BRADYCARDIA

This study tests the safety and performance of a new pacemaker system (Amvia pacemaker and Solia CSP S lead) for people who need help with their heart's electrical system. The device is designed to pace a specific part of the heart's natural wiring to improve efficiency. 152 part…

This study tests a new pacing lead (Solia CSP S) placed deep in the heart to treat slow heart rhythms. About 192 people with heart block or sinus node problems will get the lead. The main goals are to check safety (no serious device issues in 3 months) and how often the lead is p…

This study is testing a new type of pacemaker that doesn't use wires (leads) to help control slow heart rhythms. About 20 adults who need a pacemaker will get this device and be checked for safety and how well it works at 1 and 3 months. The goal is to see if this leadless system…

This pilot study tests whether increasing the backup pacing rate from 75 to 100 beats per minute improves heart function in adults with cardiogenic shock and a permanent pacemaker. Twenty-five participants in the cardiac ICU will be exposed to both rates in random order, with hea…

This study follows over 3,400 people who have already received the Aveir VR leadless pacemaker to check its long-term safety. Researchers are tracking complications up to 10 years after the device is implanted. The goal is to make sure this small, wire-free pacemaker works safely…

This study follows about 37,000 Medicare patients who received a Micra leadless pacemaker to treat slow heart rate (bradycardia). Researchers use insurance claims data to check for complications within 30 days and survival rates over two years. The goal is to meet a government re…

This study looks at 80 women having breast cancer surgery to see if using a mix of two numbing medicines (levobupivacaine and lidocaine) for a nerve block causes more changes in blood pressure and heart rate than using just one (levobupivacaine alone). The goal is to find which a…

This study gathers information from 1,000 adults who have or will receive a cardiac implantable electronic device (CIED) for heart rhythm problems like bradycardia or tachycardia. Researchers collect details about the device, the implant procedure, and patient characteristics to …

This study follows about 3100 people who receive a Micra pacemaker to treat slow heart rate (bradycardia). Researchers want to see how safe and effective the device is in routine medical practice, not just in controlled trials. Participants are monitored for complications and dev…

This study follows 37,000 Medicare patients who received a Micra AV leadless pacemaker or a traditional pacemaker to treat slow heart rate (bradycardia). Researchers will compare complication rates and survival over two years using insurance claims data. The goal is to understand…
