ARRHYTHMIAS, CARDIAC

This study tests a new device that combines two heart therapies: one to strengthen heartbeats and another to stop dangerous rhythms. About 300 adults with heart failure and a weak heart pump will get the device. Researchers will check if it safely converts life-threatening heart …

This study compares a new leadless pacemaker (Micra AV) to a standard dual-chamber pacemaker in 100 patients aged 70 and older with heart block. The goal is to see if the leadless version works just as well for exercise capacity. Participants are randomly assigned to receive one …

This study tests whether using an implantable heart monitor (or a wearable patch) to detect atrial fibrillation early after catheter ablation can reduce the total time spent in AF. About 120 people with paroxysmal or persistent AF will be monitored for 15 months. The goal is to s…

This study tests a new, non-invasive ultrasound method called electromechanical wave imaging (EWI) to see if it can more accurately locate and diagnose heart rhythm problems compared to standard tests. About 322 adults already scheduled for a heart procedure will get an EWI scan …

This study is testing whether a smart blood pressure cuff called the Withings BPM Core can accurately detect atrial fibrillation, a common heart rhythm problem. Researchers will compare the device's single-lead ECG readings to a standard 12-lead ECG in 160 adults. If it works wel…

This study is observing 4,500 people who need pacemakers or similar heart devices. The goal is to create a tool that predicts who is at risk of developing a weakened heart from the device itself. By identifying high-risk patients early, doctors can choose better pacing methods to…

This study follows 186 adults with atrial fibrillation who are having a heart ablation procedure. Doctors use an AI software to guide the treatment, and researchers track how well it works and any side effects over two years. The goal is to see if the AI helps improve outcomes an…

This study gathers information from 1,000 adults who have or will receive a cardiac implantable electronic device (CIED) for heart rhythm problems like bradycardia or tachycardia. Researchers collect details about the device, the implant procedure, and patient characteristics to …

This study at Vanderbilt University Medical Center is looking at whether people with postural tachycardia syndrome (POTS) have higher levels of certain immune proteins that might affect their symptoms. Researchers will measure these proteins in blood samples and test how the hear…
