I have a data file of pressure measurements of an animal heart in the form of Pressure vs Time. However, the sensor picked up some mains line noise (60 Hz). How do I low-pass filter it?

The data file is in the form of:
time1 pressure1
time2 pressure2
time3 pressure3

The interval is not the same. However, I can interpolate to fix it.
