Atrial flutter

This study tests whether adding a preventive procedure called pulmonary vein isolation (PVI) to the standard ablation for typical atrial flutter can reduce the risk of heart-related hospital visits, stroke, or death. The trial enrolls adults aged 55 and older with an enlarged lef…

This study follows 30 adults with paroxysmal atrial fibrillation (PAF) who have or will get a special pacemaker. The pacemaker can detect irregular heartbeats early and send a painless pacing pulse to stop them. It also sends data to doctors remotely. Researchers will check how w…

This study tests a temporary pacing technique to slow dangerously fast heart rates in people with atrial fibrillation who cannot use standard medications. Researchers will pace specific nerve fibers near the heart to see if it safely controls heart rate without permanent procedur…

This study tests a new technology that listens to your voice during short phone calls to detect atrial fibrillation, a common heart rhythm problem. Researchers will enroll 40 adults scheduled for a heart reset procedure (cardioversion) and compare voice recordings with standard h…

This study tests whether an electronic alert in doctors' computers can increase the use of blood thinners to prevent strokes in people with atrial fibrillation (an irregular heartbeat). About 2,500 high-risk patients who are not currently on blood thinners will take part. The goa…

This study compares two ways to sedate patients during a heart scan and electric shock treatment for atrial fibrillation. Currently, a cardiologist gives mild sedation for the scan, but an anaesthesiologist must give stronger sedation for the shock, causing delays. Researchers wa…

This study tests whether giving magnesium along with the standard drug metoprolol can quickly lower a dangerously fast heart rate in people with atrial fibrillation or atrial flutter. About 196 adults in the emergency room will receive either magnesium or a placebo, plus metoprol…

This study tests whether starting with a higher shock energy (360 J) is better than a standard 200 J for restoring normal heart rhythm in people with atrial fibrillation. About 400 adults will be randomly assigned to one of three groups, including a personalized approach based on…

This study follows 25,000 people referred to a specialized heart clinic with symptoms like chest pain or shortness of breath. Researchers will track which heart conditions are actually diagnosed and how patients are evaluated. The goal is to improve diagnostic accuracy and unders…

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 looks at whether people with certain heart rhythm disorders also carry genetic variants linked to a rare muscle condition called non-dystrophic myotonia. Researchers will review medical records of 570 participants and invite some for a neurological exam and electromyog…
