![]() They can tell from the “lub-dub” heart sounds if its rhythm is consistent and within normal parameters. One of the first things doctors do during a visit is listen to your heart. A life-saving operation can never succeed if the patient has not been diagnosed correctly. Getting a diagnosis has become a bigger factor than the operation itself. While any surgery has a potential for unexpected complications, the success rate continues to climb, as what were once unthinkable procedures are now all but routine. ![]() While this may or may not be a response to COVID-19, I believe it will quickly evolve into a powerful tool, if medical test equipment keeps up with this demand.Īny insight we can gain into how our bodies are functioning can be a step in the right direction. We are now beginning to see that evolve further into virtual visits. It didn’t take long for doctors to realize they could see more patients if the patients came to the doctor’s office. When I was a youngster, a doctor visited our home to diagnose illness and prescribe medicine. In this month’s project, I make a small (3-electrode) heart rate monitor, using the Sparkfun AD8232 Heart Monitor module, which is based on the Analog Devices AD8232-a dedicated electrocardiogram front end. Non-laboratory-grade test equipment for personal use is becoming popular, and I see a future in which we all have some kind of equipment in our homes that can monitor body parameters and transmit them to a physician during a virtual house call. One area I’ve not toyed with is heart monitoring. Whodathunk! I’ve done projects in the past on recording brain waves, and know that the body has a lot of electrical activity going on inside, besides brain activity. I was disappointed to find that once I had worked up a sweat, my watch was not so effective in taking my vitals. I don’t belong to a gym, and winter-along with the festive seasonal food-take a toll on my body every year. This season, as in the past, I find my weight rises a good (bad) 20 pounds from my normal summer weight. ![]() ![]() I have to admit that right now I am on hiatus, while watching people out on the lake ice fishing. Since I enjoy running outside when the weather is comfortable, I thought it would be fun to monitor those parameters during my jaunts around Crystal Lake, where I live year round. I don’t have an Apple watch, but the one I wear does monitor heart rate and oxygen sensing. ![]()
