Ventriculophasic Sinus Arrhythmia
Report:Sinus rhythm. Second degree AV block, Möbitz 1 Ventriculophasic sinus arrhythmia. Phasic aberrant conduction Comment:The âshortâ complexes are aberrantly conducted sinus beats. The promotion from 2:1 to 3:2 block has produced a long-short
Carotid Sinus Massage: 2o AV Block
Report: Sinus rhythm ?Accelerated conduction (PR interval 0.11â) Second degree AV block Comment: The massage was performed in the hope of unmasking WPW conduction, of which there is a soupçon in the initial slurring of the QRS. Instead of broadening
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
Unusual Wenckebach Sequences
Report:Sinus arrhythmia Second degree AV block, Möbitz 1 Bradycardia-dependent LBBB (4th beat in the top strip) ? Respiratory artefact ? Bradycardia-dependent incomplete LBBB ? Junctional escape beats with non-phasic aberrant conduction Comment:T
Verapamil Wenckebach
Report: Sinus rhythm Möbitz 1 (Wenckebach) second degree AV block Comment: This is a very low-grade block and the patient is monitored anyway. Nothing needs be done immediately. In the long term, an antihypertensive without AV blocking properties shoul
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
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
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
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
