I need free online data about heart murmurs to study these:

heart murmur frequency , S2 heart sound frequency and its split, murmur timing, and duration, murmur intensity, S3 sound presence and intensity, S1 presence and intensity, presence of ejection sounds and arrhythmias

I will cite your source then if I can use your data freely.

I would really have the same data as used in this paper:

Heart energy signature spectrogram for cardiovascular diagnosis Vladimir Kudriavtsev, Vladimir Polyshchuk and Douglas L Roy

Does anyone have simple data for my task?

I remember that some CD of some book has some standardised nicely organised sounds that you can use freely.

Where does ECG come into this? It seems like a question about auscultation. What sort of data are you actually looking for? –  Rory M Oct 16 '13 at 22:44
Normalised and well measured. This type of data: dl.dropboxusercontent.com/u/62073194/bmt-2012-4075.pdf They do not share their data publicly. I have asked for the data, but they have ignored my request and do not want to share it. –  Masi Oct 17 '13 at 3:44
