Let's first consider the heart rate: with a heart rate of 194 beats/min, the heart rate is too low for atrial flutter (1:1) (except in patients who have been pre-treated with medication), and the rate would be unusually high for atrial flutter with 2:1 conduction. What arrhythmia is present?

Complete and durable block across the left atrial (LA) roof can be integral to ablation of persistent atrial fibrillation (AF) and atypical atrial flutter (AFl). The right pulmonary artery (RPA) is in close proximity to the LA roof, and may provide a vantage for epicardial LA roof mapping and ablation.

It is atrial flutter with 2:1 conduction. There are clear flutter waves in lead II across the bottom. In V1, there are upright waves that appear to be P-waves but are not: they are atrial waves and it is typical for atrial flutter waves to be upright in V1, whereas sinus P-waves are biphasic in V1.
