ABSTRACT
This paper presents the development of CardIoT - a portable electrocardiograph
for performing ECG exams with up to 12 leads based
on Internet-of-things. CardIoT has a touch-based graphical interface
for configuration and real-time visualization of ECG signals.
This work stands out from related works concerning the connectivity
with any FHIR server, i.e., no dedicated servers are required to
support CardIoT because CardIoT’s records are compatible with the
FHIR standard to enable interoperability. In case of loss of internet
connection, the device has a memory card slot to back up exam data.
An experiment simulating a real ECG exam showed the functionality
of an ECG signal acquisition board and embedded firmware
developed for the Microcontroller in the development platform. A
second experiment proves interoperability as the exclusive feature
of this work by showing CardIoT can communicate and send ECG
samples to a third-party FHIR server.
