Ancient and modern ways of hearing the heart beat are demonstrated.
Story ancient and modern ways of hearing the heart. Part of the STREAMLANED issue.
Mock up of a female Victorian patient consulting her (male) doctor. The costumed Doctor removes his simple stethoscope from his hat and listens to the patient's heartbeat.
CUs of various old fashioned medical stethoscopes.
Shots of 1930's woman patient being treated by her doctor - he uses the kind of instrument more recognisable today.
Shots at Kings College Hospital, London - two women in bathing costumes sit on a chaise lounge. A doctor comes in and attached a device to one woman's chest with a strap - it is part of a medical invention called a phono stethograph.
Shots of a technician preparing a wax disk recorder - this records the heartbeats picked up by the device on the woman's chest. We look back at the patients as they sit with the doctor.
The two women now get up and exercise so that the machine can record the heartbeat when exerted. The doctor refits the device and takes another measurement.
The wax disk is now played back and we can hear the heart beat. We also see an oscilloscope reading displaying the beat. The two women look at the oscilloscope.
