This study tests whether using a portable heart monitor for 15 days after a fainting episode can detect dangerous heart rhythms that standard short-term monitoring might miss. About 580 adults who fainted and are at medium or high risk will be randomly assigned to either usual ca…

This study tests an artificial intelligence program that analyzes heart rhythm data from a small, wearable patch to estimate how well the heart pumps blood. Researchers will compare the AI's results to standard ultrasound in 2,000 adults. If accurate, this could offer a simpler, …

This study looks at whether carbonated water can help people stay steady on their feet and avoid fainting. Drinking water is known to raise blood pressure, but researchers want to see if the bubbles in carbonated water add an extra benefit by stretching the stomach. 25 healthy ad…

This study looks at whether keeping low- and intermediate-risk fainting patients in the hospital for 24 hours with a heart monitor is better than sending them home right away. About 640 adults will be randomly assigned to either stay or go home. The goal is to see if the longer m…

This study looks at whether certain medications known to affect the heart's electrical activity (QT-prolonging drugs) actually cause major heart problems in hospitalized adults. Researchers will analyze data from over 990,000 patients across Ontario hospitals, comparing those who…

This study watches how well a small heart monitor (BIOMONITOR III) works in routine medical care for 1400 people. It tracks how quickly the device finds hidden heart rhythm problems like atrial fibrillation or fainting spells. The goal is to learn about the device's real-life per…

This study from Mayo Clinic looks for genetic heart conditions in people with epilepsy that might raise the risk of sudden unexpected death (SUDEP). Researchers will analyze DNA from 600 adults aged 18-50 with epilepsy or related symptoms, plus their blood relatives. The goal is …
