CardioDial is a single-lead battery-powered electrocardiograph device equipped with IoT connectivity. The integrated radio makes it always ready to start and transmit a recording at the onset of the symptom, thus allowing to obtain ahigh-quality ECG trace with significative information content because it is strictly related to the symptom. Subsequently, once the tracing is received, the server will output an interactive PDF and send it via e-mail to the clinician and possibly also to the patient.
