Sixty-three episodes of isthmus-dependent atrial flutter (AFL) in 55 patients were studied to characterize variations in flutter wave morphology and to investigate the mechanisms of the atypical flutter waves on surface ECG. The activation patterns of coronary sinus (CS) and their relationship with flutter wave morphology on the ECG were analyzed. In 46(More)
Protein motifs, which are specific regions and conserved regions, are found by comparing multiple protein sequences. These conserved regions in general play an important role in protein functions and protein folds, for example, for their binding properties or enzymatic activities. The aim here is to find the existence correlations of protein motifs. The(More)
OBJECTIVES To investigate the value of changes in P wave morphology and duration detected by surface electrocardiogram (ECG) during proximal coronary sinus (PCS) and low lateral right atrial (LLRA) stimulation as a marker for complete bidirectional isthmus conduction block in the procedure of typical atrial flutter ablation. METHODS Morphology, duration,(More)
Radiofrequency (RF) ablation is a widely accepted and ideal therapeutic tool to cure some tachycardias. The occurrence of complications varies depending on the procedure being performed. Sudden unexpected prolonged asystole is rare for most ablation procedures and the underlying mechanisms remain unclear. A case of sudden prolonged asystole induced by RF(More)
