Problem in powering AD8232 Single lead heart rate monitor board

Hello to everybody, 

I have some problems in powering the two AD8232 boards I have recently bought from Sparkfun (SparkFun Single Lead Heart Rate Monitor - AD8232 ...): when I power it, the red led continue to randomly turns on and off, and I have to spend a lot of time in moving the board before it reamins stable; the same thinghs happen when I  plug the electrode pad jacket into the appropriate socket.
When, finally, the led is stable on the red, I notice that it fades and continue to blink when I am measuring my heart rate.
Initially I thought it was due to some false contacts on the breadboards, so I tried to solder wires on the connector (GND, 3.3V, OUTPUT, LO-, LO+) but anything changed, so I thought that or I was so unlucky I have bought two defective boards, or there are something wrong.... but was ?
Could someone be so kind to help me ?
