  Electrocardiogram

Introduction to Electrocardiogram: Electrocardiography: Principle:

It is an instrument that records the heart's electrical activity. It gives information regarding to cardiac disorders. It is employed in coronary care units, catheterization, and diagnostics applications. Low frequency range is necessary to make sure stability of baseline. High frequency response is a compromise of various factors such as isolation among a helpful ECG signals from other signals. Baseline's Instability, originating from the changes of the contact impedance demands the application of automatic baseline stabilizing circuit.

Description:

The potentials picked up through the patient electrodes are occupied to the load selector switch. Through the capacitive coupling the signal is connected symmetrically to the long tail pair differential pre-amplifier. The pre-amplifier is a 4 stage differential amplifiers. And after that the amplified output signal is picked up single ended and provided to power amplifier. The output of power amplifier is single ended and delivered to pen motor. Frequency selective network is an R-C network. The stylus moved in reply to input signal but paper is stationary.

PROCEDURE:

1. The leads are placed in legs and arms.

2. Squeeze the ECG gel into the skin at the selected location and rub so that little reddening happens.

3. Clip on limb node to patient table to correspond electrode preventing to markings given by electrode lead wires.

4. Press ON or OFF button.

5. Test lead will light up pointing out power is ON. Adjust stylus to the centres.

6. Press start and the paper starts moving.

7. Press 1 mv and after that adjust stylus temperature. Select lead position.

APPLICATION:

For identify cardiac disorder.
