A passenger onboard a recent bmi flight from Chicago to Manchester, England, became the first commercial airline passenger to have an electrocardiogram (ECG) in flight with data from the procedure transmitted via satellite to physicians on the ground.

Stephen Clarke was traveling on bmi when he experienced chest pains. His ECG images were sent via satellite to physicians on the ground in Phoenix. They were able to make an immediate diagnosis of a heart attack. Under their supervision, bmi flight attendants administered emergency treatment from the doctor’s kit onboard. After a short stay at Wythenshawe Hospital in the United Kingdom, Clarke was discharged.
