i need help from any1 regarding wat kind of circuit can i use... i have written the program in matlab so if anyone could help me with this... please do its urgent

 

One suggestion we made with a similar request is to record ECG's into audio files so they can be played back.

 

do u ve circuit diagram of that... if please.... mail to my id i would be very glad <snip>

What is the nature of the output of your ECG equipment? If it is analog, it can be recorded through a computer's sound card.

 

i am still building it i am confused with what circuit shall i design whether to build with dsp processor or by wave shaping circuit.. so if u could help me i would be very happy

Using a sound card to record ECG is not optimal. As the sound cards is AC coupled. And hence has a cut off around 15Hz. This will remove some of the lower frequency Content of a ECG signal. But if you only are interesting in doing heart-rate calculations. A sound card will work fine.

 

This is a ECG complex. As a start. You can repeat a ECG complex every time. And vary the interval between them. This will be a good approximation for a healthy person.

 

i get that.... the main problem is that how to design the circuit to get that output... wat are the components??????

 

Many solutions will be able to solve this problem. It is not one solution. Google is your friend. It is better that you do the research. Then come to us for help and comments

 

Are you aware that these are commercially made and certified?

The components are a Mac running GarageBand. Draw the trace, repeat it forever as "music". Done.

 

Sounds like you are asking for an electronic ECG simulator circuit that you can feed to a MATLAB program for analysis. Is that the case?
