This study investigated the effectiveness of correlation waveform analysis for identifying different ventricular electrogram morphologies of multiple VTs in the same patient. Patients with implantable antitachycardia devices are commonly subject to the occurrence of more than one distinct monomorphic VT. Each of these VTs may have unique therapeutic alternatives for termination. VTs with identi...

OBJECTIVES We assessed the effects of the adenosine triphosphate (ATP)-sensitive potassium channel opener, nicorandil, on ATP- and verapamil-responsive ventricular tachycardias (VTs). BACKGROUND Adenosine- or ATP-sensitive VTs are thought to be due to a nonreentrant mechanism, presumably delayed afterdepolarization. We suggest that this potassium channel opener may suppress ATP- and verapamil...

Vitreomacular traction syndrome (VTS) is a vitreoretinal interface abnormality. The disorder is caused by incomplete posterior vitreous detachment with persistent traction on the macula that produces symptoms and decreased vision. Most symptomatic eyes with VTS undergo a further decrease in visual acuity. Spontaneous complete vitreomacular separation occurs infrequently in eyes with VTS. Surgic...

Noise robustness is a challenging problem when automatic speech recognition (ASR) system is deployed in real life applications. This report examines techniques to improve the robustness of ASR systems. Particularly, we focus on a group of model-based noise robust techniques, called vector Taylor series (VTS) method, that adapt the acoustic model of ASR systems towards noisy test data using the ...

This document is not a candidate for any level of Internet Standard. This document specifies the Voucher Trading System Application Programming Interface (VTS-API), which assumes that the VTS plug-in is trusted by its user. The application making calls to VTS-API ought to authenticate the VTS plug-in and securely bind the plug-in with the VTS provider information specified in the Voucher Compon...
