This is a somewhat overcomplicated concept and is frequently irrelevant to clinical practice. There are only three main areas where identifying cardiac axis has clinical relevance. The first is when trying to decide whether there may be ventricular tachycardia present on the ECG. An abnormal cardiac axis may help one to conclude that this is VT rather an SVT. Secondly, when an accessory pathway is present, it helps to localise the position of the pathway within the heart. This fact is useful largely to electrophysiologists rather than the rest of the profession. Finally, when the patient has RBBB, if a left axis or a right axis deviation is present, this represents abnormality of both bundle branches and may precede complete heart block or asystole in the future.
An easy way of establishing axis is to look at lead I, II and III.

Dr Sharp qualified from Edinburgh Medical School in 1998. He was appointed as a Consultant Cardiologist at the Royal Devon and Exeter Hospital in 2011 and Honorary Associate Professor by the University of Exeter in 2018 before moving to the University Hospital of Wales in the summer of 2019. He conducted his early training at the Royal Infirmary of Edinburgh, before moving to London for his senior clinical training. He completed the prestigious Milan-Imperial Interventional Cardiology Fellowship programme, having spent a year in San Raffaele and Columbus Hospitals, Milan, Italy, under the tutelage of Professor Antonio Colombo. He also spent three years training in interventional cardiology at St Mary’s Hospital and The Hammersmith Hospital (Imperial College Hospitals) in London. Dr Sharp was awarded an MD postgraduate research degree from the University of Edinburgh for his work on the hypertensive heart and led a large research programme at the Royal Devon and Exeter Hospital, which he is now establishing in Wales. He has been Principal Investigator in more than 30 ethically-approved research trials since 2012 and has published extensively. He has an international reputation for leading the development of device-based treatments for hypertension (in particular that of renal denervation) and pulmonary embolism, as well as the advancement of intracoronary imaging and physiology.
