularly associated with monomorphic VT . An ICD is usually indicated with additional drugs or catheter ablation for control of recurrent VT. Harrison 20thed pg 1758
