Atrial flutter

This study follows 2000 people who have or will get the OmniaSecure defibrillation lead, a wire that helps control dangerous heart rhythms. Researchers will track how often the lead causes problems over 5 years. The goal is to make sure the lead is safe and works as expected in e…

This trial investigates whether pulsed field ablation (PFA) can safely isolate the pulmonary veins in adults with congenital heart disease who experience atrial tachycardia. Participants will undergo PFA during a standard ablation procedure. The study measures how well the veins …

This study is tracking 100 adults who receive an EluPro antibiotic-eluting envelope during implantation of a heart device (like a pacemaker). The envelope slowly releases antibiotics to prevent infection. Researchers are monitoring complication rates in real-world use to see how …

This Phase 2 trial tests JK07, a lab-made protein designed to help heart cells repair and pump better. About 282 adults with chronic heart failure will receive either JK07 or a placebo. The study looks at safety and whether JK07 can improve heart function in two groups: those wit…

This study tests whether a new drug called Refralon, taken as a tablet once or twice daily, can prevent atrial fibrillation or flutter from returning after normal heart rhythm has been restored. About 175 adults with persistent AFib will receive either Refralon or a placebo for 6…

This study tests whether a computer alert in doctors' charts can help more atrial fibrillation patients get blood thinners to prevent strokes. About 5,094 patients and their doctors are involved. The alert fires during visits if a patient has high stroke risk but isn't on blood t…

This study tests a new type of heart ablation called pulsed-field ablation for people with a recurring heart rhythm problem called atypical atrial flutter. The goal is to see if this method is safer and works better than standard treatments. About 30 adults will receive the proce…

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 was designed to test a new portable ECG recorder called Hativ P30, which uses artificial intelligence to analyze heart rhythms. Researchers planned to compare its readings to a standard 12-lead ECG in adults, including those with and without arrhythmias. However, the s…

This study aims to better understand atrial fibrillation (AFib), the most common abnormal heart rhythm. Researchers will use mobile devices like ECG patches and a smartphone app to monitor heart rhythm, activity, and sleep in 3,000 adults, some with AFib and some without. Partici…

This registry follows 545 people with arrhythmia who received a heart ablation using the DiamondTemp system. Researchers will track how many stay free of their heart rhythm problem and how many have serious side effects over 12 months. The goal is to see how well the device works…

This study tests whether watching storytelling videos can help African American and Black patients with atrial fibrillation (an irregular heartbeat) start and continue taking blood thinners to prevent strokes. About 80 adults who are not currently on blood thinners but have a hig…

This observational study is tracking 1,000 patients with stable atrial tachycardia to see how well different rhythm control treatments work over the long term. Researchers are focusing on serious outcomes like death, stroke, and heart-related hospital stays. The goal is to gather…
