Cardiac Arrhythmia Telemetry; Conventional vs HeartWatch
- Conditions
- Cardiac ArrhythmiaDiagnostic/Monitoring Devices Related to Adverse Incidents
- Interventions
- Device: HeartWatch
- Registration Number
- NCT06164808
- Lead Sponsor
- HelpWear Inc.
- Brief Summary
Heart rhythm disorders are common and significantly impact the lives of those affected and their families. The main problems can be categorized as: a) atrial fibrillation or AF and atrial flutter, b) supra-ventricular tachycardia or SVT, c) excessively slow heart beats (i.e., bradycardia or pauses) and d) ventricular arrhythmias. These problems can be difficult to detect with currently available monitoring options as they are all worn for shorter terms or are an invasive implantable option. The HeartWatch is a longer term monitoring system that is worn on the upper arm, allows users to create a tag and pairs with an app on a smartphone allowing for correlation of symptoms.
- Detailed Description
Patients who are being referred to wear a holter monitor will be approached to wear a HeartWatch simultaneously. This will allow collection of signals on both devices and to compare the accuracy of signals between the Heartwatch vs Holter monitor. It will also examine the reliability of autodetect algorythms between the devices. We will also collect information to compare the amount of adverse events between the various systems and the patient preference of those systems.

- Arm && Interventions
Group Intervention Description Active device engagement HeartWatch All subjects will wear either the Holter monitor and the HeartWatch.
- Primary Outcome Measures
Name Time Method QRS signal detection For the duration of time that the patient wears the Holter monitor and the HeartWatch, 24-48 hours Compare QRS detection accuracy with HeartWatch data vs. the Holter monitor lead I signal
- Secondary Outcome Measures
Name Time Method ECG PR interval assessment For the duration of time that the subject wears the holter vs the HeartWatch (24-48 hours). Assess the comparability of paired, 10-minute averaged PR intervals measured from the HeartWatch vs. the Holter lead I reference signal.
ECG QRS interval assessment For the duration of time that the subject wears the holter vs the HeartWatch (24-48 hours). Assess the comparability of paired, 10-minute averaged QRS intervals measured from the HeartWatch vs. the Holter lead I reference signal.
ECG strip evaluation For the duration of time that the subject wears the holter vs the HeartWatch (24-48 hours). Compare the overall agreement of the HeartWatch vs. Holter data in providing interpretable ECG strips data for all symptomatic (patient tagged) events and all cardiologist-verified non-normal rhythms identified by cardiology technologists (Holter).
ECG interval assessment For the duration of time that the subject wears the holter vs the HeartWatch (24-48 hours). Assess the comparability of paired, 10-minute averaged heart rate corrected QT (QTc) intervals measured from the HeartWatch vs. the Holter lead I reference signal.
