The above rhythm is Sinus Tachycardia.
Of note, had the rhythm been over 150 bpm,
the P waves would have been harder to see,
merging with the preceding T wave, and
other rhythms would need to be considered,
such as SVT or Atrial flutter with 2:1 block.
The first four items on the above differential
are unlikely to cause a Sinus Tachycardia
above 150 bpm.
