1. Enlargement of right ventricular myocardial mass can result in right axis deviation . 2. The congenital condition of dextrocardia results in right axis deviation . 3. The ventricular beats typically have a right axis deviation . 4. Tachycardias originating in the anterior left fascicle would lead to right axis deviation . 5. Changes in the conduction pathways of the heart can result in right axis deviation . 6. If the QRS complex in lead II is also negative, this confirms a left axis deviation . 7. An ECG with right ventricular hypertrophy may or may not show a right axis deviation on the graph. 8. When the origin of the ectopic heartbeat is in the anterior fascicule then there is right axis deviation . 9. The most commonly seen signs in the ECG are sinus tachycardia, right axis deviation , and right bundle branch block. 10. Individuals with a sinus venosus ASD exhibit a left axis deviation of the P wave ( not the QRS complex ).
