As shown in FIG. 1, the present invention provides an emergency heart rate machine comprising a housing 3, an electrocardiogram monitoring circuit 16, an electrocardiogram display 12, an electrical pulse circuit 15, and a plurality of lead wires;

The electrocardiogram monitoring circuit 16 and the electrical pulse circuit 15 are disposed in the housing 3;

The electrocardiogram display 12 is disposed on the housing 3;

The ECG monitoring circuit 16 is connected to the electrocardiogram display 12;

The ECG monitoring circuit 16 is connected to at least two lead wires for monitoring a human heartbeat;

The electric pulse circuit 15 is connected to the electrocardiogram display 12;

The electric pulse circuit 15 is connected to the electrocardiogram monitoring circuit 16;

The electric pulse circuit 15 is connected to at least two lead wires for transmitting a pulse current to the human body.

First, the two lead wires of the existing small ECG monitor can be placed on the upper right and lower left of the chest of the human body, and the normal electrocardiographic pulse wave can be detected, so that the simple two lead wires can be verified. It is easy to measure the normal ECG waveform of the human body.

Repeated test with electric pulse meter, the two lead wires of the electric pulse are gradually connected with the two lead wires of the ECG monitor when the discharge pulse is generated, and the input and output parameters of the two circuits are matched with each other and measured. The waveform and the changed shape of the electric pulse signal displayed on the electrocardiograph are verified, so that it can be verified that the electrocardiographic monitoring circuit 16 and the electrical pulse circuit 15 can match each other.

The ECG monitoring circuit 16 and the electrical pulse circuit 15 are combined into one, and the integrated manner is as follows:

A lead wire of the electric pulse circuit 15 is connected to the lead wire of the electrocardiogram monitoring circuit 16 which should be placed on the lower left chest of the patient, and the other lead wire of the electric pulse circuit 15 is independently connected to the output socket, and then added.
