Termination of SVT: Pacemaker Escape
Report:Supraventricular tachycardia 165/min 1 Electrical alternans 2 Termination of paroxysm 0 Atrial escape beat (fusion) 2 Pacemaker escape beat 1 Sinus beat (fusion) 2 VEB (last complex) 1 Nonspecific ST/T changes, possible LVH (R2 = 15 mm) 1
WPW âAâ Mime of Inferoposterior Infarction
Report:Sinus rhythm 68/min Wolff-Parkinson-White type âAâ conduction Comment:The QRS appears narrow and the PR interval normal in several â in fact, most â leads. On the other hand, the latter is completely effaced by a δ wave in V2 and V3. The
Electrical Alternans at 300/min
Report:Supraventricular tachycardia 300/min Electrical alternans Comment:At fast rates, electrical alternans has no connotation of cardiac failure. It can be quite transient: below (Fig 73a) is a trace at only slightly slower rate, without alternans. T
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
Lown-Ganong-Levine Syndrome
Report:Sinus rhythm 65/min LGL conduction PR interval 0.10â Borderline inferior T wave changes Comment:The commonly accepted explanation for the short PR interval is partial or complete AV nodal bypass by paranodal fibres inserting into the bundle o
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 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
A Unique LBBB Aberrancy
Report: Probable supraventricular tachycardia 182/min Right axis deviation +110o LBBB Comment: The QRS complexes in V1-2 take almost 0.08â to reach the nadir of their S waves, but this is not immediately obvious on inspection. The initial QRS in V1 i
Pædiatric SVT
Report: Orthodromic atrioventricular re-entrant tachycardia 333/min Possible flutter with 1:1 conduction Left bundle branch block ?Wolff-Parkinson-White syndrome ( see below) Comment: The rate is very fast, but an infantâs flutter can be much faster
SVT: Pre-existing RBBB/LAHB
Report: Tachycardia 102/min ? origin Onset of supraventricular tachycardia 190/min Right bundle branch block Left anterior hemiblock Anterior infarction, probably old Comment: Frontal plane axis of â90o and the monophasic R wave in V1 bode ill for
