Interactive ECG Machine — Working Principle
This interactive educational simulation demonstrates how an ECG machine records the electrical activity of the heart using electrodes, signal amplification, filtering, and waveform display.

1) Electrical Activity of the Heart
The sinoatrial (SA) node generates electrical impulses that spread through the heart muscle.
2) Electrode Placement
Electrodes attached to the body detect tiny voltage differences produced during cardiac activity.
3) Signal Amplification
The ECG machine amplifies weak cardiac electrical signals for accurate recording.
4) Signal Filtering
Noise and electrical interference are removed using electronic filters.
5) ECG Waveform Display
The processed signal is displayed as P waves, QRS complexes, and T waves.
