1.2 General Description
The ECG Mini system consists of 3 main components:

Disposable 1-lead patch with ECG electrodes

Reusable processing and transmitter device, also called
“Brain”

Gateway cellular device
The 1-lead ECG patch contains 3 electrodes which are used for
1-lead arrhythmia detection. The 1-lead patch ECG is attached to
the upper chest of the body.
The 1-lead patch contains 3 ECG electrodes, a cradle for the Brain
and one coin battery for powering the Brain.
The 1-lead patch is a disposable part which is mounted on the
patient body throughout the service period. Special slot within the
patch enables easy insertion of the brain to its cradle by the user.
The brain receives its power from a 1.4V coin non-rechargeable
battery integrated within the patch.
The brain transmits ECG raw data to the Gateway cellular device
wirelessly using unique RF protocol. In addition, the Brain contains a
32MB Flash memory chip that can store 6 hours of data in case of
communication failure with the Gateway cellular device.
The Gateway cellular device is located in the patient home and
receives the ECG signs data from the Patch wirelessly over a unique
RF protocol. The Gateway cellular device analyzes the ECG data
and generates events which reflect 4 arrhythmias
– Pause, AFIB,
Tachycardia and Bradycardia. These events are transmitted to the
monitoring center backend system of LifeWatch Services over
