The AD8232 single-lead heart rate monitor front end, shown in Figure 1, was developed for this kind of low-power wearable application. It includes an instrumentation amplifier with a gain of 100 V/V and a high-pass filter to block the offset voltage generated by the half-cell potential ...
In particular, the COVID-19 pandemic has caused a surge in demand for devices capable of monitoring multiple vital signs, including temperature, SpO2, and heart rate both in hospitals and at homes. The need for small and convenient health tracking devices, preferably smart wearables, ha...

a rate of about 20 per minute. This may occur if the cells of the upper chamber fail to generate an electrical impulse or if the electrical signals to the ventricle are blocked. However, these lower rates may be associated with the inability of the heart to pump blood to the body to ...
The heart is an electric pump with the purpose of sending oxygen-rich blood through the arteries of the body to every organ and cell to allow them to function. The heart is a muscle and needs a constant supply of oxygen. There are three main arteries to the heart: the left anterior des...
