According to medical staffer Felicity Lee, "the electrocardiogram showed complete heart block".
A second ECG, which the man performed and quickly emailed to the doctors, showed even more signs of a heart attack.
To save his own life, he set up an intravenous line for drugs, including clot-busters and painkillers.
He also "attached his own defibrillator pads and prepared adrenaline", and administered himself drugs needed to correct his irregular heart rhythms and clear the blockage in his heart.
The report says the procedures bought him the necessary time until emergency help arrived.
He was then flown to a cardiology centre in Perth, where he received a stent before being discharged 48 hours later.
Although the nurse did everything right and probably saved his own life, the report warns that "a person's self-management of a [heart attack] cannot be considered medically appropriate if any other option is available".
