Fetal atrial flutter

Fetal atrial flutter is the second most common fetal tachyarrhythmia and can account for up to 30% of such cases 1-2

As with other tachyarrthymias it is often detected in the 3rd trimester.

It has a typical atrial rate of 300-600 beats per minute (bpm) and often has a variable ventricular rate due to the frequent presence of an AV conduction block (often 2:1 atrioventricular conduction 2):

  • mean atrial rate: 440-520 bpm 2,8
  • mean ventricular rate: 200-250 bpm 2,8
