Surface ECG Mapping in Healthy Adult Volunteers
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study aims to confirm a scientific concept that superficially placed electrocardiogram (ECG) leads may be compared to one another to help determine positioning. If proven to be effective, this could offer a more non-invasive means of positioning using superficial ECG tracings.
