Not all atrial flutters demonstrate the typical "sawtooth" pattern. During the times of lesser conduction on this ECG, the flutter waves are more apparent. The atrial rate is organized at a rate of ...
When atrial flutter is seen with such a slow ventricular response (in this case, 9:1 conduction), there is concern for underlying complete heart block should the patient be restored to normal sinus ...
The rhythm in Figure 1 has a subtle pattern—a narrow QRS complex with alternating short and long R-R intervals, resulting in paired QRS complexes. Careful observation of V1 in Figure 2 reveals tiny ...
