Brain-Stem CVA: SA Wenckebach
Report:Sinus rhythm 56 â 100/min Sino-atrial exit block, Möbitz 1 Minor T wave changes Lead V4 missing Comment:At first, seeing the typical grouping with acceleration before the pause, one thinks of AV Wenckebach. But there is no PR interval prolon
Neostigmine Toxicity
Report:Sinus rhythm 3:2 sino-atrial exit block Nonspecific T wave changes Comment:The patient was paralysed by vecuronium for a CAT scan after a traffic accident; she was brought back to Casualty and the relaxant was reversed with 5 mg neostigmine and
Sino-Atrial Wenckebach
Report:Sinus rhythm Sino-atrial exit block, Möbitz 1 Left atrial abnormality (LAA) AV block, Möbitz 1, incomplete sequences Prolonged QT interval Comment:This is an example of one form of block preventing the full expression of another: the AV nod
Sino-Atrial Exit Block
Report:Sinus rhythm 52 â 54/min Sino-atrial exit block Bigeminy Nonspecific T wave changes Comment:There are two long cycles. One is slightly longer, the other slightly shorter than twice the preceding P-P cycle. Allowing for some sinus arrhythmia,
Sino-Atrial Exit Block
Report:Sinus rhythm 74/min 3:2 sino-atrial exit block Bigeminy Negative U waves in lead 1 Comment:The same comments can be made here as for the preceding Case 93. It, too, could have Möbitz 2 mechanism. Below (Fig 94a) is another trace, with long cy
