Idioventricular Rhythm in Complete AV Block
Report: Sinus arrhythmia & bradycardia Junctional rhythm 48/min, also blocked Third degree AV block Idioventricular escape rhythm 10 â 30/min Comment: The (blocked) sinus rhythm is slow and irregular. Eventually it is replaced by somewhat more const
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
Atrial Fusion Beats
Report:Sinus rhythm Junctional ? atrial rhythm Shifting (atrial) pacemaker Atrial fusion beats AV dissociation Probable third degree AV block Pacemaker rhythm 63/min Comment:Again, this is a "trick" question, designed to make one look (in vain) for
Interpolated VEBs in Advanced AV Block
Report: Sinus tachycardia 108/min Second degree, advanced (4:1, 3:1) AV block VEBs, multiform, interpolated Left bundle branch block Comment: The ætiology of the block remained unknown; it could have been due to polyarteritis nodosa through its assoc
Trigeminal Bradycardia
Report: Sinus tachycardia Advanced second degree AV block 9 second pause Junctional escape beats Comment: Some sinus beats are probably conducted, e.g., first two in the top strip. The long pause is terminated by a junctional escape (first beat in the
Advanced AV Block Following VEBs
Report: Sinus rhythm VEBs Triplet of ventricular tachycardia Advanced second degree AV block Comment: The episodes of ventricular standstill all follow the VEBs. The VEBs appear to have retrograde conduction, which may account for sinus rates being
Valsalva ManÅuvre
Report: Top: Sinus rhythm & arrhythmia Blocked SVEB (first pause) Second degree AV block (second pause) Junctional escape beat Bottom: Sinus rhythm & arrhythmia First degree AV block Sinus arrest Comment: The vagal reflex triggered by the inspi
Junctional Bigeminy & Curious ST Elevation?
Report: Sinus arrest Junctional escape rhythm Bigeminy ? reentry ? different junctional foci ? junctional exit block Post-extrasystolic ST segment elevation Comment: The above diagnoses, reasonable as they may sound, were all wrong. The only person a
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.
