Fusion Beats Starting Runs of VT
Report:Sinus arrhythmia Ventricular tachycardia 132-185/min, non-sustained25 1:1 retrograde conduction Fusion beat Comment: The fusion beat starting the paroxysm of VT is diagnostic of the ventricular origin of the latter. Dressler beats are fusion
Dressler Beats in VT
Report: Ventricular tachycardia 160/min Spontaneous termination Ventricular fusion beats Sinus tachycardia 120/min Comment: The fusion beat during a run of VT is known as Dressler beat12. Note how it is easier to spot fusion beats looking at their r
Cardioverter-Defibrillator During Ventricular Tachycardia
Report:Ventricular tachycardia 133/min Burst of overdrive pacing 160/min Fusion beat Comment:This is the same patient as Case 4, five years later. The ICD does not always work, but the patient is alive, with numerous episodes of VT perhaps rendered les
Two Wrongs Making Two Rights!
Report: Sinus tachycardia 110/min Left bundle branch block Left axis deviation Runs of ventricular tachycardia 150 - 160/min AV dissociation Ventricular fusion beats Comment: This is from Schamroth himself: two wrongs sometimes make a right60. The t
R-on-T VT?
Report: Sinus rhythm Left bundle branch block Ventricular fusion beat (8th complex) Ventricular tachycardia (flutter)188/min Comment: The answer to the question is: none - no significance! It looks, at first, that the flutter starts with an R-on-T VE
Runs of Ventricular Tachycardia
Report: Runs of monomorphic ventricular tachycardia 155/min Spontaneous termination Atrial and junctional escape beats Sinus tachycardia SVEBs ?multifocal atrial tachycardia Intraventricular conduction defect, possibly LBBB Comment: The patient's ar
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
AIVR & Retrograde Conduction
Report: Sinus arrhythmia VEB (second complex in the top strip) Atrial (?junctional) escape complex (9th in the top strip) Accelerated idioventricular rhythm 86-89/min Retrograde conduction Fusion beats Comment: Typically, the retrograde 1:1 conducti
Sinoatrial Block: CVA
Report:Sinus rhythm Sinus pauses - probable Wenckebach exit block Junctional escape beats and rhythm Atrial fusion beats SVEB. Comment:The sinus cycles tend to shorten before the pause, a characteristic of Möbitz 1 (Wenckebach) exit block. There is n
Empty Wenckebach Pauses
Report: Sinus rhythm SVEB (second QRS, bottom strip) Second degree AV block, Möbitz 1 Junctional beats, non-conducted ?Reentry beats of sinus origin Atrial fusion beats, non-conducted Comment: In the upper strips, the Wenckebach sequences are termin
