A valuable talent for medical practitioners, especially those in cardiology, emergency medicine, and other healthcare disciplines, is learning to read an ECG. The electrical activity of the heart is represented graphically by an ECG, which aids in the diagnosis of a number of heart illnesses and anomalies. Here is a simple explanation of how to read an ECG:
Recognise the fundamentals:
The waves and intervals in an ECG stand in for various stages of the heart cycle.
Electrical voltage is represented by the vertical axis, while time is represented by the horizontal axis.
Recognise the waves:
Atrial depolarization (contraction) is represented by the P wave.
Heart contraction (ventricular depolarization) is represented by the QRS complex.
ventricular repolarization (relaxation) is shown by the T wave.
