Poor Manâs Exercise Test
Report: Sinus rhythm VEBs, multiform, some interpolated Post-ectopic repolarisation changes ST segment depression Post-ectopic depolarisation changes Rate-dependent right bundle branch block Comment: The presence of intermittent RBBB somewhat sp
VEB-Induced AV Block
Report: Sinus rhythm. VEBs Second-degree AV block, advanced. Junctional escape beats. Intraventricular conduction delay, QRS 0.12". Comment: All the occurrences of the AV block follow the VEBs. This is âan extremely rare phenomenonâ, with only th
Another Variant Form of Bidirectional Ventricular Tachycardia
Report: Bidirectional ventricular tachycardia 184/min Comment: Like in the preceding case, lead V1 has basic LBBB morphology. This patient, with known pre-existing LBBB, received adenosine for presumptive SVT, without effect. Sotalol, 80 mg IV, abolished
Atrial or Ventricular Fibrillation?
Report: Top: Atrial fibrillation with third degree AV block, or ventricular fibrillation Ventricular standstill Middle: Atrial fibrillation Third degree AV block Junctional rhythm 68/min Bottom: Sinus rhythm 98/min Third degree AV block Junction
Slow Bidirectional Tachycardia
Report: Bidirectional tachycardia 104/min Retrograde VA conduction Junctional escape beats AV dissociation Sinus rhythm 95 â 98/min Overdrive (post-ectopic) SA suppression Comment: The rhythm is obviously bigeminal, with narrow rSRâ complexes
Run of Ventricular Tachycardia
Report: Sinus rhythm 97/min VEBs Ventricular tachycardia 160/min AV dissociation Left atrial abnormality (LAA) First degree AV block PR 0.32â Left bundle branch block Comment: The last cycle of the VT is shorter than others, indicating an exit b
Atrial to Ventricular Fibrillation
Report: CPR massage artefact throughout Supraventricular bradycardia, probably atrial fibrillation with slow response ST segment elevation consistent with infarction or ischæmia VEB Ventricular fibrillation Comment: The CPR artefact during AF mean
Ventricular Flutter
Report: Top: Ventricular flutter 300/min Middle: Accelerated idioventricular (?junctional) rhythm 78/min Sinus capture beats Probable AV dissociation Bottom: Atrial tachycardia 113/min Comment: In ventricular flutter, the distinction between QRS,
VT or SVT in a Patient with Known LBBB?
Report:Ventricular tachycardia 174/min. Comment:The QR morphology in lead V1, however, is that of VT, unless there was a previous anteroseptal infarction. The marked LAD -90o is neither here or there, diagnostically. Interestingly, a recent study using t
Complex Complex of Complex Complexes
Report: Ventricular (fascicular) tachycardia 139/min Retrograde VA block , Möbitz 1 Incomplete Wenckebach sequences Reentry (echo) beats of ventricular origin Comment: As shown on the laddergram below, the longest retrograde RP interval in each tripl
