This patient had classic atrial flutter with a cycle length of 240 msec prior to ablation. The P waves were deeply negative in ECG leads II, III, and aVF, and were initially upright in V1. Note ...

With atrial fibrillation, no descrete P waves can be seen, however sometimes coarse "fibrillitory waves" are present. In atrial flutter a "sawtooth" pattern is seen. In MAT there are at least 3 ...
