Arduino ECG EKG Heart rate monitor circuit prototype

Prototype of the first part of my latest project which is an Arduino ECG heart rate monitor.
This circuit uses electrodes connected to the human body, amplifies the signal using an instrumentation amplifier, filters the signal then sends it to the Arduino. The arduino then calculates the effective heart rate.

This is just a prototype of small part of my project.
Future goals include:
-Sending the data via wireless to single receiver, allowing more than one device to monitor then transmit. Most likely, I will be using the Xbee to do this.
-Receiver would be connected to a PC and communicate using USB or Serial.
-Create a program, probably based on processing, that would display the heart rate and log it into a database according to each patient. Program would also issue warnings if the heart rate is dangerously high or low for a specific person.

Pls feel free to leave comments or ask questions.
Thanks,

hey dude can u giv me the circuit diagram and coding to me???

[bigdinotech]

@MrLolztome1 The circuit diagram is based on the circuit from the example in the datasheet for the INA2122 instrumntation amplifiers. I did not make an actual schematic since this was just a prototype. I can give you the code if I can find where I saved it.

would you be willing to kit this up? What IA did you use..?

[bigdinotech]

@unmanaged Sorry no plans on making a kit. i did this project mainly for educational purposes. The Instrumentation Amps I used are from TI they are INA2122.

Hi,

I am using Arduino UNO to get heart rate. I used the given example code in ArduinoInOutSerial. Did you write the code in this program? Please let me know how or where you created your own program using Arduino IDE. I will greatly appreciate your help. Thank you.

@abhyhhh I used the analogRead() function of the arduino. The input comes from the ECG circuit that I built which is connected to one of the five analog ports of the Arduino which has an ADC. From there I simply read the data using analogRead() and simply calculate the time diff between the two peaks. For this i used the millis() function.

What's your name again?

[newnes90]

Hi.can you please show the coding of Arduino?how Arduino calculate heart beat?

[petertcool]

post the source code pls  ^^

[krazyk551]

@bigdinotech May I also view the arduino and processing code?

[fairuz56]

Hai...,i do similar like this project..can u give the code for me??i already get the signal..now in process to calc heart rate...plz!!!

[wear2whale]

Amazing.

[ionutcelgroaznic]

There is a typo:ina 2122 you mean 2126?

[MrLolztome1]

hey dude can u giv me the circuit diagram and coding to me??? also is it possible to make a 12 lead version?

[MrLolztome1]

thanks :) plz do send me the coding!
