New heart lead aims to improve pacing for slow heartbeat
Disease control CompletedThis 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…

Wireless pacemaker shows promise for Dual-Chamber pacing
Disease control CompletedThis study tested a new type of pacemaker that doesn't use wires (leads) to help both the upper and lower chambers of the heart beat in sync. It involved 464 people with slow heart rhythms who needed a pacemaker. The main goals were to see if the device was safe and worked well a…

New pacing technique may shield heart from failure in block patients
Disease control CompletedThis study tested a newer pacing method (left bundle branch area pacing) against the standard method (right ventricular pacing) in 486 adults with atrioventricular block, a condition where the heart's electrical signals are delayed. The goal was to see if the newer method better …

Where you inject matters: study tests best spot for back pain block
Symptom relief CompletedThis completed study looked at 90 people with lower back pain from conditions like herniated discs or spinal stenosis. Researchers compared two different target areas for injecting numbing medicine during a lumbar spine block to see which provides better pain relief and blood flo…

Pacemaker tweak may lower blood pressure in early test
Knowledge-focused CompletedThis small, completed study tested whether special pacing signals from a pacemaker could help control blood pressure in people with slow heartbeats. Five adults who needed a pacemaker or similar device took part. Researchers measured blood pressure and heart function during brief…

Pacemaker tweak may boost heart performance in small study
Knowledge-focused CompletedThis study tested whether individually adjusting the timing (atrioventricular delay) of a pacemaker improves heart function in 39 adults with conduction system pacing. Researchers used echocardiography to optimize settings and measured changes in heart strain, pumping ability, an…
