When mutiple atrial tachycardias coexist, ablation of an individual isthmus may lead to a seamless transition (without significant changes in surface ECG or coronary sinus activation) to a second rhythm. The isthmus block could go unnoticed leading to continued unnecessary ablations.

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.

Since the rate of atrial activity with flutter in adults is most often very close to 300 /minute ( ie, usual range for atrial activity ~250-350/minute ) — AFlutter with 2:1 AV conduction typically results in a regular ventricular rate of ~140-160/minute.
