Brief Summary
Unblinded, controlled, non-randomized, mechanistic study to determine whether physiological mechanisms underlying PVC are sensitive to adenosine. One hundred subjects undergoing clinically-indicated, standard-of-care cardiac electrophysiology study (EPS) procedure for PVCs will receive adenosine and/or verapamil to learn if their arrhythmias are inducible similarly to sustained ventricular tachycardia.

Outcome Measures
Primary Outcomes (2)
Effects of Adenosine on premature ventricular contractions (PVCs) as measured by EKG;
The metrics that will be collected will be: * Baseline frequency of premature ventricular contractions (PVCs) * Frequency of premature ventricular contractions (PVCs) during adenosine administration
baseline
Effects of verapamil on premature ventricular contractions (PVCs) as measured by EKGs.
The metrics that will be collected will be: * Baseline frequency of premature ventricular contractions (PVCs) * Frequency of premature ventricular contractions (PVCs) during verapamil administration
baseline
Study Arms (1)
Adenosine/ Verapamil Arm
OTHERAdenosine: 0.84 mg/kg IV (140 mcg/kg/minute IV for 6 minutes) Verapamil: 0.15 mg/kg IV Adenosine is known to terminate ventricular arrhythmias that are due to triggered activity (ref Lerman). To study the effects of adenosine on PVC, the investigators will administer Verapamil to slow down the heart initially and adenosine after catheters are introduced to patients who are being treated for symptomatic PVC and have consented to treatment with an invasive electrophysiology study and catheter ablation.
Interventions
Adenosine: 0.84 mg/kg (140 mcg/kg/minute IV for 6 minutes) Verapamil 0.15 mg/kg
