Type I second-degree atrioventricular (AV) block describes visible, differing, and generally decremental AV conduction. The literature contains numerous differing definitions of second-degree AV block, especially Mobitz type II second-degree AV block. The widespread use of numerous disparate definitions ...
We report a unique case of Mobitz Type 1 second-degree atrioventricular (AV) block, known commonly as Wenckebach, due to hyperkalemia. The patient's symptoms and electrocardiogram (ECG) evidence of Wenckebach block resolved with lowering of serum potassium levels, with subsequent ECG showing first-...
Background: Second-degree AV block, Mobitz type I is frequently a vagally-mediated phenomenon which occurs at the level of theAV node. Case: A 63-year-old woman presented initially to theurologyservice to undergo a rightureteroscopyandlaser lithotripsyof a 1.1 cm right-sidednephrolith. She had...

Electrophysiologic studies in one patientwith spontaneous 2:1 atrioventricular block and variable PR intervals revealed two sites of conduction block. Typical 4:3 A-V nodal Wenckebach was present in addition to Mobitz type II infra-His block. The HV of conducted complexes was 120 msec and the ...
The present study was designed to gain insights into the mechanism and potential clinical relevance of CLA by comparing computer simulations of tachycardia to directly observed behavior in a canine model of AV reentrant tachycardia (AVRT), The computer model was based on the......

These equations may be clinically useful for assessing whether a nonfriggering P wave resulted from Wenckebach type block or atrial undersensing and for the more complicated interval analysis in DDDR pacing with rate responsive AV delays and postvenfricular atrial refractory periods....
a total of 144 Wenckebach cycles in the AV node and 118 Wenckebach cycles in the His-Purkinje system were analysed to determine the incidence of typical and atypical Wenckebach periodicity, with particular emphasis on one variant of atypical Wenckebach that may simulate a Mobitz type II block. Th...
(0.48～0.50 sec).This finding indicates the existence of ectopic Ⅱ° exit block.The P′—R intervals are found to be longthened progressively and R—R intervals shortened progressively.These indicate the Wenckebach type Ⅱ°A-V block.In addition,P′ waves appearing in between sinus P and ...
