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

Report:Sinus rhythm 84/min Borderline left atrial abnormality (LAA) Second degree AV block, unspecified Junctional escape beats Escape-capture bigeminy LVH with ST/T changes Comment:Only every third sinus P wave is conducted, with a PR interval just
Ventricular Standstill in Sinus Tachycardia
Report:Sinus tachycardia 113/min Second degree, mostly 2:1 AV block Complete AV block â ventricular standstill Intraventricular conduction delay (known LBBB) Comment:This is almost certainly Möbitz 2 AV block in view of the associated bundle branch
Slow Junctional Escape in Complete AV Block
