The most common causes of left axis deviation are left anterior fascicular block and inferior Q waves secondary to acute myocardial infarction. The symptoms of left axis deviation are determined by the underlying reason. It may indicate the presence of various conditions, such as left ventricular hypertrophy, left anterior fascicular block, inferior wall myocardial infarction, emphysema, and mechanical shift due to elevated diaphragm because of obesity. Secondly, there is a need to interpret the spectrum of QRS patterns seen in patients with LVH, such as such as the increased QRS voltage, the QRS voltage within normal limits, occurrence of left axis deviation and LBBB, in electro-physiological terms; i.e. Respiratory sinus arrhythmia is effectively benign, meaning that it is not harmful. The optimal diagnostic approach in a seemingly healthy child with LAD is unclear. The abnormal left axis deviation is one of the most common abnormal ECG findings.

Electrocardiogram of left ventricle hypertrophy. Common causes of left axis deviation include an old or recent myocardial infarction, paced rhythms . Block in the posteriorfascicle causes leftposteriorfascicular block (LPFB). Being able to determine the electrical axis can give insight into underlying disease states and help steer the differential diagnosis towards or away from certain diagnoses. This is reflected by a QRS complex positive in lead I and negative in leads aVF and II.. Each clinical case scenario allows you to work through history taking, investigations, diagnosis and management. Left posterior fascicular block is much less common than LAFB. The electrical axis will be more positive than 90 (right axis deviation). Geeky Medics accepts no liability for loss of any kind incurred as a result of reliance upon the information provided in this video.
