Coronary Sinus Activation and ECG Characteristics of Roof-Dependent Left Atrial Flutter After Pulmonary Vein Isolation
Key result
Coronary sinus activation time ≤39 ms distinguished roof-dependent atrial flutter from mitral annular flutter with 100% sensitivity and 97% specificity.
Why the study?
How do ECG and coronary sinus activation characteristics differ between roof-dependent left atrial flutter and mitral annular flutter in patients post-pulmonary vein isolation?
Population
33 patients post-pulmonary vein isolation with roof-dependent atrial flutter based on activation and…

Cite This Study
Casado-Arroyo et al. (2018) conducted an observational in Roof-dependent left atrial flutter post-pulmonary vein isolation (n=33). Coronary sinus activation and ECG mapping vs. Mitral annular flutter was evaluated on Coronary sinus activation time ≤39 ms to identify roof versus MA flutter. Coronary sinus activation time ≤39 ms distinguished roof-dependent atrial flutter from mitral annular flutter with 100% sensitivity and 97% specificity.
