As a medical professional with expertise in cardiology, I can explain the significance of the squares on an ECG (electrocardiogram) paper. ECG paper is designed to standardize the representation of the heart's electrical activity. Each small square on the ECG paper represents 0.04 seconds (40 milliseconds), and there are 5 small squares in a large square, making each large square equal to 0.20 seconds. Vertically, each small square represents 0.1 millivolts (mV), and each large square (5 small squares) represents 0.5 mV. This grid system allows healthcare providers to accurately measure and interpret the various waves and intervals of the heart's electrical activity.
