Evidence of concealed atrioventricular conduction in man.
THE TERM "concealed conduction" was introduced by Langendorfl to describe the phenomenon of entry of an electrical impulse into the A-V node without complete transmission but with modification of conduction of a subsequent impulse. This concept unified diverse observations of earlier years concerning disturbances of A-V transmission2-4 and clarified the mechanisms of many arrhythmias.5 6 Subseq...
متن کاملCASE REPORT Mechanism of Reciprocating Tachycardia Initiated During Sinus Rhythm in Concealed Wolff-Parkinson-White Syndrome Report of a Case
Reciprocating tachycardia in a patient with a leftsided atrioventricular accessory pathway (AP) (Kent bundle, type A) capable only of ventriculo-atrial (V-A) transmission is described. The V-A AP is established as an essential link of the tachycardia circuit, as evidenced by: 1) retrograde atrial activation of the left atrium (LA) 60 msec or more before the low and high right atrium during reci...
متن کاملCASE REPORTS Concealed Nonparoxysmal Junctional Tachycardia
Electrophysiologic studies were performed in a patient who had an apparently uncomplicated complete trifascicular block. His bundle recordings revealed atrioventricular dissociation with: 1) an atrial rate of 58 beats/min, 2) an idioventricular escape rate of 45 beats/min, and 3) nonparoxysmal junctional tachyeardia (His bundle rhythm) at a rate of 65-85 beats/min. The latter arrhythmia was ele...
متن کاملConcealed primary aortic sarcoma induced hypertensive encephalopathy resulting from a thoracic aortic occlusion: a case report
Primary aortic sarcoma is a rare condition that is frequently associated with distal embolization. In addition, growth characteristics of primary aortic sarcoma lead to the narrowing of the involved aortic lumen. A 72-year-old Korean male with primary aortic sarcoma showed progressive unexplained blood pressure elevation that didn't improve with additional antihypertensive drug therapy. Because...
متن کاملRe-entry due to manifest and concealed. His bundle ectopic systoles. Report of a case.
Concealed (C) His bundle ectopic systoles (H') have been shown in man to give rise to first and second degree atrioventricular (A-V) block and to simulate nonconducted atrial premature beats (P'). This report outlines a hitherto undescribed electrophysiologic consequence of H' in a 69-year-old man with arteriosclerotic heart disease and a Wenckebach type second degree A-V block in the His-Purki...
