A nurse in an isolated town on Australia's far west coast managed to diagnose and treat himself after a heart attack.
The case was published this week in the New England Journal of Medicine.
The 44-year-old nurse was stationed at a nursing post in Coral Bay, about 1000km from the nearest major city, Perth, when he started suffering chest pains.
He pushed past the pain to give himself an electrocardiogram (ECG) and emailed the results to an ER physician through Australia's Emergency Telehealth Service.
According to medical staffer Felicity Lee, "the electrocardiogram showed complete heart block".
