GY-MAX30100 issue

[Esp8266-hax0r]

I connected the purple oximeter to the Arduino Uno with the following connections:

VIN - 5V
GND - GND
SCL - SCL
SDA - SDA
INT - D2

But it shows me this:

13:16:02.851 -> Pulse oxymeter test!
13:16:02.851 -> BEAT
13:16:02.851 -> BPM: 8616.35 | SaO2: 92.01%
13:16:03.055 -> BEAT
13:16:03.055 -> BPM: 4313.73 | SaO2: 92.66%
13:16:03.089 -> BEAT
13:16:03.089 -> BPM: 1209.15 | SaO2: 92.74%

I used the example sketch from github.
How can I fix this?
