@anjimlynch Sorry, I have AF on-the-brain. 🙂 But really, alla same, alla same. Neither arrhythmia is dangerous per se, not for weeks and months, but it depends on the rate. If your rate exceeds 100 BPM for 24 hours, then you would be advised to seek help at an ER. In your case, you're only going to go about 24 hours, and believe me, your EP will be most grateful if your heart obliges by being cranky off the drugs.
