Bigeminal Ventricular Tachycardia
Report:Ventricular tachycardia 173/min Alternating cycle length Comment:The patient had presyncopal paroxysms of VT, though to be SVT by many because of its relatively narrow QRS. They were even more convinced when, in Casualty, he reverted to sinus rhy
Bidirectional AIVR
Report: Alternating (bidirectional in some leads) accelerated idioventricular rhythm Comment: At first glance, the trace suggests RBBB and ventricular bigeminy. It is quite regular and no definite atrial activity can be discerned, except for the wrinkle
Fusion Terminating AIVR
Report: Sinus rhythm 74 â 80/min Accelerated idioventricular rhythm 69 â 74/min Ventricular fusion beat Comment: The AIVR accelerates, but to no avail: the faster sinus rhythm takes over by the middle of the recording. Between the two is a typical
LBBB-like Ventricular Tachycardia
Report: Ventricular tachycardia 168/min Comment: Some would say that the precordial pattern is that of negative concordance. A purist would point out that there are small R waves in V2 or V6; the complexes are not all completely negative. This fortunatel
Bigeminy or Quadrigeminy?
Report: Sinus rhythm approx. 54/min First degree AV block, variable VEBs, bigeminal Concealed retrograde conduction Pacemaker escape beats Comment: This is an allorhythmia, a repetitive sequence of (in this case) four beats. The VEBs themselves are,
VEB couplets: Two for the Price of One
Report: Sinus rhythm 78/min VEBs, frequent, some in couplets (pairs) Poor R wave progression Nonspecific ST/T changes Comment: The VEBs have typical qRRâ morphology, with left rabbit ear taller than the right; the pauses are fully compensatory. The
No Response to DC Cardioversion
Report: Probable atrial flutter or fibrillation Non-sustained monomorphic ventricular tachycardia 160/min Inferior infarction ?age Comment: The patient was one of those surgical disasters that attract multiple medical consultations in the hope of expla
Multiform Ventricular Tachycardia
Report: Atrial fibrillation Runs of multiform ventricular tachycardia 150 â 180/min Right axis deviation +165o Probable right bundle branch block Acute inferior infarction Comment: There are only four pure supraventricular beats to be seen â two
Positively Concordant Trigeminy
Report: Sinus tachycardia 130/min VEBs in trigeminy Left atrial abnormality Minor T wave changes Comment: The VEBs are monophasic R complexes from V1 through V6. This is diagnostic of ventricular ectopic origin. A regular run of such beats, however, w
LBBB-Like VT in Patient with RBBB
Report:Ventricular tachycardia 178/min LBBB morphology with right axis deviation Comment:This is, morphologically, right ventricular outflow tract (RVOT) tachycardia, with LBBB and marked right axis deviation (not seen in aberrant conduction8). The morp
