A Far-Reaching Interpolation
Report:Sinus rhythm. VEBs, frequent, two interpolated. Comment:The concealed retrograde conduction governing the PR interval after an intercalated VEB rarely affects more than one cycle. In the top and middle strips, the first VEB is intercalated and
Möbitz 2 Block
Report: Sinus rhythm Second degree AV block, Möbitz 2 Right bundle branch block Comment: The conducted P waves show no increment in their PR intervals prior to the blocked one - a clear-cut case of Möbitz 2 block. Typically, the QRS itself is prolong
Joggerâs Wenckebach
Report:Sinus rhythm Wenckebach (Möbitz 1) second degree AV block, atypical Periods of 2:1 conduction (block) Comment:The patient may well have a mild form congenital heart block, but the progressive angina should call for evaluation of his coronary re
Sinoatrial Block: CVA
Report:Sinus rhythm Sinus pauses - probable Wenckebach exit block Junctional escape beats and rhythm Atrial fusion beats SVEB. Comment:The sinus cycles tend to shorten before the pause, a characteristic of Möbitz 1 (Wenckebach) exit block. There is
Three Causes of Pauses & Many Diagnoses
Report:Sinus rhythm 88 - 92/min Left atrial abnormality (LAA) P wave 0.12â SVEB, non-conducted VEBs, late-diastolic Ventricular fusion beat (third last complex in the bottom strip) Junctional escape (top strip) and premature beat (bottom strip), R
Quinidine Cardioversion
Report: Atrial flutter with variable block Spontaneous termination Sinus rhythm Sinus bradycardia (top strip) Sinus pauses (middle strip) Normal sinus rhythm (bottom strip) Left atrial abnormality (LAA) Right bundle branch block Comment:The sympto
The Race Is Not to the Swiftâ¦
Report: Sinus rhythm & arrhythmia 58 - 74/min. Left anterior hemiblock (LAHB). Right bundle branch block (RBBB). Second degree AV block, 2:1, rate-dependent. Comment:The patient has, in addition to obvious conduction problems, an abnormally marked s
Concealed and Manifest Retrograde Conduction
Report:Sinus rhythm VEBs, one interpolated Reentry (echo) beat of ventricular origin Borderline left atrial abnormality (LAA) Comment:The ectopic beats are just about 0.14â long, with QR morphology in V1 and monophasic R in standard lead 1. Both, at
Pacemaker-Sinus Escape-Capture Bigeminy
Report: Sinus rhythm Second degree AV block, unspecified Intraventricular conduction delay (QRS 0.12") Pacemaker escape beats Escape-capture bigeminy Comment: The conducted sinus beats have normal PR intervals, but the P waves following them have the
Ventriculophasic Sinus Arrhythmia
Report: Sinus rhythm Ventriculophasic sinus arrhythmia[!xe "Ventriculophasic sinus arrhythmia" \b!] 2:1 Second degree AV block Non-specific T wave changes[!xe "P wave:mime by U wave" \b!] Comment: This trace shows that the ventriculophasic effect can
