WebThe bypass tracts of the WFW syndrome may be situated anywhere along the AV ring. Accurate localization of such tracts has in the past been largely effected by electrophysiologic studies, particularly epicardial mapping. During recent years, however, criteria for localization of the bypass tracts fr … WebJul 17, 2013 · Diabetes is known to cause pathologic changes in the GI tract and produce malabsorption.¹¹⁻¹³ Gastroparesis is the best known complication, but malabsorption occurs in some patients with diabetes.¹¹ GI surgery, such as gastric bypass for weight control, is now commonplace and may cause malabsorption of opioids.
WebTwo patients also had an AV bypass tract, with anterograde conduction over the fasciculoventricular pathway during orthodromic AV reentrant tachycardia. After ablation of the AV pathways, the ECG during sinus rhythm and the electrophysiologic study showed ventricular preexcitation due to a fasciculoventricular bypass tract inserting into the ...
