Background— Recurrent ventricular tachycardia (VT) is an important cause of mortality and
morbidity late after myocardial infarction. With frequent use of implantable cardioverter-…

ECG Localization of Accessory AV Pathways. Introduction: Delta wave morphology correlates
with the site of ventricular insertion of accessory AV pathways. Because lesions due to …

Background Typical atrial flutter (AFL) results from right atrial reentry by propagation through
an isthmus between the inferior vena cava (IVC) and tricuspid annulus (TA). We postulated …

Background Differentiation between ventriculoatrial (VA) conduction over an accessory AV
pathway (AP) and the AV node (AVN) may be difficult, especially in patients with a septal AP. …

Background : Radiofrequency catheter ablation is used to treat recurrent ventricular
tachycardia (VT). Objectives : This study evaluated long-term safety and effectiveness of …

Background The purpose of this study was to determine how often accessory atrioventricular
(AV) pathways (AP) cross the AV groove obliquely. With an oblique course, the local …

The abnormal development of the tricuspid valve in patients with Ebstein's anomaly results
in several activation abnormalities including delayed intraatrial conduction, right bundle …

Background— At the mitral annulus–aorta (MA-Ao) junction, the left atrium is continuous
through the subaortic curtain with the musculature of the anterior mitral leaflet. Under …

Background— During right atrial stimulation, the anterior and posterior approaches provide
inputs to the atrioventricular (AV) node. The purpose of the present study was to determine …

Background and Objectives Recent observations indicate that cannabis use can result in
cardiovascular complications including arrhythmias. We studied the relationship between …
