ecg generation

HI FRIENDS,

Can any body give the matlab code for generation of ecg signal from sine wave.

Detection of ecg also.

Thank you

generate ecg waveform in matlab

In this example, we shall simulate the shapes of the electrocardiogram for both
The following commands create an electrocardiogram
signal heart might produce assuming a 4000 Hz sampling rate.
The heart rate for this signal is approximately 89 beats per minute, and the
peak voltage of the signal is 3.5 millivolts.
x1 = 3.5*ecg(2700).';
y1 = sgolayfilt(kron(ones(1,13),x1),0,21);
n = 1:30000;
del = round(2700*rand(1));
mhb = y1(n + del);
t = 0.00025:0.00025:7.5;
plot(t,mhb);

good day sir,
in the code the function ecg is not defined.can you please mention what to write in place of ecg so that i can run the code in matlab.
Presently it is showing undefined ecg .

thank you

Hello sir

I to want to generate the ecg in matlab.The code here is not running as ecg(2700)
is not defined.
Kindly give me the code
thank you

the code mentioned here is not working properly to generate the ecg signal.
Kindly tell me what to do.
Matlab shows an error when i run it as ecg(2700) is not defined
