Onset of Retrograde Conduction
Report:Top: Sinus tachycardia 104/min VEB Monomorphic ventricular tachycardia 152/min Retrograde conduction Bottom: Sinus tachycardia 110/min Fusion VEBs in bigeminy Monomorphic ventricular tachycardia 150/min Retrograde conduction Comment:In bo
March of Rosenbaumâs Extrasystoles
Report:Sinus rhythm VEBs Runs of non-sustained monomorphic ventricular tachycardia 138/min Borderline left atrial abnormality Nonspecific ST/T changes Comment:By definition, non-sustained VT lasts less than ½ minute. It is a different species from s
QrV1 Fascicular Tachycardia
Report:Ventricular tachycardia 180/min Comment:The QRS is only 0.10â long, qualifying this as a fascicular VT. Its ventricular source is easily detected in V1, where the broad Q wave slopes obligingly over the requisite 0.06â to its nadir. The gracil
VT Slowing into AIVR
Report: Sinus rhythm Ventricular tachycardia 140/min Accelerated idioventricular rhythm 80-100/min Comment: Oddly enough, I have never seen AIVR speed up into a VT, but VT slowing into an AIVR is common enough. It is usually a relatively slow VT which
Left Bundle Branch Block-Like Ventricular Tachycardia
Report:Ventricular tachycardia 196/min[! XE !] Comment:This is a rapid VT with morphology quite similar to LBBB. The QRS duration is about 0.16â, best measured in the inferior leads. However, in V1, normally the most important diagnostic lead, it looks
VT: Dressler Beat
Report:Ventricular tachycardia 188/min Termination by ventricular fusion beat (Dressler beat) Sinus tachycardia 120/min Probable inferior infarction Comment:The rhythm strip is not taken simultaneously with the three channels above. This has the advan
Acute Infarct Pattern in Ventricular Tachycardia
Report: Ventricular tachycardia 120/min Spontaneous termination & onset in the (subsequent) rhythm strip Sinus escape beat Probable anterior infarction Comment: There is little doubt about the acute anterior infarction, despite the bizarre complexes.
R-on-P Phenomena
Report:Sinus rhythm Runs of ventricular tachycardia R-on-P âphenomenonâ Concealed retrograde conduction (top strip, end of VT) Possible ventricular fusion beat (onset of VT in bottom strip) Comment:This patient did well following intubation; no s
Fusion Beats Starting Runs of VT
Report:Sinus arrhythmia Ventricular tachycardia 132-185/min, non-sustained25 1:1 retrograde conduction Fusion beat Comment: The fusion beat starting the paroxysm of VT is diagnostic of the ventricular origin of the latter. Dressler beats are fusion
Seven Dwarfs Undetected
Report:Sinus rhythm Ventricular tachycardia (non-sustained, 7-beat run) 138-142/min 1:1 retrograde conduction Atrial escape beat Comment:The ectopic QRSs are so small that the monitor alarmed because of the low heart rate. At least it did alarm, one o
