Incessant infant ventricular tachycardia

This study compares two types of portable heart monitors in people who have symptoms of an irregular heartbeat (arrhythmia) but whose standard heart test was normal. About 588 participants will wear either a continuous ECG patch or use a handheld ECG device for one month. The goa…

This study evaluates a new multichannel ECG system designed to detect early signs of cardiovascular disease (CVD) in people who may have no symptoms yet. The system uses advanced algorithms to analyze electrical signals from the heart, looking for subtle abnormalities that could …

This study tests a modified imaging catheter (ViewFlex X ICE) to help doctors see heart structures during procedures for irregular heartbeats. About 500 adults who are already scheduled for a heart procedure using ultrasound will be enrolled. The goal is to see if the new cathete…

This study looks at how a child's quality of life changes after a procedure called transcatheter ablation, which treats abnormal heart rhythms. Researchers will ask 200 children aged 5 to 17 and their parents to fill out questionnaires about physical, emotional, social, and schoo…

This study will observe 253 adults with heart rhythm problems who are scheduled for procedures like pacemakers or ablation. Researchers will use advanced imaging and AI tools to understand why some patients respond well to treatment while others do not. The goal is to find better…

This study will collect ECG recordings from 600 people using the HeartBeam 3-Lead ECG recorder. The goal is to build a database of heart rhythm information for future research and regulatory use. Participants will have their ECG taken as part of routine care, and their de-identif…

This study aims to improve how doctors predict the risk of sudden cardiac death or heart failure in people with inherited heart diseases. Researchers will use artificial intelligence to analyze data from 1,000 participants, including medical history, ECGs, imaging, genetic tests,…

This study looks at whether MRI scans can help predict serious heart events in people who have implanted heart devices like pacemakers or defibrillators. Researchers will scan 1,500 adults before they get their device and track their health for years. The goal is to see if MRI fi…

This study is testing a special heart monitor, the BIOMONITOR IV, in 300 people with heart failure who also have irregular heartbeats. The device tracks heart activity, fluid levels, and breathing patterns to see if it can predict when heart failure gets worse. Researchers hope t…
