Any update on treatment for sustained ventricular tachycardias?

Yea: There is VT foci cardiac ablation, there is scar mapping- if VT is related to scar, there is mapping using pacing- if the VT causes your blood pressure to drop, there are a hand- full of anti arrhythmic medications that can be used and, of course, there is the implantable cardioverter defibrillator. Request to speak with a cardiac electrophysiologist about your options.
