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
Atrial Fusion Beats
Report:Sinus rhythm Junctional ? atrial rhythm Shifting (atrial) pacemaker Atrial fusion beats AV dissociation Probable third degree AV block Pacemaker rhythm 63/min Comment:Again, this is a "trick" question, designed to make one look (in vain) for
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
Congenital Complete Heart Block: Ventriculophasic Sinus Arrhythmia
Report:Sinus rhythm 67 â 70/min Third degree AV block Junctional escape rhythm 42/min Ventriculophasic sinus arrhythmia Right atrial abnormality (RAA) Comment:The ventricular rate is regular and slow, the faster P waves completely dissociated: comp
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
Rabbit Ears For and Against
Report:Upper strip: Sinus tachycardia 104/min VEBs, late-diastolic (R-on-P âphenomenonâ) Lower strip: Sinus rhythm SVEBs, probably of atrial origin RBBB aberrancy Couplet, second SVEB non-conducted Comment:Looking at the rabbit from behind, if
Fusion Terminating AIVR
Report: Sinus rhythm 74 â 80/min Accelerated idioventricular rhythm 69 â 74/min Ventricular fusion beat Comment: The AIVR accelerates, but to no avail: the faster sinus rhythm takes over by the middle of the recording. Between the two is a typical
VEB couplets: Two for the Price of One
Report: Sinus rhythm 78/min VEBs, frequent, some in couplets (pairs) Poor R wave progression Nonspecific ST/T changes Comment: The VEBs have typical qRRâ morphology, with left rabbit ear taller than the right; the pauses are fully compensatory. The
