Hi,

I am looking for circuit diagram of ECG Simulator (preferebly 12 Lead). If any one can help me with it. The ECG simulator is a device which generates PQR rythem just like your heart generates and with its help you can check and test a normal vital sign monitor.
Thanks in advance.

 

I have have same with your project.It's difficult,nobody publish on the web
uhhhh....

Hi there,
One of my firiends have informed me that he can help me with it, infact he has the entire project in his hand. If I get it I will publish it on web.

Ok thanks, guy. I waiting for the circuit. Can u send by address mail:

tofikmulianto@yahoo.com.sg

It's very important to me

Regards

 

alslamo alikom
plz if u got the circuit could u pass it to me ( mghtt84@yahoo.com)
thanks

 

Im also interested..please pass it over to me too meindg@yahoo.com

 

Oh my god Too many PATIENTS on the way!

Emulating each of the leads in an ECG/EKG recording, assuming one wants a change in one lead to be appropriately represented in each of the others, would require a understanding of cardiology and the mathematical models for heart conduction. Nevertheless, such a program would be very useful for teaching, and I was surprised the previous postings seemed to find such a dearth of information on the subject.

So, I did a quick search on "ekg emulation" and got numerous hits, including ones that gave both electrical and audio emulation. Here is one that looks interesting and is may be right on point:

This thread is REALLY old and filled with a bunch of slackers looking for a hand-out, I don't know why there are recent messages.

 

thanks mr. jpanhalt , but i'm still looking for a designed circuit ... if u or anyone knows the circuit could u pass it over and i'll be really grateful .....

 

I am not quite sure what you exactly you want. For example, it would seem really quite difficult to design, in hardware only, an electronic circuit that would mimic the EKG wave pattern for each lead and would allow changes as needed for instructional purposes.

My guess is that anything that could do that would be primarily software driven, probably on a PC, and the hardware would be relatively simple. It would probably include multiple outputs and D/A converters for each channel, which also assumes that you want an analog recording.

Why wouldn't a display on the PC monitor suffice, which brings this comment full circle to asking you to be more specific in what you are trying to do. JOhn

 

the purpose of this simulator is to Exam an ECG device or check the cables because i faced that kind of problem and i had to test the device on me and this is not practical ..... so i need a hardware design which i believe its already exist.

 

Why not record several channels and play them back on an endless loop.

 

First and foremost, if you are doing real-life testing, you should obtain a device designed, thoroughly tested, and approved for that purpose. I would not want to trust my life or anyone elses to something a hobbyist devised from information on this site.

You rarely see a patient who walks in and has a flat line on EKG (some patients die waiting). Thus, there is what can be called an internal standard. A qualified technologist should be able to tell a mechanical or electrical problem from a physiological problem. John
