Interpolation in Alternate Cycles
Report:Sinus rhythm 51/min VEBs, interpolated in alternate cycles Trigeminy Non-specific ST/T changes Comment:The VEBs are typical, with nonsense axis and qR morphology in V1; their concealed retrograde conduction114, prolonging the PR intervals of th
Fascicular VT with 1:1 Retrograde Conduction
Report:Ventricular tachycardia 106/min 1:1 retrograde conduction Comment:This is a very slow VT â well within what some authorities would call AIVR. It is fascicular, with the QRS complex only 0.12â long. Its morphology is that of basic RBBB/LAHB, o
VEBs: Trigeminy & Trigeminy
Report:Sinus arrhythmia Left atrial abnormality (LAA) First degree AV block Atrial ectopic beat (second P wave in the bottom strip) VEBs in trigeminy Concealed retrograde conduction Comment:In the top strip, every third P wave is blocked by a VEB. I
Interpolated VEBs & Couplets
Report:Sinus rhythm VEBs, some interpolated, some (bottom strip) in couplets (pairs) Comment:In the top strip, the first VEB blocks the ensuing sinus P wave, creating a fully compensatory pause. The other two penetrate the AV junction retrogradely (conc
Semiventricular Tachycardia
Report: Sinus tachycardia 100/min VEBs in bigeminy Possible ventricular fusion Left axis deviation (LAD) â 40o LVH with ST/T changes Inferior infarction, probably old Comment: Semiventricular is one of my own neologisms. Foreigners often take grea
Trigeminal Tachycardia: Alternate Cycle Interpolation
Report: Sinus rhythm 85/min VEBs, interpolated in alternate cycles Trigeminy Comment: The P waves are regular throughout, but the PR intervals alternate, due to interpolation of the VEBs. The LBBB pattern of the VEBs has a characteristically slurred do
