The Herald Sun spoke to one of those patients, 39-year-old Colin Fiedler, who was clinically dead for 40 minutes after suffering a heart attack last June.
"I'm so grateful, more than I could ever say," he said.
Doctors at Melbourne's The Alfred hospital used a mechanical CPR machine called the AutoPulse, to perform continuous chest compressions on patients like Fiedler. They also used a heart-lung machine to transmit blood and oxygen through his body.
Of the seven patients who have been treated using the new techniques, three were brought back to life without injury after being clinically dead for 40 to 60 minutes. The Alfred Hospital's Stephen Bernard said he hoped to expand the treatment throughout the city.
