Masquerading Bundle Branch Block
Report:Atrial fibrillation with ventricular response 80-120/min 1 Fixed-rate ventricular pacemaker rhythm 50/min 2 Fusion beat (third paced complex) 1 R-on-T pacing 1 Right bundle branch block 1 Left anterior hemiblock 1 Standard masquerading bundl
Atrial-Sensing Pacemaker Fails to Pace
Report:V1 and V3 reversed 1 Sinus rhythm 94-100/min 0.5 Ventriculophasic sinus arrhythmia 2 Atrial-sensing ventricular pacemaker 2 Complete failure to pace 1 2:1 and 3:2 AV block, Möbitz 2 2 Right bundle branch block 1 Borderline ST segment depres
Atrial Pacemaker: Failure to Sense
Report:Sinus rhythm 89/min 1 PR interval 0.20 sec 1 Atrial demand pacemaker 3 Intermittent failure to sense 4 Right bundle branch block 1 Comment:There are three atrial pacemaker beats. All three have a very early spike, always in the same spot. Th
Double Coupling
Report:Sinus rhythm 100/min 1 VEBs 1 Ventricular demand pacemaker 3 Apparent intermittent failure to sense 4 Right bundle branch block 1 Comment:The odd thing about the pacemaker’s lack of sensing is that all the paced beats occur after – and seem c
Right Ventricular Infarction: Inferior MI with RBBB
Report:Sinus rhythm 65/min Third degree AV block Junctional escape rhythm 40/min Right bundle branch block Left ventricular hypertrophy voltage R2 > 15 mm Acute inferior infarction Right ventricular infarction Comment:It is unusual for inferior in
Old and New Inferior Infarction
Report:Sinus bradycardia 44/min First degree AV block Right bundle branch block Acute inferior infarction Comment:The splayed, low-amplitude P waves are difficult to time with respect to possible 2:1 block at 88/min. Even isorhythmic AV dissociation c
Isolated Posterior Infarction
Report:Sinus rhythm 68/min Old posterior infarction Comment:There is, in V1, a dominant R wave (R/S > 1.0) with upright T wave and absence of other causes of dominant R there (RBBB, WPW âAâ, RVH). True posterior infarct. The tracing is otherwise n
Old and New Anterolateral MI with RBBB
Report:Sinus rhythm 70/min Right axis deviation (RAD) +100o Right bundle branch block Acute anterolateral + inferior infarction Comment:Three years previously, the patient was in CCU with known old anterolateral MI and chronic RBBB (Fig 79a). He was t
Old Anteroseptal MI & BBBB
Report:Atrial fibrillation with rapid response 160/mi9n Right bundle branch block Left anterior hemiblock Standard masquerading bundle branch block Old anteroseptal infarction Comment:In 1 and aVL the QRS resembles LBBB rather than RBBB, a situation
Acute Cor Pulmonale
Report: Supraventricular tachycardia, probably sinus, 160/min Right axis deviation +95o Small voltage Right bundle branch block Borderline T wave changes Comment: The rhythm strip from a later trace is superimposed over the original one to show the p
