BRADYCARDIA

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 study tests the safety and performance of a new pacemaker and lead designed to pace the heart's natural electrical system more precisely. It involves 152 people who need a pacemaker for slow heart rate or heart failure. Participants will be followed for at least a year to mo…

This study tracks over 3,400 people who already have an Aveir VR leadless pacemaker to see how safe it is over 10 years. The pacemaker helps control slow heart rhythms. Researchers will monitor for complications shortly after implant and for years afterward.

This study tests a new pacing lead (Solia CSP S) for people with slow heart rhythms. About 192 participants will get the lead placed in a specific area of the heart to see if it is safe and works well. The main focus is on serious side effects within 3 months and how often the le…

This study looks at whether increasing the backup pacemaker rate to 100 beats per minute improves blood flow in adults with cardiogenic shock and a naturally slow heart rate. Participants are already in the cardiac ICU with a permanent pacemaker and a monitoring catheter. Each pe…

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 37,000 Medicare patients who received a Micra leadless pacemaker for slow heart rate (bradycardia). Researchers use insurance claims to check for complications within 30 days and survival rates over two years. The goal is to gather real-world safety data …

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…
