    Notes: Sinus Tachycardia with AV Block During VVS. Introduction: Neurocardiogenic (vasovagal) syncope is characterized by hypotension and bradycardia. The presence of sinus tachycardia along with AV block during syncope in patients with neurocardiogenic syncope has not been described previously. Methods and Results: Two female patients (18 and 16 years old) with recurrent syncope and documented sinus tachycardia at the time of syncope are described. Patient 1 had recurrent episodes of syncope. During one of these episodes, which occurred while she was being monitored, sinus tachycardia along with high-grade AV block was seen at the time of syncope and hypotension. Patient 2 had a history of recurrent syncope and seizure. During one of these episodes, she was documented to have ventricular asystole lasting for about 39 seconds. The sinus rate was 480 msec at the beginning, before slowing down to 960 msec prior to restoration of sinus rhythm with 1:1 AV conduction. The same scenario was repeated during head-up tilt testing. Both patients were treated successfully with oral disopyramide and, during a follow-up of 28 months and 9 months, have remained symptom-free. Conclusion: Sinus acceleration along with high-grade AV block during syncope and hypotension can occur in some patients with neurocardiogenic syncope. The exact mechanism of this phenomenon is unclear.

    Transient Complete Atrioventricular Block Following Radiofrequency Ablation of Left Free Wall Accessory Pathway (1998)

    Notes: Abstract We report the case of a forty-six-year-old female with symptomatic WPW syndrome. The accessory pathway was located on the left free wall, for which ablation was attempted from the retrograde aortic approach. The ablation catheter was positioned at the appropriate site on the mitral anulus. A single radiofrequency energy application resulted in complete AV block with no escape rhythm, necessitating ventricular pacing. The AV conduction soon resumed with no evidence of pre-excitation. This phenomenon was thought to be related to trauma to the AV node during catheter entry in to the left ventricle.

    Notes: Thermomechanical controlled processing of concrete reinforcement bars, comprisingquenching and autotempering, produces a microstructural gradient across the diameter - temperedmartensite near to the surface, bainite and/or degenerated pearlite in the intermediate layers andpearlite-ferrite within the core. Since martensite is the strength controlling phase in steels, itsfractional thickness in TMCP bars have beeen correlated to tensile properties. The developedempirical model, helped in revealing that upto a fractional rim of about 20%, volume fraction offerrite-pearlite predominantly influenced the YS, UTS and % elongation, whereas at higherfractions, martensite found to control these properties
