It's the ECG's that george rejects that makes George's ECG's the best.
Sino-Atrial Exit Block
Report:Sinus rhythm 52 – 54/min Sino-atrial exit block Bigeminy Nonspecific T wave changes Comment:There are two long cycles. One is slightly longer, the other slightly shorter than twice the preceding P-P cycle. Allowing for some sinus arrhythmia
Sino-Atrial Exit Block
Report:Sinus rhythm 74/min 3:2 sino-atrial exit block Bigeminy Negative U waves in lead 1 Comment:The same comments can be made here as for the preceding Case 93. It, too, could have Möbitz 2 mechanism. Below (Fig 94a) is another trace, with long c
Bidirectional Ventricular Tachycardia
Report: Bidirectional ventricular tachycardia Probable digoxin toxicity Supraventricular rhythm of uncertain origin ? atrial fibrillation VEB Multiform ventricular tachycardia Comment: Despite the adverse prognosis and her age, she was discharged hom
Bigeminal Ventricular Tachycardia
Report: Monomorphic ventricular tachycardia 90 – 110/min Alternating cycle length, with bigeminy Retrograde conduction, 1:1 Probable old anterior infarction Comment: Most of the rate variation is in the long cycles. The basic mechanism is probably 3:
R-on-T Ventricular Fibrillation
Report: Sinus tachycardia Second degree AV block VEBs Bigeminy R-on-T phenomenon Ventricular fibrillation ST segment elevation consistent with epicardial injury Comment: The VEB with the shortest coupling interval initiates VF. It comes right on to
Bigeminal Ménage à Trois
Report: Sinus tachycardia 105/min Intraventricular conduction delay QRS 0.12” VEBs, couplets Bigeminy Ventricular fusion beats Comment: The conducted sinus beats, with the VEBs, come in three varieties: “pure” sinus or “pure” ectopic beats, and fu
VEBs: (Con)fusion Bigeminy
Report: Sinus rhythm VEBs, late-diastolic, in bigeminy Ventricular fusion beats Comment: There are, depending on the VEBs’ timing, different degrees of fusion. Note how the sinus contribution is proportional to the PR interval of the fusion beat: the
Bizarre Trigeminy
Report:Atrial fibrillation Advanced or complete AV block Ventricular (first triplet) and junctional escape beats VEBs in couplets Trigeminy Small voltage, frontal leads Vertical heart position Possible old anteroseptal infarction Comment:There is
Parasystole[!xe "Parasystole" \t "See Ventricular parasystole"!]
Report: Sinus rhythm Ventricular parasystole 41 - 43/min Comment: The diagnostic feature, unrecognised by the xylocaine pushers, is the variable coupling interval and the fixed interectopic one. And the fusion beat. Parasystole is, generally, resistant
QRs VEBs in V1
Report: Sinus rhythm VEBs, late-diastolic, in bigeminy Comment: The VEBs have an Rs morphology; the Q wave is in fact a superimposed, dissociated sinus P wave. The dissociation is incomplete in the case of the 6th and the 10th complex, where ‘a tad of f
