PORTABLE ELECTROCARDIOGRAM MONITORING DEVICE
First Claim
1. A portable electrocardiogram monitoring device, comprising:
- at least two electrode lead patches; and
an internal circuit capable of receiving an analog signal provided by the at least two electrode lead patches, and the internal circuit consisting of;
a power supply module including a low-noise voltage stabilizing circuit and a voltage regulation circuit, and the low-noise voltage stabilizing circuit having an independent first ground plane, and the voltage regulation circuit having an independent second ground plane; and
a data transmission module including an operational amplifying circuit and a data processing circuit, and the operational amplifying circuit having an independent third ground plane, and the data processing circuit having an independent fourth ground plane, wherein the power supply module supplies power to the data transmission module, so that the analog signal is amplified by the operational amplifying circuit and transmitted to the data processing circuit to generate a digital signal as required by an electrocardiogram;
wherein the independent first, second, third, and fourth ground planes are connected with one other only by a ground channel.

Abstract
A portable electrocardiogram monitoring device comprises a case, at least two electrode lead patches, and an internal circuit provided inside the case for receiving a signal from the at least two electrode lead patches. The internal circuit comprises a power supply module and a data transmission module. The power supply module comprises a low-noise voltage stabilizing circuit having an independent first ground plane and a voltage regulation circuit having an independent second ground plane. The data transmission module comprises an operational amplifying circuit having an independent third ground plane and a data processing circuit having an independent fourth ground plane. And, the independent ground planes are connected with one another only by a ground channel.
