 In an effort to reduce the cost of insurance, the men agreed to form the volunteer Miami Fire-Rescue Department.In June 1969, the department became the first in the United States to successfully revive a patient in the field through defibrillation.By using radio transmission of an EKG, as well as radio contact with doctors at Jackson Memorial Hospital and the University of Miami School of Medicine, the firefighters were able to administer a shock to the patient who was revived from a lifeless state.
