VEBs in Bigeminy
Report: Sinus rhythm 67 – 71/min 1 Ventricular pacemaker 1 VVI mode 4 Ventricular fusion beats 2 VEBs 1 Bigeminal 0.5 Uniform 0.5 Comment: The interesting question is whether the atrial deflections following VEBs are blocked sinus P waves or retrog
Beginning of an Endless Loop
Report: Sinus rhythm 79/min 1 VEB 1 Ventricular escape beat, preceded by attempt at atrial pacemaker escape 1 VEBs, dimorphic couplet 1 Retrograde conduction 2 Retrograde P sensing and generating pacemaker tachycardia 103/min 4 Comment: The retrogra
Atrial Sensing and Pacing
Report:Sinus rhythm 75/min 1 VEB 1 Atrial-sensing ventricular pacemaker 3 Atrial sensing and pacing ventricular pacemaker (last beat) 4 Left atrial abnormality (LAA) 1 Comment:This is a DDD pacemaker, responding to both the atrial activity and the la
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
Ignored VEBs in Trigeminy
Report:Sinus rhythm 1 VEBs, trigeminal 3 Atrial-sensing, ventricular-pacing electronic pacemaker 7 Comment: This case is similar to No. 86, where the pacemaker leads cannot “recognise” the slowly rising ectopic R wave. Here, however, it follows the P
Holter Monitor: Endless Loop Tachycardia
Report:AV sequential pacemaker rhythm 75/min 1 SVEB, blocked, inhibiting atrial pacemaker 2 Ventricular pacemaker rhythm with 1:1 retrograde conduction 2 Endless loop tachycardia 120/min 3 VEB terminating the endless loop tachycardia 1 AV sequential
Inferior MI: Reciprocal Changes & Remote Ischæmia
Report:Sinus rhythm 71/min Acute inferior infarction Comment:The reciprocal changes, although minuscule in 1 and very modest in aVL, are spread through all the chest leads. This is now thought to reflect a large infarction rather than separate, remote i
ST Elevation or Non-Q Infarction?
Report:Sinus rhythm 87/min ST/T changes c/w infarction/ischæmia Comment:This type of tracing is difficult to define. ST segment elevation infarction requires, by definition10, 1 mm elevation in at least two contiguous leads sustained over 30 minutes. H
Acute Anterolateral Infarction
Report:Sinus rhythm 68/min VEBs Acute anterolateral infarction Left ventricular hypertrophy voltage Comment:The left circumflex artery was 100% blocked, but successfully dilated and stented at the PTCA. However, a sizeable posterolateral infarction re
Fascicular VT in Anterior Infarction
Report:Ventricular (fascicular) tachycardia 103/min RBBB/LAHB morphology Acute anterior infarction Comment:It is possible that the tachycardia is junctional, with aberrancy, except that lead 1 does not look right for RBBB, with or without LAHB; also, i
