Monitoring suspected heart rhythm issues with Hativ ECG
This study uses a portable Hativ® ECG patch to monitor your heart at home for up to 14 days, aiming to catch irregular rhythms that a single office EKG might miss. It's for people with suspicious symptoms (like palpitations or dizzy spells) who haven't gotten a clear diagnosis yet.
Gwangju, Dong-gu Jaebongro 42Ages 19 years+ - NCT04437914Recruiting
Tests a smartwatch to spot heart rhythm and wiring problems
This study checks how accurately a smartwatch can detect heart rhythm and electrical “wiring” problems compared with a standard heart test. If it works well, it could help make heart monitoring easier and more accessible.
Teresina, PiauíAges 18 years+ - NCT04521790Recruiting
Biopsy-guided treatment for suspected inflammation of the heart
This study looks at people 18 and older with suspected myocarditis (inflammation of the heart). It uses an inner-heart biopsy and tailored treatment based on the likely cause to improve diagnosis and care, especially for people with different heart rhythm or non-rhythm symptoms.
Milan, MilanoAges 18 years+ - NCT04843683Recruiting
Stereotactic radiation treatment for abnormal heart rhythms
This trial studies using a precise type of radiation (stereotactic ablative radiotherapy) to treat abnormal heart rhythms when medicines or prior procedures haven’t worked. It may help by targeting the heart area causing the rhythm problem without doing another invasive ablation.
Toronto, OntarioAges 18 years+ - NCT04844801Recruiting
Prevent fast heart rhythms during sepsis shock with rate control drugs
This trial tests whether a heart-rate–controlling medication can better manage a new fast heart rhythm that happens during sepsis shock. It may help reduce heart strain and improve safety compared with standard care.
ParisAges 18 years+ - NCT05239364Recruiting
Ablation for an abnormal heart rhythm after prior AF surgery
This trial tests a procedure to “ablate” (treat) a specific fast heart rhythm in the upper chambers of the heart that happens after previous atrial fibrillation (AF) ablation or heart surgery. It may help by stopping the rhythm and reducing symptoms, while doctors check how well the targeted mapping and ablation work.
Hamburg, Free and Hanseatic City of HamburgAges 18 years+ - NCT05439031RecruitingPhase 2
Stereotactic radiation to reduce recurrent dangerous heart rhythm episodes
This Phase 2 study tests a precise form of radiation therapy to control recurrent ventricular tachycardia (VT), a dangerous fast heart rhythm. It may help people whose VT keeps coming back despite heart medicines and/or ablation, especially when ablation is not possible.
Amsterdam, North HollandAges 18 years+ - NCT05631730RecruitingPhase 3
Flecainide plus metoprolol vs metoprolol alone for rhythm control
This trial studies whether adding flecainide to metoprolol can better reduce dangerous heart rhythm problems in people with mitral valve prolapse. It also checks safety and side effects compared with metoprolol alone.
OsloAges 18 years+ - NCT05662293Recruiting
Study of heart muscle weakness caused by abnormal heart rhythms
This study looks at a condition where an abnormal heart rhythm can weaken the heart muscle (arrhythmia-induced cardiomyopathy). You may be asked questions, have heart tests reviewed, and help researchers better describe who is affected and how it develops.
BaselAges 18 years+ - NCT05724121Recruiting
Study heart rhythm changes during BTK or venetoclax treatment
This observational study tracks how your heart rhythm (heartbeat pattern) changes while you take a BTK inhibitor or venetoclax. It may help doctors better understand heart rhythm risks in people receiving these cancer-related medicines.
