Atrial flutter
MONDO:0005310A disorder characterized by an electrocardiographic finding of an organized, regular atrial rhythm with atrial rate of 240-340 beats per minute. Multiple P waves typically appear in the inferior leads in a saw tooth-like pattern between the QRS complexes. (CDISC)
Also known as: atrial flutter, atrial flutter (disease)

Could a preventive ablation during flutter treatment ward off future heart trouble?
Disease control Not yet recruitingThis 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…

Can a blood thinner cut stroke risk in dialysis patients?
Disease control Not yet recruitingThis trial tests whether apixaban, a blood thinner, can reduce the risk of stroke or blood clots in adults on dialysis who also have atrial fibrillation (an irregular heartbeat). Participants are randomly assigned to receive either apixaban or no oral anticoagulant, while continu…

Smart pacemaker aims to catch and stop heart flutter before it starts
Disease control Not yet recruitingThis 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…

New pacing method may offer drug-free relief for dangerous rapid heartbeats
Disease control Not yet recruitingThis 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…

Your voice may soon detect hidden heart trouble
Diagnosis Not yet recruitingThis 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…

Smart alerts aim to slash stroke risk in heart patients
Prevention Not yet recruitingThis 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…

One-Doctor sedation could speed up heart treatment
Symptom relief Not yet recruitingThis 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…

Could a simple mineral tame a racing heart? new trial tests magnesium for AFib
Symptom relief Not yet recruitingThis 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…

Which shock strength works best for AF? new trial aims to settle the debate
Symptom relief Not yet recruitingThis 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…
