In 1895, the World witnessed two major scientific breakthroughs invention of x-ray by Roentgen and the first electrocardiograph recorded by Willem Einthoven, a Dutch doctor and physiologist. Einthoven went on to name the P, Q, R, S and T waveforms and the Einthoven triangle based on which we calculate the cardiac axis. Refining of the amplification and filtering has led to a clean visualisation of the heart’s electrical activity. Now we have even more advancements in ECG like the Holter patches and the Apple watches. Still, interpreting a 12-lead ECG is an art taught to us by experts who have themselves delved into the sea of ECGs.
