Intraventricular reentry with narrow QRS complex
Intraventricular reentry with narrow QRS complex is a scholarly work, published in 1980 in ''Circulation''. The main subjects of the publication include electrical conduction system of the heart, left bundle branch hemiblock, reentry, QRS complex, medicine, heart arrhythmia, reentrancy, refractory period, catheter ablation, cardiology, right bundle branch block, anatomy, bundle branch block, cardiac resynchronization therapy, bundle branch, bundle, and internal medicine. The authors reached this conclusion because 1) reentry occurred within a narrow range of V1V2 intervals and was dependent upon critical retrograde His-Purkinje conduction (V2H2) delays; 2) reentry did not occur when the V2 impulse blocked retrogradely within the His-Purkinje system below the site of His bundle recording; 3) the QRS duration of V3 was less than 90 msec; and 4) in two-thirds of the patients, the HV interval of V3 was the same as that of sinus beats..
