AV Dissociation with Interference
Report:Sinus rhythm 1 Borderline right atrial abnormality (RAA) 1 SVEB 1 Ventricular demand pacemaker rhythm 72/min 2 AV dissociation with interference 2 Fusion beat 2 Nonspecific ST/T changes 1 Comment:The sinus P waves march through the first fo
Delectable Deductive Diagnosis of RBBB/LPHB
Report: Dual chamber pacemaker rhythm 70/min 2 Frontal plane axis –20o 2 Ventricular fusion complexes throughout 3 Probable underlying right bundle branch block with right axis deviation 3 Comment: I make no apologies for the subcontinental flavour of
Rate Hysteresis
Report:Sinus rhythm 1 VEBs, multiform 2 Demand ventricular pacemaker 3 Rate hysteresis 3 Fusion beat (top panel) 1 Comment:The VVI pacemaker takes over after the VEBs; the long cycle it terminates corresponds to a rate 50/min, while the subsequent t
