Details and patient eligibility

About

The clinical study is intended to implement and test the collection and analysis of paired ECG data from the HeartWatch and two comparator devices, an Event Recorder and Holter. The HeartWatch is indicated for extended diagnostic evaluation of patients with transient symptoms of possible cardiac origin such as syncope and palpitations, as well as patients at risk for arrhythmias, but without significant symptoms. While the use of the device itself can be managed by both healthcare professionals and patients, interpretation of the collected data for diagnosis is restricted to healthcare professionals, as the data must be loaded and analyzed separately after recording. Patients indicated for extended ambulatory ECG testing will be approached for participation. Subjects will wear the HeartWatch and an Event Recorder for up to 72 hours or the HeartWatch and Holter monitor for up to 48 hours. Subjects will be asked to document their activities (standing, sitting, walking, exercise, or laying down). Event recorder subjects will collect user-triggered and auto-triggered data, while Holter subjects will record diary information on their activities and any relevant symptoms. Adverse events and user preference for one device versus the other being used in that arm will also be collected from all subjects. Paired ECG data from the HeartWatch and comparator devices is expected to be similar in terms of the events documented and the proportion of data that is clinically interpretable.
