AV Pacemaker: No Ventricular Lead
Report:Atrial pacemaker rhythm 59/min 2 Right bundle branch block 2 AV interval 0.31” ?no ventricular lead 4 Q waves in 1, aVL, V5-6 – possible old anterolateral infarction 2 Comment:The diagnosis is suggested by the unusually long AV interval, althou
Fat QRS Complexes
Report: Sinus rhythm 1 First degree AV block (PR 0.24”) 1 Right bundle branch block (QRS 0.20”) 2 VEBs ? junctional premature beats (QRS 0.20”, one narrower 0.12”) 1 Demand pacemaker 2 LBBB morphology (QRS 0.20”) 0 Fusion beats (narrowest QRS 0.16”,
Emphysema: Left Axis Deviation
Report:Sinus tachycardia Right atrial abnormality Left axis deviation â40o Possible old anterior infarction Suggestive of emphysema Comment:Characteristically, S2 > S3 in LAD due to emphysema vis à vis LAHB. Some argue this is not a true LAD but a
Slurred R Ascent in V1: Exception to the Rule
Report:Ventricular tachycardia 168/min Comment:The contour of V1 suggests a rabbit in profile, with overlapping ears â not very helpful. If one, more properly, imagines looking at the rabbit from behind, there is a suggestion of larger right ear â no
Irregular Monomorphic Ventricular Tachycardia
Report:Ventricular tachycardia 128-170/min.[! !][! XE "Ventricular tachycardia:uniform" \t "See monomorphic" !] Periods of bigeminy Comment:It is uncommon for monomorphic VT to be irregular. The irregularity, however, is confined to long-short cycle alt
Alternate Cycle Antecedent P Waves
Report:Ventricular tachycardia 125/min Probable 2:1 retrograde conduction Comment:The diagnosis of VT is supported by the QRS duration of 0.18â, the indeterminate abnormal axis and the left rabbit ear in V1 being taller than the right. The relativel
SVT with Pre-Existing Left Bundle Branch Block
Report:Supraventricular tachycardia 200/min[! XE "Supraventricular tachycardia:LBBB:QRS0.16\"" !] Northwest axis +230o Small voltage in frontal leads Left bundle branch block Comment:This is a difficult trace to diagnose with certainty: the main featu
Ventricular Tachycardia: Pseudo P Waves at Either Complex End
Report:Sinus rhythm 84/min. Ventricular tachycardia 132/min. Complete AV dissociation. Comment:The broad-complex tachycardia has QRS duration 0.20", extreme "Northwest" axis and, best of all, taller left rabbit ear in V1 to declare its ventricular orig
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,
