When electrical activity (or depolarisation) travels towards a lead, the deflection is net positive. When the activity travels away from the lead the deflection is net negative. If it is at 90 degrees then the complex is ‘isoelectric’ i.e. the R and S wave are the same size.

WebECG paper is a grid where time is measured along the horizontal axis. Each small square is 1 mm in length and represents 0.04 seconds. Each larger square is 5 mm in length and represents 0.2 seconds. Voltage is measured along the vertical axis. 10 mm is equal to 1mV in voltage. WebThis means that one small box’s width is 0.04 seconds. Five small boxes, the distance between thicker lines on the ECG, are 0.2 seconds, and the distance between 5 thicker lines is 1 second.
