Using adenosine to understand the causes of premature ventricular contractions

Use of Adenosine to Determine the Electrophysiological Mechanism of Premature Ventricular Contractions

Phase 4 Interventional Weill Medical College of Cornell University · NCT03218137

This study is testing if giving adenosine and verapamil to patients can help doctors understand what causes premature ventricular contractions (PVCs) and how to better treat them.

What this trial studies

This study investigates the electrophysiological mechanisms behind premature ventricular contractions (PVCs) by administering adenosine and verapamil to patients undergoing an electrophysiology study. It aims to determine if these substances can induce PVCs similarly to sustained ventricular tachycardia, thereby shedding light on the cellular mechanisms involved. The study will involve 100 subjects who have consented to participate in this controlled, non-randomized trial. The findings could lead to new therapeutic targets for treating PVCs and related arrhythmias.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 70 diagnosed with premature ventricular contractions who are scheduled for an electrophysiology study.

Not a fit: Patients with structural heart disease, significant coronary artery disease, or those currently on anti-arrhythmic drugs may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights that lead to improved treatments for patients suffering from PVCs.

How similar studies have performed: Other studies have shown success in using adenosine to understand arrhythmias, but this specific approach to PVCs is relatively novel.
