    19 Μαΐ 2024 · To use the heart axis calculator, you have to calculate the net amplitude of the QRS (see QRS morphologies). Subtract the Q wave and the S wave amplitude from the R wave amplitude. If the result is negative, the minus sign must be used (for example, -2). QRS = 12 mm. QRS = 1 mm (R wave: 7 mm - S Wave: 6 mm).
