Evaluation of Electrocardiographic Measurements by High Density Electrode ECG for Ventricular Arrhythmias

What this Trial Is About

This research aims to improve the detection of cardiac electrical activity by comparing a new high-density ECG method with the conventional 12-lead ECG. The study focuses on patients with ventricular arrhythmias or related heart conditions and explores whether using 128 body surface electrodes can provide more detailed information about heart activity than the standard 12 leads. This could help identify electrical patterns associated with severe ventricular arrhythmias or impaired ventricular conduction. Participants will undergo two types of ECG recordings performed at the same time: the experimental high-density ECG using 128 electrodes placed on the body surface and the standard 12-lead ECG using a subset of these electrodes plus limb electrodes. The high-density ECG involves applying strips of electrodes with adhesive tape and conductive gel, with recordings lasting between 10 to 30 minutes. This simultaneous recording allows comparison of electrical signals captured by both methods. During the study visit, researchers will measure various electrical criteria from the high-density ECG, including amplitude, cardiac timing, duration, and anatomical locations of heart signals. These measurements aim to provide more detailed cardiac information for patients. Participants may be monitored for safety and undergo assessments relevant to their heart condition. The total participation time covers the ECG procedure and associated evaluations on the study day.
