BRADYCARDIA

This study compares a standard pacemaker method (right ventricular pacing) with a newer method (physiological pacing) in 2600 people with slow heart rates. The goal is to see which approach better prevents death or heart failure. Participants are randomly assigned to one of the t…

This study looks at how safe and effective a new pacemaker lead is when placed in a specific area of the heart (left bundle branch area) to help people with bradycardia (slow heart rate). About 140 people who need a new pacemaker will be followed to see if the lead works well and…

This study is testing a new way to program pacemakers to help lower blood pressure in people who have both high blood pressure and a slow heart rate. About 30 adults who already have or need a special pacemaker will try two different setup sessions for the new programming. Resear…

This study tests a new leadless pacemaker, the LivIQ, for people with slow heart rhythms like bradycardia or heart block. About 325 adults who need a ventricular pacemaker will get the device. Researchers will check if it works safely and well over 3 months, including how it keep…

This study looks at a new way to pace the heart called left bundle branch area pacing (LBBAP) for people with conditions like slow heartbeat, heart failure, or atrial fibrillation. About 200 adults will get a special pacemaker lead, and researchers will track safety issues like i…

This study tests a new device called UHF-ECG that measures the heart's electrical signals in more detail than a standard ECG. It aims to see if it can better detect when the heart's lower chambers are not pumping together (ventricular dyssynchrony) in 360 adults with slow heartbe…

This study compares two ultrasound-guided nerve blocks (supra-inguinal and infra-inguinal fascia iliaca blocks) to see which one makes it easier for patients to get into position for spinal anesthesia and provides longer pain relief after thigh or knee surgery. Sixty adults aged …

This study compares two types of ultrasound-guided nerve blocks (S-FICB and PENG) to see which one better reduces pain when patients with a broken femur need to sit up for spinal anesthesia. About 70 adults aged 20-70 will take part. The goal is to make positioning less painful a…

This study compares two drugs, dexmedetomidine and dexamethasone, added to a standard numbing medicine (ropivacaine) for arm surgery. The goal is to see which one helps the numbness start faster and last longer. About 66 adults having upper arm surgery will take part. The results…

This study looks at whether playing womb-like sounds to preterm infants can help their brains mature and improve breathing control. Researchers will monitor 34 babies born at 29-33 weeks for breathing pauses, low oxygen, and slow heart rate. The goal is to understand how sound af…

This study is observing 1400 people who get a small heart monitor implanted under their skin. The monitor watches for irregular heartbeats like atrial fibrillation or slow heart rate. Researchers want to see how quickly the device finds these problems and how easy it is to insert…

This study will follow 1000 people with a slow heartbeat (bradycardia) who already have a specific type of pacemaker. The pacemaker will track sleep-related breathing problems and daily activity to see if these can predict future heart attacks, strokes, or irregular heart rhythms…

This study is for people with a slow heartbeat (bradycardia) or heart failure who are already scheduled to get a pacemaker or similar device. Researchers will take extra measurements during the implant procedure to see how a special type of pacing called His bundle pacing affects…

This study tests a portable ECG system to help doctors monitor a specific type of heart pacing (left bundle branch area pacing) during pacemaker or defibrillator implantation. About 55 adults who need this pacing will participate. The goal is to see if the portable ECG works as w…

This study looks at electrical signals in the heart during different pacing strengths and body positions in 75 adults who already have a special type of pacemaker called LBBAP. The goal is to gather data that could help create a smarter algorithm to detect when the pacemaker is c…

This study is observing how well Medtronic heart devices (like pacemakers and defibrillators) work over time in 20,000 people with heart rhythm problems or heart failure. Researchers are tracking device survival and complications to improve future products. Participants must alre…
