Old Anterior MI in VT & VEBs
Report:Ventricular tachycardia 200/min Probable old anteroseptal infarction Comment:The VT has a deep Q wave, QrS morphology and associated ST elevation resembling an infarct pattern. Sometimes the previous infarct is only visible when revealed by VEBs.
Semiventricular Tachycardia
Report:Sinus rhythm 61/min. First degree AV block (PR 0.24"). VEBs, interpolated, in bigeminy. Semiventricular tachycardia 122/min. Probable old anterior MI. Comment:The tachycardia consists of sinus rhythm + interpolated VEBs. The term semiventricul
Broad-Complex Ventricular Tachycardia
Report:Ventricular tachycardia 163/min Comment:This example would be difficult to assign LBBB- or RBBB-like status in view of the RS complex in V1. Nevertheless, the QRS duration of approximately 0.20â is in excess of 0.16â required for LBBB-like VT,
Ventricular Tachycardia: RV1
Report:Ventricular tachycardia 220/min. Comment:The patient's age and the relatively fast rate must have influenced the first choice of aberrancy in the Casualty report. The "VT with underlying WPW", however, suggests diagnostic skills beyond electrocard
SVT or Verapamil-Responsive VT?
Report:SVT or VT 156/min. Right bundle branch block. Left anterior hemiblock. Comment:The tachycardia has a typical RBBB/LAHB morphology consistent with aberrantly conducted SVT. The rate varies slightly; this has no diagnostic significance. The probl
Verapamil-Sensitive Ventricular Tachycardia
Report: Ventricular tachycardia 152/min Comment: This arrhythmia resisted flecainide, sotalol, digoxin and adenosine; verapamil slowed the rate significantly (Fig 82a) and allowed partial sinus captures, but could not abolish it. The cardioversion was ef
SVT with LBBB
Report: Supraventricular tachycardia 152/min Left bundle branch block Comment: The rS complexes in lead V1 are perfectly ânormalâ LBBB complexes in that the initial R wave is narrow, the S downstroke is sharp and the upstroke slurred. The frontal pl
Dangerous WPW Syndrome
Report: Atrial fibrillation Rapid response 240-300/min Anomalous (WPW) conduction, type âBâ Comment: If the observed cycle lengths during atrial fibrillation are less than 0.25â (250 milliseconds sounds more âlearnedâ in this context), the p
Torsade de Pointes
Report: Torsade de pointes ventricular tachycardia 270/min Comment: The patient became understandably restless in the middle of the recording. This is a rare example of 12-lead ECG during torsade de pointes tachycardia. It is immediately apparent (movem
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
