Phasic Aberrant Conduction in AF: Ashmanâs Phenomenon
Report:Atrial fibrillation with ventricular response 108/min Ashmanâs phenomenon Nonspecific inferior T wave changes Comment:The chest discomfort could be ascribed to AF. In 1947 Gouaux and Ashman published a report of RBBB aberration mimicking VT d
LBBB with Northwest Axis
Report:Atrial fibrillation with ventricular response 98/min Left bundle branch block Axis approx. +240o Comment:The S wave in lead 1 makes the axis extreme right or left (no manâs land); this seems to have the same significance as right axis deviatio
Masquerading and Left BBB: BBBB
Report:Atrial fibrillation with rapid ventricular response 150/min Right bundle branch block Left anterior hemiblock Left bundle branch block Bilateral bundle branch block. Nonspecific ST/T changes Comment:In this case one can diagnose BBBB directly
RBBB & Contralateral Escape Beats
Report: Atrial fibrillation with slow response Right bundle branch block Borderline left axis deviation â30o Ventricular escape beats with left bundle branch block morphology Nonspecific ST/T changes Comment: One instinctively looks (or should look
Intraventricular Conduction Delay
Report:Atrial fibrillation with rapid ventricular response 159/min Intraventricular conduction delay (IVCD), QRS 0.26â Comment:The tracing has some elements of RBBB with marked LAD due to QS in lead 2 and Qr in 3 and aVF. In lead 1, however, the initi
Crying Wolff with Surprising Outcome
Report: Supraventricular, possibly junctional, rhythm 54/min Wolff-Parkinson-White conduction, type âBâ Comment: One cannot be completely certain of the provenance of the atrial impulses; they are flat or biphasic in the frontal plane leads. In V1,
Escape-Capture Bigeminy in AF
Report: Atrial fibrillation High-grade or complete AV block Junctional rhythm 39/min Pacemaker (escape) rhythm Escape-capture bigeminy Left anterior hemiblock (LAHB) Right bundle branch block Anteroseptal infarction, age uncertain ST/T changes con
Jarisch-Bezold Reflex
Report: Atrial fibrillation with slow response Junctional escape beat(s) Comment: There is no observable atrial activity, but the patient had atrial fibrillation since admission. The strips could pass, electrocardiographically, for sinus arrest or atria
Complete AV Block
Report:Third degree AV block Sinus bradycardia 42/min Junctional beats (top strip) Atrial fibrillation Junctional escape rhythm 36/min Pacemaker rhythm 82/min Short QT interval ? digoxin toxicity Comment:The varied atrial activity has no effect on
AF with Regular Response?
Report: Atrial fibrillation Accelerated (idio)junctional rhythm Comment: Verapamil is known to âregulariseâ the ventricular response to atrial fibrillation. Completely regular rhythm, however, implies AV block and the presence of an escape pacemaker
