Conditions: Ventricular Tachycardia
Keywords: Ventricular tachycardia ventricular tachycardia ablation effects of anesthesia on VT induction programed stimulation
Allocation: NA | Intervention model: SINGLE_GROUP
Enrollment: 11
Healthy volunteers: no

Brief summary:
This research study is being done to see whether general anesthesia (GA) affects our ability to start ventricular tachycardia (VT) during an VT ablation procedure.

Data collected during this research study will help electrophysiologists and anesthesiologists to make the best decisions about the best anesthetic conditions to use to perform VT ablations.

This research study is a "pilot" study. Pilot studies are done on a small group of subjects to learn if a larger study would be useful.

Detailed description:

Arms:
arm 1: Patients undergoing ventricular tachycardia ablation will undergo programmed stimulation (PS) with minimal sedation (Versed, Fentanyl), with intravenous agents (propofol) , and finally with volatile inhalational agent (sevoflurane).

Interventions: intervention 1: Versed intervention 2: Fentanyl intervention 3: Propofol intervention 4: Sevoflurane
Intervention descriptions: intervention 1: Phase 1: Standard induction of controled sedation with intravenous agent then programed stimulation to induce ventricular tachycardia intervention 2: Phase 1: Standard induction of controled sedation with intravenous agent then programed stimulation to induce ventricular tachycardia intervention 3: Phase 2: Standard induction of GETA with intravenous agent then programed stimulation to induce ventricular tachycardia intervention 4: Phase 3: Standard induction of GETA with inhalent agent then programed stimulation to induce ventricular tachycardia
