1 янв 1958 г. - Fetal Ultrasound and Pacemaker

Описание:

Dr. Edward Hon of Yale reported using a Doppler monitor on a woman's abdomen to detect fetal heartbeat. Ultrasound's principles had been known for more than a century (a Swedish physicist, Christian Andreas Doppler, gave his name to the phenomenon in 1842), but this was its first use in prenatal care (nytimes).

Dr. Seymour Furman, a cardiologist at Montefiore Hospital in the Bronx, succeeded in extending a patient's life by more than two months using a cardiac pacemaker, a large machine to which the patient was attached by a 50-foot extension cord. By the next year, portable versions of the machine were in use (nytimes).
