1. Introduction
The medical device is a Personal device for CARDiac activity (PCARD), named and referenced as
SAVVY in the remainder of the document. The SAVVY medical device constitutes from a as Savvy
sensor, charger, charging dock and mobile application (MobECG). The core of the system is a
small and light (21g) Savvy sensor, fixed to the skin using standard self-adhesive electrodes. The
Savvy sensor measures the user's differential ECG between two proximal electrodes on the
distance of approx. 8,5 cm. The moderate resolution ECG is suitable for long-term personal
cardiac activity monitoring during every-day or sport activities, and for clinical use. With a single
charge of the built-in battery, the Savvy sensor can run continuously for up to seven days and
at least 14 days in stand-by mode. The SAVVY sensor can be recharged using a charging dock
station that comes with it. The measurements from the Savvy sensor are transferred through a
build-in low power Bluetooth BT4.0 radio to the mobile application on a personal digital
assistant (PDA), i.e. smartphone or tablet, which provides storage and graphical presentation
of the measurements. User can be a healthy person, person under screening or a patient. The
usage of the MD is not limited by age, sex, body weight or height and other personal
characteristics.
A Patient can generate ECG REPORT on mobile device in PDF format, which can be printed out
or sent by e-mail to the patient Doctor for further diagnose.
