This study tests whether using an insertable heart monitor to guide early treatment can reduce the amount of time people spend in atrial fibrillation (AFib) after a catheter ablation. About 120 adults with AFib will get the monitor before or during their ablation procedure. The g…

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 older adults with heart block. The goal is to see if the leadless version works as well for exercise capacity. Both devices control heart rhythm, but the leadless one avoids wires …

This study looks at whether a new, non-invasive ultrasound imaging technique called electromechanical wave imaging (EWI) can help doctors better pinpoint the source of heart rhythm problems before a procedure. About 322 adults already scheduled for a heart rhythm study will get a…

This study checks if a special blood pressure monitor (BPM Core) can correctly detect atrial fibrillation, a common heart rhythm issue, by comparing its readings to a standard 12-lead ECG. About 160 adults aged 18 and older will take part. The goal is to see how well the device's…

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 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 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 aims to find out if 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 from 58 participants, including those with POTS and healthy con…
