An estimated 80,700,000 American adults (one in three) have one or more types of cardiovascular disease

Every minute counts. For every minute heart failure goes untreated, unrecoverable damage occurs to the heart muscle

Current heart monitoring equipment is commonly stationary, available to patients at hospitals or at their house

Patients’ lifestyle often makes it difficult for them to access heart monitoring equipment.

Health care professionals need live data on the health of their patients to help them during emergencies

Device Measure the ECG wave form and analyze Portable, wireless Detect if the user is having a heart attack or any

other heart problem. Mobile phone

Receive the alert of the device and send a message to the persons previously selected

Beyond our scope Power consumption optimization of the Analog

circuit

Software optimization. Should be easy installable within a 15 minutes by Nov 2.

Have a working prototype by Nov 21. Hand in a written system manual to the

project manager for review. It should describe all the system functionalities and legal disclaimers by Nov 24.

Tests in different scenarios. This will help to detect any situation not considered in the design process by Nov 25.

Ideally, any type of electric contact could be used

However, wearable, safe and reliable electrodes are desired for the final product

Standard medical ECG electrodes will be used Two electrodes to be placed on the patient’s

chest Third electrode will be internal to the circuit: Virtual right

leg driven

Analog Circuit Instrumentation Amplifier: AD624

Appropriate for amplifying small signals High Gain: Adjustable up to 10K High Common Mode Rejection Ratio: 80 dB @ unity

gain Low Noise: 4 nV/√Hz @1 kHz

Photo coupler: PS2506 Electrically isolates the amplifier output signal from

the rest of the device System security measure

Band Pass Filter Filters signals below 0.04 Hz to 150 Hz Average heart signal is 50Hz to 70 Hz

MSP430F149: Ultra low power 16 bit microcontroller Responsible for all needed calculation of the ECG

wave form Provides the necessary synchronization of the

system Specs:

Supports clock rates up to 8MHz 60 KB of flash ROM 2 KB of RAM 12-bit ADC 2 DAC outputs, 2 UART (serial) ports, and 48 General

Purpose IO (GPIO) pins

KCWireFree KC21Bluetooth module Class 2 module

Average power dissipation: 2.5mW Small and power efficient 10m Range Built in antenna

Interface between the monitor and the patient

Holds emergency contacts, and alerts them in case of a heart attack

Development Platform: J2ME JAVA as a development tool for Mobile devices
