Phasic T Wave Inversion
Report: Sinus arrhythmia Respiratory swing of QRS & T wave axis Comment: This is not uncommonly seen in right precordial leads, including the monitor leads. It may be significant if only one or two cycles are recorded on a 12-lead ECG. See Case 211. 23
Long Wenckebach Pauses
Report: Sinus rhythm 56 â 66/min Second degree AV block, Möbitz 1 3:2 conduction with bigeminy Left ventricular hypertrophy voltage Comment: Wenckebach pauses are normally less than two sinus cycles in length. When, as here, they coincide with the
Respiratory & Ventriculophasic Sinus Arrhythmia
Report: Sinus rhythm Respiratory sinus arrhythmia Ventriculophasic sinus arrhythmia Second degree AV block, Möbitz 1 Period of 2:1 conduction + one 5:4 cycle LVH with ST/T changes ± digoxin effect Comment: The ventriculophasic effect â P-P inter
Scary Pauses in Congenital AV Block
Report:Sinus arrhythmia Third degree AV block Junctional escape rhythm 5.52" pause Comment:Most patients with (idiopathic) congenital heart block have a reasonably fast junctional pacemaker and can get by without pacing. Presence of prolonged pauses m
The Race Is Not to the Swiftâ¦
Report: Sinus rhythm & arrhythmia 58 - 74/min. Left anterior hemiblock (LAHB). Right bundle branch block (RBBB). Second degree AV block, 2:1, rate-dependent. Comment:The patient has, in addition to obvious conduction problems, an abnormally marked s
Sinus Arrhythmia or SA Exit Block?
Report: Sinus rhythm Sino-atrial exit block Comment: All the groups display the characteristic acceleration before the pause. This is the hallmark of Wenckebach (Möbitz 1) sino-atrial exit block, only slightly modified by true (respiratory) sinus arrhy
Let the Sleeping Dog Lie?
Report:Sinus arrhythmia 45 - 68/min Second degree AV block Two blocked P waves Comment:It is disconcerting to see a spontaneous 3.7" pause, but (i) the patient had a recent inferior MI and (ii) remained asymptomatic during similar episodes while awake.
