Dear Judy, thank you for your question. Right axis deviation refers to a change in the orientation of the electrical axis of the ECG that clinically is rarely clinically significant. Normally the electrical axis of the ECG is between - 40 and 120 degrees. The axis has to be > 120 degrees in right axis deviation. The echo and Holter monitor should be able to determine the cause of your murmur and palpitations.
