ECG Device

Theta Engineering designed the packaging and did the electrical re-design of a battery-operated ECG (electrocardiogram) device which interfaces via the serial port of an ordinary PC for display of heart waveforms. Analog portions of the design were modified and the digital portion was completely redesigned and updated using modern components and a Microchip PIC microcontroller, while adhering to FDA performance and safety standards required for a medical device such as this. Theta Engineering also wrote the firmware used in the PIC microcontroller.
