ClinConnect Summary

This clinical trial is looking at whether a smartwatch can detect heart rhythm problems (called arrhythmias) better than a traditional Holter monitor, which is a device worn for 24 hours to record the heart's activity. Sometimes, arrhythmias do not occur every day, making it hard for the Holter monitor to catch them. The trial aims to see if using a smartwatch that records heart rhythms over four weeks can provide more accurate results for people who experience symptoms like palpitations, dizziness, or pre-syncope (feeling faint).

To participate in this study, you need to be between 18 and 80 years old and have been referred for a Holter exam due to specific symptoms. However, if you already have a diagnosis for your symptoms, have a primary symptom of fainting, or cannot follow the recording instructions, you won't be eligible. If you join the trial, you'll wear a smartwatch that tracks your heart activity, and researchers will compare the results with those from the Holter monitor. This study is important because it could lead to better ways to detect heart rhythm issues, ultimately helping more patients receive timely and accurate diagnoses.
