Dressler Beats in VT
Report: Ventricular tachycardia 160/min Spontaneous termination Ventricular fusion beats Sinus tachycardia 120/min Comment: The fusion beat during a run of VT is known as Dressler beat12. Note how it is easier to spot fusion beats looking at their r
Atrial Flutter with 1:1 Conduction
Report:Atrial tachycardia (flutter) 202/min 2:1 block (top strip) 1:1 conduction (bottom strips) Rate-dependent left bundle branch block Comment: Note the exact doubling of the ventricular rate in the lower strips. From the rate alone, the rhythm w
Ventricular Tachycardia or Atrial Flutter?
Report:Ventricular tachycardia 250/min Comment:The trace is bizarre enough to qualify for VT; the marked respiratory swing in some leads gives it a multiform appearance. The rate, however, remains uniform and simultaneous leads confirm the basically uni
Tachycardie Préfibrillatoire
Report: Ventricular tachycardia, multiform > 300/min ?Torsade de pointes ?Ventricular flutter Sinus rhythm VEBs ? aberrant(RBBB) junctional premature beats R-on-T phenomenon Comment: This is the fastest spontaneously terminating VT I have seen so fa
Runs of Aberrant SVT
Report: Sinus rhythm Incomplete right bundle branch block SVEBs, some in couplets, of atrial origin SVEBs, single, of junctional origin, dissociated Short runs of atrial tachycardia Aberrant conduction, RBBB type, variable Comment: The QR morphology
SVT or VT?
Report: Broad-complex tachycardia 154/min Comment: The tachycardia has unusual RAD, possibly a qR morphology in V1 and virtually concordant positive precordial pattern; yet it resembles RBBB and there appears to exist a 1:1 atrial activity (best seen as
Dimorphic (Alternating) Ventricular Tachycardia
Report:Ventricular tachycardia 182/min Comment:The rhythm is slightly irregular and, at least in V1, there are two, possibly three, different morphologies; this is, by itself, would be evidence for ventricular ectopic origin. More likely, however, judgin
Cardiac Arrest on 12-lead ECG
Report: Sinus rhythm Triplet of multiform ventricular tachycardia Sustained multiform ventricular tachycardia/VF Inferior infarction, age uncertain Comment: This may or may not be VF; if not, it is at least another tachycardie préfibrillatoire41. Th
Multiform Ventricular Tachycardia
Report: Sinus tachycardia 180/min VEBs, some in bigeminy Multiform ventricular tachycardia 280-310/min Comment: The sinus tachycardia was confirmed on 12-lead ECGs. It is very fast, reflecting both continued pain and hæmodynamic instability. The VE
Cardioverter-Defibrillator During Ventricular Tachycardia
Report:Ventricular tachycardia 133/min Burst of overdrive pacing 160/min Fusion beat Comment:This is the same patient as Case 4, five years later. The ICD does not always work, but the patient is alive, with numerous episodes of VT perhaps rendered les
