When I had a heart attack recently, it occurred to me that the devices on the market for heart monitoring were woefully simplistic and in some cases inaccurate. And the fact that I couldn't go to cardiac rehab due to Covid-19 made it all the worse. I decided that based upon my experience there must be other people out there who wanted a monitored, multi-lead ECG (watches only have one lead) that could also transfer data to a cloud, both for data-capture, real-time monitoring, and/or predictive analytics. Something in between a watch and an ICU monitor.

PICSI is a small (50x65mm) wearable that provides the ability to stream near-real-time waveforms to a mobile device, view it on the 2.8" touch display, in addition to the ability to visualize augmented data on augmented reality (AR) glasses.

PICSI is unique in that it can capture a complete diagnostic 12 Lead ECG (watches and other "2 finger" devices only capture a single lead of ECG - not considered "diagnostic quality".

PICSI can also capture or receive via BT: SPO2, NIBP, temperature. It has a 9 axis IMU for patient fall/out of bed precautions.

PICSI Cloud network can receive these data, and process in an AI predictive algorithm to do predictive analytics for 12 lead and ST-segment measurement - the only true harbinger of a heart attack. The cloud provides a number of services from electronic medical record (EMR) integration to home 12 lead capture for youth athletes and older concerned citizens. It is planned to be reimbursable for mobile cardiac outreach telemetry (MCOT), 24-hour ambulatory monitoring (Holter), and Telehealth applications.

The companion app lets you store long-term parameter data (including waveforms) to a SQL database that is synchronized with the cloud.

The 2.8" sunlight viewable display has a capacitive touchscreen. The waveforms can be streamed to any other BT compatible tablet. You've heard of the $100 laptop? This becomes the $999 ICU monitor.

The device make good use of a number of Analog Devices technologies for ECG, ADC, and inductive power. The system charges on a stand and runs for 12 hours on a full charge. The device uses a very thin 12 lead cable, a custom multi-lead BT chest electrode and even had 4 nickel electrodes on the back in order to be simply pressed against the chest for spot analysis.

    A few years ago, I picked up the phrase "Shibui" (https://en.wikipedia.org/wiki/Shibui) which is a Japanese term meaning. to quote Wiki "Shibui objects appear to be simple overall but they include subtle details, such as textures, that balance simplicity with complexity." I have been an engineer, clinician, and patient and so I like to think from a patient advocacy POV using the latest System-on-Module technology to do a whole lot with very little. I have also been an amateur radio operator for over 40 years and feel perfectly at home, in either analog or digital, RF or AF and use that knowledge of antennas and duplexers in order to maximize antenna coverage for PiCSI.
