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
Sotalol Overdose
Report:Sinus rhythm 62/min 2:1 AV block Ventriculophasic sinus arrhythmia Prolonged QT interval 0.58â QTc 0.58â Comment:The blocked alternate P waves are not very obvious, superimposed on prolonged, themselves rather wavy, T waves. Also, alternat
Lean Children of Fat Parents
Report: Sinus arrhythmia ? Sino-atrial exit block, Möbitz I Right bundle branch block Pacemaker escape beats Ventricular fusion beats âNormalisationâ of QRS Comment: Both ânormalâ complexes (one in each strip) and the small RBBB complex (6
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
Bigeminy in Sino-Atrial Exit Block
Report: Sinus rhythm approximately 90/min Left atrial abnormality (LAA) 3:2 Sino-atrial exit block, Möbitz 1 (Wenckebach) Bigeminy Left axis deviation â35o Comment: Bigeminy like this one has to be differentiated from atrial ectopic bigeminy: half
Notched P Wave
Report: Sinus rhythm Left atrial abnormality (LAA) Widely notched P wave Sino-atrial exit block Probable atrial infarction Comment: The wide P wave (0.18â) is produced by an atrial conduction defect, usually involving the interatrial tract (Bachm
Post-Ectopic Sino-Atrial Depression
Report:Sinus rhythm 74/min SVEBs, one RBBB-aberrant Marked post-ectopic SA depression (overdrive suppression) Left bundle branch block Comment:The 7th beatâs Pâ distorts the T wave of the preceding sinus beat. The pause containing the SVEB is more
Sino-Atrial Wenckebach
Report: Sinus rhythm Left atrial abnormality (LAA) 5:4 and 4:3 sino-atrial exit block, Möbitz 1 Normal QRS/T Comment: In each pause, an entire P-QRS-T sequence is missing; the pause itself is less long than two sinus cycles. There is slight accelerat
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
Sinoatrial Block: CVA
Report:Sinus rhythm Sinus pauses - probable Wenckebach exit block Junctional escape beats and rhythm Atrial fusion beats SVEB. Comment:The sinus cycles tend to shorten before the pause, a characteristic of Möbitz 1 (Wenckebach) exit block. There is
