I have just recently had an ECG, with the following diagnosis: Left access deviation, poor R wave progression, Left anterior hemi block and masking inferior infart. Poor R wave progression possible clock wise rotation, but can t exclude infarct. My GP didn t explain anything to me other than he will be sending me for a stress test. I don t know the seriousness of this condition, and would like to as the Doctor recieving the referral is away sick and it s unknown of his return.
