2nd flutter ablation back in flutter

1st November - first ablation for flutter. EP said 80% successful

29th November - second ablation. EP said 99% successful after using 3D mapping

High heart rate started 10 days ago (90bpm resting / 120bpm walking). Thought this perhaps normal while my heart recovers but had a niggle it was flutter. HR would sometimes get back down to 60 for an hour but increase to 90 again.

Called my EP who asked me to go in for ECG this morning. Nurse confirmed I'm in flutter but EP hasn't called me back. I expect this will now be on Monday.

Has this happened to anyone else? Surely if it was 99% successful it wouldn't come back this soon. I'm praying I self convert but 10 days is a long time.
