The Commonest Cause of a Pause
Report:Sinus tachycardia 100/min 1 Atrial-sensing ventricular pacemaker rhythm 1 Blocked SVEB 6 Left atrial abnormality (LAA) 1 Right bundle branch block 1 Comment:There is a subtle but definite change in the T wave of the last paced beat before the
Symptomatic Bigeminy Due to Trigeminy
Report: Sinus rhythm 80/min 1 Blocked SVEBs, trigeminal 8 A-sensing ventricular pacing throughout 1 Comment: Not surprisingly, the pacemaker was blamed. It was programmed to pace at 60/min, with a sleep mode of 50/min during night hours. There was no
Unusual Mechanism of Escape-Capture Bigeminy
Report: Sinus rhythm 0.5 SVEBs, blocked, in (atrial) trigeminy 2 AV sequential pacemaker, atrial-sensing (probably DDD) 0.5 Failure to sense SVEBs 4 Atrial-paced escape beats 0.5 Ventricular bigeminy (atrial trigeminy!) 2 Nonspecific T wave changes
Atrial Pacemaker: Failure to Sense
Report:Sinus rhythm 80/min 1 Atrial pacemaker 2 Failure to sense 2 Blocked atrial P waves of pacemaker origin 4 Left bundle branch block 1 Comment:There is a profusion of pacemaker spikes and LBBB complexes, giving an initial impression of variable a
Triple Hæmodynamic Handicap
Report:Upper strip: Dual pacemaker rhythm 89/min 1 Ventricular pacing, no atrial capture 1 1:1 retrograde (ventriculo-atrial) conduction 1 SVEB, blocked 3 Atrial capture by the atrial lead following the SVEB 1 Lower strip: Dual pacemaker rhythm 89
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
Right Ventricular Infarction or Prinzmetal Angina?
Report:Sinus rhythm 78/min SVEBs, one aberrant, two blocked Wenckebach phenomenon Acute inferior infarction Right ventricular infarction Left ventricular hypertrophy with ST/T changes Comment:The diagnosis of Prinzmetal angina was suggested when ser
Anterior Infarction and Rate-Dependent LBBB
Report:Sinus rhythm 66/min SVEBs, blocked Rate-dependent left bundle branch block Anterior infarction ?age Comment:The pauses created by the non-conducted SVEBs are long, but still not fully compensatory. The complexes terminating the pauses are norma
VEB Revealing Old Infarction
Report:Sinus rhythm Atrial bigeminy VEB LVH with ST/T changes Old anterior infarction Comment:A VEB can at times show infarctional Q waves not visible in normal complexes. This holds for QR and similar morphologies, but not the QS complexes44. In thi
RBBB with Right and Left Axis
Report:Sinus rhythm SVEBs, bigeminal Left axis deviation in sinus beats, probably LAHB Right axis deviation in SVEBs due to LPHB Right bundle branch block throughout Borderline T wave changes Comment:With RBBB the frontal axis is determined by the i
