<p>Currently, remote monitoring systems have evolvedto respond
to the peculiar needs in the healthcare industry, suchas Cardiovascular
diseases, which is an essential foundation in themodern concept of the smart
city. We propose a system to monitorpatient current health conditions as a
healthcare system basedon the widely spread available low-cost technologies,
namely,GSM and Arduino platform. Statistics show that hypertensiveheart disease
and blood pressure are risk factors for the highdeath rate. To decrease it,
preventive measures should be appliedproviding a health monitoring system to
save the patient life atan acceptable time. The objective of this paper is to
developa prototype of a low-cost system, that is capable of performingremote
monitoring of a patient’s heart rate and body temperaturein real-time and
stores the data on the memory card using low-cost hardware such as Arduino, and
also, using the servicesprovided by the GSM network, to enable communication
witha health specialists cell phone upon request or if there areanomalies in
the values measured by the sensors. The studyfocuses on heartbeat rate using
the Difference Operation Method(DOM), described by Yeh & Wang, and body
temperature, thus,in case of emergency, a short call is done, and then an SMS
issent to the health specialist’s mobile containing measured values.Using this
algorithm and after some tests using data from theMIT BIH Database
distribution, we manage to find the bestsample frequency and eliminate the
distortion of the signal.</p>
