Hi guys, I'm looking to make a simple ECG based on Arduino, but I'm not really sure, do I need some sort of an amplifier chip between arduino and the leads? or can I just connect the leads to the arduino's inout pint? Thanks.

Anduino ECG - do I need an amplifier?

I want to plot the whole ECG and transfer it via bluetooth to a smartphone, that would analyze it and draw the waveform on screen.
