Cardiac Arrhythmia Telemetry; Conventional vs HeartWatch

Recruiting now NCT06164808

Run by HelpWear Inc. · for 22 and older · All sexes

What this study is about

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.
