Hi, has anybody an idea of how to design a circuit to simulate ECG signal?
I need to simulate this signal with a simple circuit

It depend up your target aplication.
In my case, I was used to test an AED based on QRS algorythm detection.

I done it using a PSoC uC.
The board receives a value from PC database and send to D/A module.

Note :
1 ) Due Windows is a multithread operational system. The board - timed by crystal - send an interrupt to PC software in order to guarantee data received by serial to be sampled correctly in time.
2 ) Data is cycled. It mean that samples are repeated infinitely.

The problem is that i hace to build it, I have to build a circuit that it will be able to generate a ECG signal.
Is a hardware desing

you can get a good cct from texas intruments which i'v used from their site for free and u can also find some freeware apps like Zelscope that convert ur soundcard into a Oscilloscope so u can test ur ECG out and get the output on ur PC. U just need to make some leads form some old headphones lying under ur bed or something like that...

I've been searching for a circuit of an ecg simulator for a long time
Here is a circuit that i've finally found.
If anyone have a better circuit, plz send it.

Hi
Im an EE student For our final project we decided to pursue an ECG testing Circuit, which is basically a circuit operated by a PIC 16 microchip to produce basic NSR arrythmias for ECG testing purposes ( The reason why we chose a PIC was because these kind of micro. already have a PWM controller inside) .... but we are so stuck, the reason is the lack of adequate data of the Frequency/Amplitude/and Time intervals of a common Arrhythmia waveforms and definitly the programming is an issue as well. If you have any kind or resources or schematics that would be beautiful....
Thank u ....
