Two Pacemakers, One Pacing
Report:Sinus rhythm 1 Third degree AV block 1 Ventricular pacemaker rhythm 62/min 4 Failed dual pacemaker 59/min 4 Comment: The two pacemakers and the sinus rhythm are completely dissociated from each other. There is no atrial or ventricular capture
LBBB: Old Myocardial Infarction
Report:Sinus rhythm 64/min Third degree AV block Junctional escape rhythm 36/min Left bundle branch block QRS 0.22â Probable old anterior infarction Comment:The patient had LBBB since his original infarction; the present morphology is identical t
LBBB with RAD: Acute Inferior Infarction
Report:Sinus rhythm 96-100/min Third degree AV block Junctional escape rhythm 45/min Left bundle branch block Right axis deviation +95o Acute inferior infarction Comment:Three contributors to heart failure are present in this trace: Acute infarction
Invisible LAHB Causing 2:1 AV Block
Report:Sinus tachycardia 120/min 2:1 AV block Right axis deviation +140o Right bundle branch block Possible old anterolateral infarction Comment:The cause of the RAD may be RVH or old anterolateral MI but the former was certainly not present clinical
Congenital Heart Block with Long QT Interval
Report: Sinus rhythm 100 - 110/min Third degree AV block Junctional escape rhythm 48/min VEB SVEB Prolonged QT interval 0.60â QTc 0.53â Comment: This case has been reported73. While it is not possible to exclude post-syncopal QT prolongation i
Spurious ST Segment Elevation
Report: Sinus bradycardia 43/min Left atrial abnormality First degree AV block Escape-capture bigeminy Third degree AV block (mid-second strip onward) Junctional rhythm 64/min Comment: The broad shallow sinus P waves, with their first degree AV bl
Scary Pauses in Congenital AV Block
Report:Sinus arrhythmia Third degree AV block Junctional escape rhythm 5.52" pause Comment:Most patients with (idiopathic) congenital heart block have a reasonably fast junctional pacemaker and can get by without pacing. Presence of prolonged pauses m
Complete AV Block
Report:Third degree AV block Sinus bradycardia 42/min Junctional beats (top strip) Atrial fibrillation Junctional escape rhythm 36/min Pacemaker rhythm 82/min Short QT interval ? digoxin toxicity Comment:The varied atrial activity has no effect on
Failed Pacemaker?
Report: Sinus tachycardia 104 - 124/min First degree AV block[!xe "PR interval:long" \t "See AV block, first degree"!] Second degree AV block, probably Möbitz 2 Third degree AV block Ventricular standstill Junctional escape rhythm, ventricular escap
Aberrant Reentry Beats of Junctional Origin
Report: Sinus bradycardia 36/min (middle & end of bottom strip) Sinus arrest, possibly exit block Junctional escape rhythm Reentry (echo) beats of junctional origin Retrograde first degree VA block 0.26â Antegrade first degree AV block 0.26â Lef
