ECG: The axis refers to the frontal plane direction of the net forces represented in the p wave, the QRS and the T. Each of these has its own axis and normal range for each. Zero degrees is toward the left, -90 is toward the head and +90 toward the feet. There care various possibilities for abnormal axis.
