Electrophysiological and epicardial mapping studies are described in a patient without pre-excitation who had intractable recurrent paroxysmal supraventricular tachycardia. Electrophysiological studies revealed fixed VA conduction times during both rapid ventricular pacing and coupled ventricular stimulation. Catheter mapping of atrial activation during retrograde conduction and during induced ...
The detection and identification of metal items and, in particular weapons, of linear size ≥ 10 cm, concealed upon the human body, is demonstrated as being entirely feasible by using a phased array of suitably ultra wide band transceivers. The complex natural resonances and especially the fundamental resonance, are excited by ultra wide band, stepped frequency continuous wave illumination of th...
Background and purpose: Preliminary studies have been established to examine the cardiotonic effect of Citrus bigaradia extract, by implenenting various mechanisms. The functional protective role of this plant against supraventricular tachyarrhythmia remains to be determined.The present study is designed to assess the role of hydroalcoholic extract of Citrus bigaradia by modifing the electrop...
INTRODUCTION Isolated diastolic potentials have been found to be helpful in identifying critical sites for ablation of ventricular tachycardia (VT) in patients with coronary artery disease. However, discrete potentials that occur during systole have not been previously described. The purpose of this study was to determine the significance of discrete systolic potentials during VT in patients wi...
In authorization-transparent access control, users formulate their queries against the database schema rather than against authorization views that transform and hide data. The Truman and the Non-Truman are two approaches to authorization transparency where in a Truman model, queries that violate the access restrictions are modified transparently by the system to only reveal accessible data, wh...
Tropical cattle ticks (Boophilus microplus) are the most important ectoparasites that have the impact on livestock development in Thailand due to their responsible for severe economic losses through direct damages of blood feeding and as important pathogen vectors. Acaricides have been used extensively to control ticks with partial success. However, this approach suffers drawbacks such as selec...
