This is a heart reading being transmitted from the stethoscope to an IP telephone. The reading can be recorded and stored for future reference.
Alternatively, doctors can analyse the reading using software. The top graph shows the spectroscopic reading, with the colours representing the energy within the frequencies of the heartbeat.
On the top right-hand side of the screen — the anatomical picture of the heart — doctors can record which part of the heart they were listening to when recording the reading.
Patients can take their own blood pressure readings which are fed via Bluetooth to a mobile phone and sent to a database, which the patient and their medical practitioner can access.
