1 Product Introduction
1.1 Introducing S-Patch Ex
The S-Patch Ex is a light-weight electrocardiogram (ECG) and heart rate (HR) monitoring
device with accompanying software. The S-Patch Ex operates wirelessly, and due to its
compact size it is unobtrusive during daily activity. The S-Patch Ex continuously measures
ECG and HR signals, and streams the digitized signals to a mobile gateway device equipped
with S-Patch Ex App. At the end of each ECG recording session, patients can upload their
data to a secure cloud portal via their mobile device connection. After the data upload
takes place, physicians can access and review their patients’ ECG data remotely via the S-
Patch Ex Web. The S-Patch Ex is intended to be used with direction from trained medical
professionals in accordance with the user manual.
