Pathophysiologically, J (Osborn) waves are thought to be caused by differences in action potential characteristics between the epicardial and endocardial layers of the heart.
Under the guidance of the three-dimensional atrial geometry (CARTO System, Biosense Webster), endocardial activation mapping demonstrated that the earliest endocardial activation site was in the RAA where the local electrogram was 90 ms prior to the onset of the a wave on reference CS[sub]5-6[Figure 1].
5) Thus, the five year arrhythmia-free survival in non-paroxysmal atrial fibrillation (NPAF) for a single endocardial catheter ablation procedure still remains low and has been reported at 28.
Definity is indicated for use in patients with suboptimal echocardiograms to opacify the left ventricular chamber and to improve the delineation of the left ventricular endocardial border.

The electrophysiology study and endocardial left ventricular electroanatomic activation mapping were performed during VT and identified a focal source of early activation at the mid-portion of the anterolateral LV consistent with an anterolateral papillary muscle VT.
The company's technology is used in the Convergent procedure, a multi-disciplinary therapy in which a closed-chest surgical epicardial ablation is performed, and then complemented by an endocardial catheter ablation performed by an electrophysiologist.
Endothelial NOS is mainly present in the coronary vascular and endocardial endothelium and to a lesser extent in cardiomyocytes.
