In atrial flutter there is usually either a fixed ratio of F/QRS waves (2 : 1, 4 : 1) or a group beating due to a “patterned” ventricular response (e.g., 2 : 1-4 : 1). In cases of variable block, you are likely to see the exact RR interval of a given...

The anatomic bases of these tachycardias must be defined, to guide appropriate treatment. Atrial flutter is a mere description of continuous undulation on the ECG, and only some strictly defined typical flutter patterns correlate with right atrial macroreentry bounded by the tricuspid valve, terminal...
AIMS. To devise effective preventive measures, a profound understanding of the evolving patterns and trends in atrial fibrillation (AF) and atrial flutter (AFL) burdens is pivotal. Our study was designed to quantify the burden and delineate the risk factors associated with AF and AFL across 204 ...

initial success rates for ablation may vary from 40% to 80%, according to most studies over intermediate term (3–5 year) follow-up.1The most common cause of recurrence after prior ablation presents asatrial fibrillation, although incidentatrial tachycardiaoratrial flutterrelated to both previously...
