Atrial flutter

This trial tests whether a wearable ECG patch called MEMO Patch Plus can detect clinically significant arrhythmias in adults hospitalized with acute heart failure. Participants wear the patch for up to 14 days in the hospital and again for up to 14 days after discharge. The study…

This early-stage trial is testing an investigational drug called SHR-2004, given as multiple injections under the skin, in about 10 adults with atrial fibrillation (an irregular heartbeat). The main goal is to see if the drug is safe and tolerable, and to learn how it moves throu…

This study tested two different catheters (lattice-tip vs standard irrigated-tip) for a heart procedure called ablation, which treats a fast heartbeat (atrial flutter). 102 adults received the procedure to see which catheter works better and faster with fewer side effects. The go…

This study followed 364 people with paroxysmal atrial fibrillation (a type of irregular heartbeat) who had already received ablation treatment in a previous trial. Researchers compared a newer pulsed field ablation system with traditional thermal ablation to see how well each met…

This study tested a device called the Lariat to close off a small pouch in the heart (the left atrial appendage) in people with atrial fibrillation who cannot take blood thinners. The goal was to reduce the risk of stroke. Nine participants were enrolled, and the study measured h…

This study tested a new catheter system that uses pulsed field energy to treat atrial fibrillation and related arrhythmias. In 141 patients, doctors used the VARIPULSE catheter with a 3D mapping system to destroy the heart tissue causing the irregular rhythm. The goal was to see …

This study tested whether giving calcium before the drug diltiazem can prevent a sudden drop in blood pressure in people with a fast heart rate due to atrial fibrillation or flutter. 92 adults took part. The goal was to make the treatment safer and more comfortable.

This study followed 167 people with atrial fibrillation or flutter who had a catheter ablation procedure. Researchers measured changes in stroke and bleeding risk scores before and 3, 6, and 12 months after ablation. They also compared different monitoring methods, including impl…

This study tested a new imaging system called VERAFEYE in 18 people already scheduled for standard heart procedures like ablation or closure. Doctors used the device during the procedure and gave feedback via a questionnaire. The goal was to gather information to improve the syst…
