Medical query re dvla

any help or advice needed as i am going round in circles.i recently had an icd defibrillator fitted after suffering a sudden cardiac arrest,i was told by consultant to notify the dvla,anyway i voluntarily handed my licence in as was led to believe i was automatically excluded from driving lorries forever.
i am waiting for a confirmation letter from the dvla to say they are in receipt,which they confirmed in a phone call 2 weeks ago still waiting ,once i get the letter i can get a bus pass ha im only 49 but any help will do as i am only getting £78.00 a week ssp,not entitled to any benefits as missus works.anyone able to give me advice it says on my icd card good(LVEF>50%)is that enough to warrant my exclusion from driving lorries i feel fine blood pressure perfect,
