Brief summary

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.

Interventions

The HeartWatch arm band provides continuous, high-quality single lead electrocardiograph (ECG) data in a variety of environments. The ECG data is transmitted via Bluetooth and stored on the user's smartphone. It is then uploaded to the cloud for subsequent analysis using either a commercial ECG software package or a customized software package from HelpWear.

DEVICEEvent Recorder

A standard 1 or 2-lead Sirona Event Recorder will be used to collect high-resolution data. Subjects will be asked to wear the clinical monitor for at least 48 hours and no longer than 84 hours. ECG signals will be continuously collected as long as the skin patches are attached to the skin and the recorder is properly connected to the wires.

A standard 5-lead SEER Holter will be used to collect 3-channels of high-resolution data. Subjects will be asked to wear the clinical, conventional monitor for at least 36 hours and no longer than 60 hours. During this time ECG signals will be continuously collected.
