Picking up ECG signals from body is a challenge for any project. During our experiments, we found out these passive electrodes are the most reliable way to connect to body for picking up of ECG signals for further processing by electronics. Interface to these electrode is via commonly available 4mm banana plugs (Same used in multimeter leads). You can even use readily available multimeter leads as interfacing cables, thus simplifying your stage till picking up signals so you can concentrate on making electronics work.

Since, these are procured from professional medical supply so are little bit high on cost but should be reliable enough to get result in your projects. 

After pickup from electrodes you can process the signal in Opamps like AD620 or INA333. You can refer to these two IC's datasheet and their application notes for ECG processing idea.

Note for buyer: These are set of four passive electrodes, It does not contain any electronics or opamps.
