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
Double, Perhaps Triple Tachycardia
Report:Bidirectional tachycardia 158-162/min[! XE "Bidirectional tachycardia" \t "See Ventricular tachycardia, bidirectional" !] Suggestive of digoxin toxicity Dissociated atrial tachycardia with block Comment:This is the classical form of bidirectiona
Idiopathic Ventricular Tachycardia
Report: Ventricular tachycardia 181/min Comment: The rate is made irregular by the presence of shorter cycles, as in the Case 2 or Case 61; this is no impediment to the diagnosis of VT. As in the Case 2, the QRS morphology is diagnostic of an ectopic ven
Another Irregular Monomorphic Ventricular Tachycardia
Report: Ventricular tachycardia 152/min Comment: Marked cycle length irregularity is uncommon in sustained monomorphic VT, especially at faster rates, except at the onset or termination of the paroxysm58. Nevertheless, slight variation in cycle length is
Shocking VT Cheating the Paddles
Report: Ventricular tachycardia 210/min Spontaneous termination Sinus rhythm Left atrial abnormality (LAA) VEBs Acute anterior infarction Movement artefact Leads V2-3 missing Comment: The tracing is rather chaotic, secured in a hurry on a sick pat
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
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
Positive Concordant Precordial Pattern in VT
Report: Ventricular tachycardia 175/min Comment: The diagnosis depends on: - concordant (positive) precordial pattern - monophasic R wave in V1 - AV dissociation - known pre-existing LBBB62 Below (Fig 67a) is his 12-lead ECG 3 hours earlier, in mult
Negative Concordant Precordial Pattern in VT
Report: Ventricular tachycardia 170/min Comment: All the chest leads show negative QRS complexes. In VT, this used to be one of the criteria distinguishing it from aberrantly conducted SVT; now only positive concordance is still held valid as a VT criter
SVT with Pre-Existing Left Bundle Branch Block
Report:Supraventricular tachycardia 200/min[! XE "Supraventricular tachycardia:LBBB:QRS0.16\"" !] Northwest axis +230o Small voltage in frontal leads Left bundle branch block Comment:This is a difficult trace to diagnose with certainty: the main featu
