Intranodal or intra-Hisian blocks almost always feature escape rhythms with narrow QRS complexes in the mean while infra-Hisian block often presents with wide QRS complex escapes. 1,2. Our patient had CHB with narrow complex junctional escapes as shown in Figure 1. Webb1 mars 2013 · Invasive electrophysiological study was performed to determine cause of syncope. Normal conduction up to the AV node with an AH interval of 79 ms (normal = 55–125 ms) was observed. However, every alternate sinus beat was blocked after the inscription of His deflection (infra-Hisian block). pintar hulk online
