Mechanism of QRS electrical alternans.
In patients with latent dual atrioventricular nodal pathways a 2:1 ventriculoatrial block often occurs during ventricular pacing and is generally associated with the concomitant appearance of QRS alternans. This type of QRS alternans is related to retrograde conduction, and a concealed retrograde conduction in the His Purkinje system could explain the QRS alternans. A case that confirms the hyp...
متن کاملChanging QRS Morphology: What is the mechanism?
ECG in sinus rhythm with ventricular preexcitation and changing QRS morphology was seen that was initially interpreted as the multiple accessory pathway from elsewhere. (Figure 1A). The following mechanisms are potentially involved in the electrogenesis of changing QRS morphology in WPW syndrome: 1) multiple accessory pathways1; 2) simultaneous occurrence of aberrant atrioventricular conduction...
متن کاملWide QRS tachycardia. What is the mechanism?
A 70-year-old gentleman was referred for radiofrequency catheter ablation of wide QRS tachycardia that was not terminated with intravenous adenosine. Twelve-lead ECG was normal during sinus rhythm and transthoracic echocardiography demonstrated no evidence of structural heart disease. The electrophysiological study showed a normal AH interval of 104 m and HV interval of 45 m during sinus rhythm...
متن کاملAtrioventricular Conduction System in Left Bundle - Branch Block with Normal QRS Axis
In nine patients with left bundle-branch block (LBBB), normal QRS axis, and normal P-R interval, atrial, His bundle, and ventricular electrograms were recorded. The extrastimulus method was utilized to determine the relative refractoriness of the various components of the atrioventricular conducting system. The functional refractory period (FRP) of the A-V node was normal in all but one patient...
متن کاملAn irregular, narrow QRS complex tachycardia with ventriculoatrial block: what is the tachycardia mechanism?
A 57-year-old woman underwent an electrophysiology procedure because of a 19-year history of recurrent palpitations. Typical AV nodal reentrant tachycardia that had a cycle length of 460 msec was induced by ventricular pacing. Slow pathway ablation was attempted using a combined anatomical and electrogramguided approach. After an application of radiofrequency energy associated with junctional e...
