Arduino ECG EKG Heart rate monitor circuit prototype

[newnes90]

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

[petertcool]

post the source code pls ^^

[Shuffle3956]

What's your name again?

[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!

[MrLolztome1]

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.

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

Hi,

I have a question for you, when I ground my body, i cannot get any signal displayed on the oscillscope? do you know why? When I just use two electrodes, I can observe the 50Hz power line noise.

thanks

Cool.. nice project.! I like it.

I also use ecg biofeedback + Arduino for my project.

your work is really helpful for me. thanks.!!

Hello

what kind of sensor did you use?Thanks!

[unmanaged]

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.

[bigdinotech]

@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.

Hi,

I am doing a similar project. Please let me know which software you used to calculate heart rate? Thank you.

[bigdinotech]

@abhyhhh I created my own program using the Arduino IDE. The language itself is based on c++, so its really easy. In terms of calculating the HR, I simply detected two R peaks and calculated the time between the peaks. I then used this info to calculate the effective HR over a minute.

great job!

[salil2192]

what was the amplitude of the ECG signal that you fed in to the ADC of arduino?

[bigdinotech]

@salil2192 the peak of the R wave was at around 380 mV

[MrHorsetail]

That's some real good work. Are your electrodes just wires taped to your body, or are they some kind of electrodes designed for heart monitors? If they are plain wires, does the micro voltage come from the heart beats or what?

[bigdinotech]

@MrHorsetail They are plain wires soldered into some pennies. Which is then taped to my body. Its not very reliable since the tape sometimes gets lose and the pennies lose conduction with my body. I plan on getting some real ECG patches soon but that will be for th finished project. And yes, the signal comes from the beating of my heart. This circuit works exactly the same as the ECG machines found in hospitals only 1000x cheaper.
