Thyrotoxicosis
Report:Supraventricular tachycardia 215/min Comment:Somewhat unusual first presentation of thyrotoxicosis; not even spectacularly fast. However, following adenosine-induced reversion to sinus rhythm, she remained quite tachycardic (Fig 94a) and thyroid f
Invisible LAHB Causing 2:1 AV Block
Report:Sinus tachycardia 120/min 2:1 AV block Right axis deviation +140o Right bundle branch block Possible old anterolateral infarction Comment:The cause of the RAD may be RVH or old anterolateral MI but the former was certainly not present clinical
Wenckebach AV Block in Marked Sinus Tachycardia
Report: Sinus tachycardia 138/min Second degree AV block, Möbitz 1 Probable acute inferior infarction Comment: It is unwise, generally, to diagnose infarction from rhythm strips, but this one has all three indicative changes of acute infarction: Q wav
Parallel Slopes
Report: Sinus tachycardia 104/min Intermittent second degree 2:1 AV block, possibly Möbitz 2 Intraventricular conduction defect, unspecified (? lead 2 strip) Comment: The tachycardia makes it very difficult to observe any increments in the PR interval
Wenckebach Conduction of Sinus Tachycardia
Report: Sinus tachycardia 116/min SVEB Second degree AV block, Möbitz 1 Comment: Some of the blocked P waves look different in shape from others, due to their position on the preceding T wave. Their timing easily distinguishes them from blocked SVEBs.
Complete Heart Block: Anterior MI
Report: Sinus tachycardia Third degree AV block Ventricular escape beats and rhythm Comment: The slowing of the sinus rate in the forth and fifth strips was ominous, reflecting sinus node hypoxia or ischæmia. The ventricular escapes were slow and unr
2:1 AV Block
Report:Sinus tachycardia 112/min 2:1 AV block Comment:The term "advanced" or "high-grade" AV block is used to describe 50% or less conduction. It is not a useful term except for the fact that it is used! Marriott is right in suggesting the term be used
Isoprenaline Tachycardia
Report: Sinus tachycardia 108/min 2:1 AV block (top) Sinus tachycardia 150/min 2:1 & 3:2 Wenckebach AV block (middle) Sinus tachycardia 165/min (bottom) First degree AV block 1:1 conduction Comment: Isoprenaline helped the bradycardia, but at a pri
Wenckebach AV Block in Marked Sinus Tachycardia
Report: Sinus tachycardia 138/min Second degree AV block, Möbitz 1 Probable acute inferior infarction Comment: It is unwise, generally, to diagnose infarction from rhythm strips, but this one has all three indicative changes of acute infarction: Q wav
