Problems with readings with ad8323(ECG device)

Hey. guys. i have a problem.

I connected the ad8323 board to an arduino uno which I connected to my laptop.

The voltage at 3,3 v is on the 3,3 v supply pins (that is apparently not the problem) , all pins seem to be normal.

The code I used (seems to be the standard one that comes with all manuals):

void setup() {

// initialise the serial communication:

Serial.begin(9600);

pinMode(11, INPUT); // Setup for leads off detection LO +

pinMode(10, INPUT); // Setup for leads off detection LO -

}

void loop() {

if((digitalRead(10) == 1)||(digitalRead(11) == 1)){

Serial.println(‘!’);

}

else{

// send the value of analog input 0:

Serial.println(analogRead(A0));

}

//Wait for a bit to keep serial data from saturating

delay(1);
}

The problem is that I get some kind of sinusoid instead of ECG graph (and if some contact is badly seated, there will be 2 graphs, otherwise, the one I showed above). This is definitely not my heart rhythm, because I am not dead(sort of). I would be grateful if you could help me, please.

When the contacts are poorly applied to the body(2)

I also noticed that the LED on the ad8323 inside the heart pattern lights up alternately, maybe this has something to do with it.
