Flutter Bigeminy
Report:Atrial flutter 252/min 2 Alternating 2:1 & 4:1 block 2 Demand pacemaker 1 Pseudofusion spikes in alternate complexes 2 Small voltage, limb leads 1 Possible old anteroseptal infarction 1 Nonspecific ST/T changes 1 Comment:The pacemaker rate i
Flutter with Failed Pacemaker
Report:Atrial flutter 250/min 2 4:1 block 1 Failed pacemaker 3 Poor R wave progression 1 Nonspecific ST/T changes 1 Comment:The intrinsic pacemaker rate is 70/min – the distance from the tip of the sensed R wave to the first pacing spike and also the
Flutter with Paced Tachycardia
Report:Atrial flutter 250/min 4 Electronic pacemaker, atrial-sensing 5 Ventricular rate approximately 120-130/min 1 Comment:The flutter can be made out as the underlying rhythm during pacing in the two longer ventricular cycles: there is an obvious neg
Left Ventricular Pacemaker
Report:Atrial flutter 320/min 2 Probable third degree AV block 3 Ventricular pacemaker rhythm 80/min 2 Left ventricular lead 3 Comment:By coincidence, the F wave rate is almost exactly four times the paced QRS rate and the impression is strong of flut
Inferior Infarction: Blocks and Arrhythmias
Report:Sinus tachycardia 122/min Second degree AV block, unspecified Junctional escape beats and rhythm 46/min Non-phasic aberrant conduction Acute inferior infarction Comment:It is said that the presence of 2o AV block in inferior infarction denotes
Adenosine-Induced Autogain102
Report: Atrial flutter 320/min with 2:1 block Ventricular standstill (third strip) Continued atrial flutter Escape complexes of unknown origin Resumed 2:1 conduction of flutter (last two strips) Comment: At first the recording looks like the rare but
Pædiatric Right Ventricular Hypertrophy
Report:Probable flutter 300/min with 2:1 block Right axis deviation Right ventricular hypertrophy Comment:In children with congenital heart disease the abnormal RAD is usually manifest as S1S2S3 morphology. The qR in V1 indicates that it is a true RAD,
Adenosine Asystole
Report:Atrial flutter 300/min High-grade (advanced) second degree AV block Transient asystole Ventricular escape beat Comment:The patient was admitted to CCU in flutter 310/min with 2:1 block (Fig 12a below). In all fairness, distinction from SVT cann
Bigeminy and Trigeminy: Atrial Flutter
Report:Atrial flutter 250/min Alternating 4:1 & 2:1 (2:1 + 3:2) conduction, with bigeminy (top) 2:1 + 4:3 conduction, with trigeminy (bottom) Comment:Typical flutter has a basic 2:1 block and a more distal, Wenckebach block; this combination accounts f
Concealed Conduction: Atrial Flutter
Report:Sinus rhythm Left atrial abnormality (LAA) Second degree 2:1 AV block Atrial flutter 300/min Third degree AV block Idioventricular escape rhythm 41/min Inferoposterolateral MI, age uncertain, probably old Comment:The flutter maintains a stat
