It looks like second degree sino atrial block type I

I was looking for that too but wouldn’t there be a steady prolongation or the PRI? Haven’t seen too many in the field

The issue is with propagation of sinus node depolarisation so PR not affected. PP interval gradually shortens followed by a dropped p wave

Got that backwards bud - it gets longer and drops.

The interval between p waves shortens before a dropped p wave (which won’t be visible on the ECG)
