VENTRICULAR FIBRILLATION

This study tests a new way to restart the heart in people who have a cardiac arrest outside the hospital and don't respond to the first shock. It compares using two defibrillators in different positions versus the standard single defibrillator. The goal is to see if the double ap…

This study tests if cooling people quickly after a cardiac arrest (when the heart stops) can help them survive with full brain function. About 1,022 adults aged 18-79 who have a shockable heart rhythm will be included. Half will get rapid cooling through the nose by emergency wor…

This study looks at whether giving a lower total amount of epinephrine during resuscitation from cardiac arrest helps more people survive to leave the hospital. About 3,790 adults whose heart stops due to a shockable rhythm will be randomly assigned to receive either a low or sta…

This study is testing whether a sedative medication called dexmedetomidine can help control a life-threatening condition called 'electrical storm,' where the heart's lower chambers beat dangerously fast and repeatedly. About 192 adult patients in intensive care units with this co…

This study looks at whether placing a balloon in the main artery (aorta) during CPR can help blood flow to the heart and brain in people who have a cardiac arrest outside the hospital. It involves 40 adults aged 18-80 with no major injuries. The goal is to see if the procedure is…

This study watches how a left bundle branch pacing lead records heart signals in 50 people who already have an ICD or CRT-D device. Researchers want to see if the lead gives clear, stable readings during daily activities and fast pacing. The goal is to improve detection of danger…

This study aims to improve how we detect and understand heart disease using advanced MRI scans. Researchers will compare new MRI techniques with standard tests in 1,000 adults, both healthy volunteers and those with various heart conditions. The goal is to find better ways to see…
