Physiological Computer System Interface

When my brother passed away a few years ago from a second heart attack I lamented the fact that there wasn’t a consumer EKG device on the market capable of detecting a myocardial infarction. All of the “consumer-grade” EKG devices were simple single-lead ECG devices that at best could provide simplistic atrial fibrillation prognostication.

In addition, there were new predictive algorithms on the market that could provide clinical analytics on a wearable device. I wanted to make a device platform that would be open to global innovation with a diagnostic-quality feature set that would avail itself to many situations requiring a wearable device with the power of an ICU monitor.

Fast-forward to two months ago, and lo and behold I find myself having chest pain, and after quickly trying to connect one of the patient monitors in my office, I decided that it was time to go to the ER to get a 12 lead EKG. It was a good thing I did as I ended up having both a cath and cardiac bypass surgery. 

This brought about a realization of yet another use-case. The local hospital’s cardiac rehab program is shut down for Covid-19, and a small wearable multi-lead ECG device that was capable of being monitored would make it where high-risk patients such as myself could have some comfort with a remote monitored cardiac device. 

Most existing ECG devices in the consumer sphere only are capable of capturing a single lead of ECG, or at best multiple placements of a single lead ECG device to capture three leads that are mathematically augmented to six. True Multi-lead ECG is required in order to visualize multiple views of the heart waveform.

Single Lead ECG has only two connections (like a watch) and produces only “Lead One” ECG. Hospital ECG Telemetry for this reason uses a five-wire connection to produce seven leads of ECG. 12 lead ECG recording requires 10 electrode attachment. See ECG Resource Page for a broader discussion on electrocardiography and the difference between single-lead ECG acquisition devices and multiple-lead acquisition devices.
