Usually MIT-BIH ECG database (PhysioNet) is used as a benchmark to compare your results to others in publications since many researchers use it.

I have used the MIT-BIH database only, but there are some other databases:

1) AHA: https://www.ecri.org/Products/Pages/AHA_ECG_DVD.aspx

2) CORD: http://escholarship.org/uc/item/3mb7n6ss#page-1 (i couldn't find the website).

Please, if you found other databases, share them with us.

I have just remembered.!!!

I have read the following paper long time ago and at the end of the paper there is a section called "Benchmark Databases" which mentions all of the online available databases:

Hello. In my research group we are working in the creation of a new ECG on-line database. We already have a version available with some signals to download. Check it out. What do you think?

Dear Carlos Alberto,

in the past decades I have personally used PhysioNet and my students too, and we were all very satisfied.

hi,

i need 15 ECG database of Epilepsiae .

can any person help me?

tnx

I must disagree sorry, but Physionet is not always a reliable database according to my short experience. For all I know, take a random excerpt of AFdb or MIT-BIH arrhythmia/200 e.g., have it analyzed by a practitioner and you will find a.s. that annotations are poor or wrong or missing and most cases are statistically unbalanced with too few patients. 

So cool question and I am also interested in knowing about the alternatives including private.

Dear Mohammad Soltani

Have you found any ECG database of Epilepsy patients? If yes, kindly share with me
