Pacemaker Confusion in Pseudofusion: Transposition of Great Vessels
Report: Sinus tachycardia 110/min 1 Left atrial abnormality (LAA) 1 Indeterminate abnormal axis ±194o 2 Right ventricular hypertrophy 3 Pacemaker sensing spikes (pseudofusion beats) 3 Comment: The spikes occur after the onset of the QRS complex, pr
Emphysema: Northwest Axis
Report: Sinus tachycardia 130/min Right atrial abnormality P axis +85o Indeterminate abnormal axis +250o S1S2S3 pattern Poor R wave progression RSRâ in V1-2 Comment: The patient had advanced emphysema, with dilated right ventricle and clinical c
S1S2S3 Pattern
Report: Sinus rhythm Borderline biatrial abnormality Indeterminate axis 200o S1S2S3 pattern RSRâ V1 Comment: The diagnosis of S1S2S3 pattern requires, strictly speaking, S wave larger than the corresponding R wave in the three standard leads, as in
Left Axis Deviation: Axis Illusion of Emphysema
Report:Sinus rhythm 92/min Left axis deviation â80o Right atrial abnormality (RAA) Q waves in 3, aVF Comment:Although it is not an abnormality per se, the QRS complexes in emphysema are often characteristically slender. The P waves are pointed and
3:2 Möbitz 2 AV Block
Report: Sinus tachycardia 106/min Left atrial abnormality (LAA) Möbitz 2 second degree AV block, 3:2 conduction, with bigeminy Indeterminate axis â140o Right bundle branch block Anteroseptal infarction, probably old Comment: In all instances of t
First Degree AV Block
Report:Sinus rhythm 60/min First degree AV block PR interval 0.62â Indeterminate axis Absolute small voltage Minor T wave changes Comment:The PR interval is considerably longer than the R-P interval, confusing the computer into diagnosing junction
