Premature Ventricular Contractions clinical trials at UCSF

3 in progress, 1 open to eligible people

Premature ventricular contractions are extra beats that happen early in the heartbeat cycle. UCSF is studying how broken sleep may cause a rise in extra beats and other irregular heart signals in the short term. UCSF is collecting data with simple sleep logs and heart monitors.

  • Disrupted Sleep and Concurrent Ectopy or Atrial Fibrillation

    open to eligible people ages 21 years and up

    Whereas the available evidence mostly supports chronic sleep disruption as a risk factor for incident AF, less is known about the near-term risk of a discrete atrial fibrillation (AF) episode following a night of disrupted or poor-quality sleep. This prospective, randomized, case-crossover study aims to examine the acute effects of sleep disruption on clinically relevant cardiac ectopy pertinent to AF.

  • MARY-JANE Cannabis and Heart Rhythm Trial

    Sorry, in progress, not accepting new patients

    Despite recreational cannabis now being legal in 23 states, where more than 100 million Americans reside, studies on the actual health effects are limited. This study is a randomized trial, where each participant will be instructed to consume or avoid cannabis on randomly assigned days during a 14-day monitoring period. The goal of this study is to answer the question: "Does cannabis use increase the frequency of 'early' and abnormal heart beats?" During the 14-day period, participants will wear an external heart monitor, a glucose monitor, and a fitness tracker to track heart rhythm, glucose levels, step counts, and sleep health. Participants will use a mobile app or a text messaging service for daily instructions/reminders on cannabis use, and short surveys. The investigators ask that participants smoke or vape cannabis at least once on days they are instructed to consume cannabis. Compelling evidence of heart and other health effects would be important to the clinical care of our patients.

  • IVTCC 2.0: A Prospective Multicenter Ventricular Tachycardia Catheter Ablation Registry

    Sorry, accepting new patients by invitation only

    This is a prospective multi-center international registry. The objective of this registry is to collect prospective data on patients undergoing catheter ablation for Ventricular Tachycardia (VT) and Premature Ventricular Contractions (PVC). The registry will be used for clinical monitoring, research, and quality improvement purposes.
