Cardiac arrhythmias

This study looks at people with heart devices that detect short bursts of irregular heartbeats (atrial high-rate episodes lasting 6 minutes to 24 hours) but no diagnosed atrial fibrillation. It tests whether starting rhythm-control drugs early, along with managing heart risk fact…

This study is testing a cloud-based artificial intelligence platform called Willem that analyzes ECG recordings to detect heart rhythm problems and abnormal patterns. Researchers will compare the AI's readings to those of board-certified cardiologists in over 5,300 high-risk card…

This study tests a modified imaging catheter (ViewFlex X ICE) to help doctors see heart structures during procedures for irregular heartbeats. About 500 adults who are already scheduled for a heart procedure using ultrasound will be enrolled. The goal is to see if the new cathete…

Researchers at the Heart Center Bad Berka run a registry that collects data on adults treated for heart rhythm problems. The registry follows people who receive medication, procedures such as ablation, or implanted cardiac devices. It tracks how safe and effective these treatment…

This observational study will follow 8,000 people with irregular heartbeats (arrhythmias) who are scheduled for a standard catheter ablation procedure using Biosense Webster devices. Researchers will track safety issues and how well the procedure works in everyday hospital practi…

This study tests whether artificial intelligence can use continuous ECG data to predict and detect life-threatening heart arrhythmias in patients admitted with acute cardiac illness. Researchers will analyze stored ECG data from 3000 adult patients to see if AI models can forecas…

This study watches people with blood cancers like CLL who take BTK inhibitors or venetoclax to see how these drugs affect heart rhythm. Researchers will use EKGs, stress tests, and heart monitors to track abnormal rhythms and sudden death risk. The goal is to better understand an…

This study will have up to 10,000 adults wear a smartwatch for one year to collect health data like heart rate and activity. Participants will also answer questions through a phone app. The goal is to see if smartwatch data can help doctors spot heart problems earlier. No drugs o…
