Single Failure to Capture
Report:Sinus rhythm 63/min 2 Complete AV dissociation 4 Pacemaker rhythm 80/min 2 Single failure to pace 4 Comment:AV block cannot be accurately diagnosed here: the atrial (sinus) rate is too slow and the ventricular (pacemaker) rate too fast. Just be
Positive Concordant Precordial Pattern
Report:Pacemaker rhythm 63/min 2 1:1 retrograde conduction 3 Positive concordant precordial pattern 5 Comment:This is a temporary, bipolar unit, inserted in CCU. The patient had a very large right ventricle or the lead is inadvertently placed in the po
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
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
LBBB: Negative Concordant Precordial Pattern
Report: Sinus rhythm PR interval 0.20â Left atrial abnormality Normal axis Left bundle branch block Comment: History of infarction and marked cardiomegaly are clues as to why there is a concordant precordial QS pattern. This example has normal axis
Pædiatric Wolff-Parkinson-White Conduction
Report:Sinus rhythm 190/min Wolff-Parkinson-White conduction, type âAâ Comment:At the age of one to two months, the rate below 191/min is not reported as tachycardia. Atrial activity is barely visible but, where seen, remains consistent with sinus r
Empty Wenckebach Pauses
Report: Sinus rhythm SVEB (second QRS, bottom strip) Second degree AV block, Möbitz 1 Junctional beats, non-conducted ?Reentry beats of sinus origin Atrial fusion beats, non-conducted Comment: In the upper strips, the Wenckebach sequences are termi
Unfinished Wenckebach
Report:Sinus rhythm 76/min Wenckebach phenomenon Atrial trigeminy, possible reentry beats of sinus origin, blocked Frequent VEBs, uniform Positive concordant precordial pattern Left atrial abnormality (LAA) Left anterior hemiblock (frontal axis â6
