E. Atrial flutter – Explanation
If you look at V1 alone, you would see the characteristic “flutter waves” which are a “sawtooth” shape.
The flutter waves replace the P waves. In general, this is managed in the same way as an atrial
fibrillation.
ATRIAL FLUTTER VS ATRIAL FIBRILLATION
| Atrial flutter | Atrial fibrillation | |
| Atrial activity | Rate: 220-350 bpm | Rate: > 350 bpm |
| Visible flutter (F) waves | Fine fibrillatory (f) waves | |
| Ventricular activity | Rate: Regular Constant R-R interval |
Rate: Variable No relation to atrial rate Variable R-R interval |
| Baseline | Sawtooth | Ragged |
