Prototype Medical Device

An electrocardiogram (ECG/EKG) is a graphic produced by an electrocardiograph, a device that records the electrical activity of a heart over time. Analysis of the various waves and vectors of the polarization and depolarization yields important diagnostic information. It is the gold standard for diagnosing cardiac arrhythmias and many other heart conditions.

Local HMI/ Network Connectivity - human machine interfaces are used for control and configuration of the measurement and a MySQL database contains all of the patient's vital information.

Main Processor - contains the software logic that operates the EKG, the acquired heart waveform analyis for anomalies and important diagnostic information and network connectivity necessary for database communication.

FPGA Hardware - hardware filter that removes noise from the acquired signal so the analysis can be performed effectively combined with common protocol used to communicate with a number of third-party peripherals.

Input/Output Hardware - directly connects to electrodes that are attached to the patient, isolation addresses safety concerns, simple serial communication can be used to talk to devices such as a thermal printer, analog output connected to a speaker, buttons and LEDs are necessary for standby and power button, indicator in addition to other features.

Sensors & Actuators - electrodes, thermal printer, speaker, LEDs/buttons, RFID
