New pacemaker approach could reduce heart failure risk
Disease control Recruiting nowThis study compares two pacemaker methods for people with a slow heart rate: standard right ventricular pacing and a newer 'physiological pacing' that targets the heart's natural conduction system. Researchers will track 2,600 participants over time to see which method better pre…

New pacemaker promises longer battery, better heart rhythm
Disease control Recruiting nowThis study tests a new, smaller pacemaker called Micra AV2 in 150 adults with heart block (a condition where the heart's electrical signals are blocked). The pacemaker is designed to better match the heart's natural rhythm, especially during exercise, and lasts over 15 years. Res…

New heart procedure could replace pacemakers for fainting patients
Disease control Recruiting nowThis study is tracking 300 people under age 60 who faint frequently due to a condition called vasovagal syncope. Participants will receive either a nerve ablation procedure (which targets heart nerves) or a permanent pacemaker. The goal is to see which treatment better prevents f…
