A heart monitor is a type of portable electrocardiogram (ECG). It continuously records the heart's electrical activity for over 24 hours or longer while you are away from the doctor's office. One of the easiest and quickest measures used to assess the heart is a normal or "resting" ECG.

Portable EKG or ECG (electrocardiography) has been recognized as an important innovation in the medical industry which can transform the status quo of medical care. This portable device can significantly help in the early detection of cardiovascular diseases, such as, arrhythmias, cardiomyopathy, and heart failure to name a few.

In this modern time, scientists and researchers have taken an interest in developing health trackers and portable health monitor devices wherein they are now starting to change how the medical industry works. They are now trying to tackle how to utilize sweat on assessing the physiological factors of the human body. This might also help determine how well medications, or diet and nutrition, function in certain people in order to manage health issues.

One of severe symptoms of COVID-19 is extremely low blood oxygen level, or hypoxia, which causes blood clotting. In most cases of lung diseases, like pneumonia, low oxygen saturation in blood results to fluid-filled or stiff lungs, increased level of carbon dioxide, and shortness of breath. However, many COVID-19 patients with hypoxia didn't actually show any of these signs in the early stage of infection. Doctors reported that these patients live their lives normally and generally describe themselves as comfortable.

On the onset of COVID-19 pandemic, many of us were forced to stay in our houses. Even so, we still have to go out every now and then to either buy food, medicine, or just simply go to work. This made a lot of us to be fearful that we may have been in contact with someone who has the virus while we're outside and that we may have also contracted the disease.
