Sinus Bradycardia: Escape-Capture Bigeminy
Report:Sinus bradycardia 34 - 43/min Junctional escape beats Escape-capture bigeminy Phasic aberrant conduction, RBBB type Comment: The mechanism of the bigeminy is sinus bradycardia. Here the effective sinus cycle is the same as the actual one; in ot
Advanced Second Degree AV Block
Report:Sinus tachycardia 100/min Second degree AV block, advanced ST/T changes consistent with MI/ischæmia Comment:The conducted P waves are all associated with slightly variable first degree block and the QRS complex is narrow: the site of the block
Atropine Bradycardia
Report: Top: Sinus rhythm 83 - 85/min Second degree AV block Escape-capture bigeminy Ventricular rate 55/min Bottom: Sinus tachycardia 100/min 2:1 AV block Ventricular rate 50/min Comment: In the top strip, a basic 2:1 AV block is modified by th
First Degree AV Block
Report:Sinus rhythm 72/min First degree AV block (PR 0.42â) VEBs SVEBs, blocked Left axis deviation â60o Old inferior and anterior infarction Junctional escape beats (last and first) QRS complex Comment:There is some variation in the long PR in
Sinus Pauses
Report: Sinus rhythm Sinus pauses, probably sinus arrests Atrial escape beats Comment: The first beat in each group has a different-contoured P wave and is probably an atrial escape beat. This prevents the pause being measured, but it is already more t
Classical Wenckebach
Report:Sinus rhythm 82 â 86/min Second degree AV block, Möbitz 1 Left atrial abnormality (LAA) Recent inferior infarction Comment:Most clinically observed Wenckebach periods are in some way atypical; the long ones are so as a rule. The commonest at
Echo Beats
Report: Sinus rhythm (7 beats) Ventricular tachycardia (4-beat run) VEBs, couplet (two beats) Reentry (echo) beats of ventricular origin (two beats) Comment: There are more QRS complexes of ventricular than supraventricular origin here - 8 vs. 7. Both
Let the Sleeping Dog Lie?
Report:Sinus arrhythmia 45 - 68/min Second degree AV block Two blocked P waves Comment:It is disconcerting to see a spontaneous 3.7" pause, but (i) the patient had a recent inferior MI and (ii) remained asymptomatic during similar episodes while awake.
First Degree AV Block
Report:Sinus rhythm 60/min First degree AV block PR interval 0.62â Indeterminate axis Absolute small voltage Minor T wave changes Comment:The PR interval is considerably longer than the R-P interval, confusing the computer into diagnosing junction
Atrial Fusion Beats
Report:Sinus arrhythmia 64 â 80/min Junctional rhythm 58/min Atrial fusion beats Nonspecific ST/T changes Comment:Three P waves in the middle of the tracing are clearly intermediate in shape between sinus P waves and the junctional retrograde ones;
