Vertical axis

vertical axis means that the overall direction of ventricular depolarisation is straight downwards (head to toe). This direction is also known as +90 degrees. If the axis is vertical, Lead I will be isoelectric and aVF positive. A vertical axis is classically caused by chronic lung disease, but there are other causes.
