Cardiovascular disease (CVD) is the main cause of death worldwide and the
type varies depending on symptom and causes. There are several procedures
to determine the type of CVD such as blood test, holter monitoring,
cardiac stress test and many more. Cardiac stress test is a procedure to exert
pressure on the heart by doing physical activities to determine heart
functionality and abnormal heart activity. It is done to gather information on
heart condition supported by evidence in the form of electrocardiogram
(ECG) signal. However, patients with heart problem will have to take turns
to run the test due to limited access to the equipment especially in
government hospital. Therefore, this paper proposed the development of
cardiac self-stress test device to provide a pre-diagnosis result based on
metabolic equivalent (MET) value. The device named “i-STress device” is a
stand-alone device integrating the use of software application and hardware.
The software was built by using MIT App Inventor 2 and the hardware built
based on Arduino 101 and Sparkfun Heart Monitor AD 8232 and the test
result saved in SD card. The device will be useful to sort out patient’s case
priority as well as providing pre-diagnosis result before conducting a real
cardiac stress test.
