Do you know about electrocardiograms and electrode pads?

     ECG/EKG is a graphical report generated by a device that records the rhythmic electrical activity of the heart. Each time the heart contracts and relaxes, cardiac muscle 

cells produce weak electrical signals, which are conducted through body tissues to the skin surface. An ECG machine captures these signals using specific equipment, 

converts them into visual waveforms, and doctors use these waveforms to assess whether the heart's rhythm,conduction function, and myocardial blood supply are normal.

    Electrodes is "signal-capturing components" attached to the body's surface to capture cardiac electrical signals. Cardiac electrical signals can't be directly recognised by 

the ECG machine; they must be captured by electrode placed at specific locations on the body's surface to capture the signals, which are then transmitted to the ECG

machine via wires.

    Electrode is the "foundation of signals" for ECG, and ECG is the "final manifestation"of electrode functionality. Together, they complete the detection and recording of

 cardiac electrical activity.
