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 0.32” Left bundle branch block Comment: The last cycle of the VT is shorter than others, indicating an exit blo

Multiform & Monomorphic Ventricular Tachycardia

Report: Multiform ventricular tachycardia 180-210/min Comment: The tachycardia becomes (or looks) uniform in some leads, as is often the case in both torsades de pointes and other types of multiform ventricular tachycardia. It starts with what Marriott a

Tachycardia with Complete & Incomplete LBBB

Report:Atrial flutter with 2:1 AV block. Alternating complete & incomplete LBBB. Primary T wave changes. Comment:This is another form of bidirectional tachycardia. It is also an example of double 2:1 block: one in the AV node (for atrial flutter) and a

Ventricular Tachycardia Rightly (Mis)diagnosed

Report:Ventricular tachycardia 170/min Comment:There is nothing against the diagnosis of VT in this trace, and a lot in its favour: monophasic R waves in V1 with left rabbit ear taller than the right and QRS duration over 0.14” (in basic RBBB morphology)

Fatal Digoxin Toxicity

[!xe "Digoxin toxicity:VT:fatal DCC" \i!] Report:Fascicular tachycardia 178/min. Comment:The most likely diagnosis is a fascicular VT, consistent with digoxin toxicity. In fact the Cardiology Registrar knew that serum digoxin was in the toxic range (3.9

Reentry (Echo) Beats of Ventricular Origin

Report: Sinus rhythm VEBs Bigeminal Couplets & triplets Retrograde VA conduction First degree VA block Wenckebach conduction Reentry Post-ectopic sino-atrial depression Junctional escape beats Comment: There are two reentry beats: third last in

Double Coupling of VEB Couplets

Report: Sinus arrhythmia 85 – 109/min Frequent VEBs Accelerated idioventricular rhythm (AIVR) approx. 65/min Comment: The VEBs come in two morphologies, the tall and the stubby, in the L2 rhythm strip. The tall ones are premature, with a fixed coupling

104. 88 year old patient with permanent pacemaker and ischæmic cardiomyopathy.

Atrial Pacing & Intercalated VEBs

Report: Atrial pacemaker rhythm VEBs, intercalated (interpolated) Comment: The VEBs show the diagnostically important left rabbit ear and different initial vector from the paced beats. They also prolong the subsequent A-R intervals through concealed ret

Ventricular or Another Atrial Tachycardia?

Report: Ventricular tachycardia 178-180/min Comment: The tachycardia basic LBBB morphology with right axis deviation; the nadir of the S wave in V1 came after more than 0.06”. It looked like VT: RAD with LBBB has never been reported as aberrancy8. This c
