It's the ECG's that george rejects that makes George's ECG's the best.
Complete AV Block in Shock
Report:Atrial flutter 375/min Complete (3rd degree) AV block Junctional rhythm 65/min Right axis deviation +90o ?LPHB Right bundle branch block Acute inferior and anteroseptal infarction Leads V3-6 probably right-sided: right ventricular infarction
LBBB: Old Myocardial Infarction
Report:Sinus rhythm 64/min Third degree AV block Junctional escape rhythm 36/min Left bundle branch block QRS 0.22” Probable old anterior infarction Comment:The patient had LBBB since his original infarction; the present morphology is identical to
Incongruous BBBB
Report: Sinus rhythm 84 – 88/min Advanced second degree AV block 3:1 & 4:1 AV block Right bundle branch block PR interval 0.32” Left bundle branch block PR interval 0.20” Comment: This is quite rare. The two bundle branch blocks have different but
Alternating RBBB & LBBB?
Report: Sinus rhythm Second degree 2:1 AV block Alternating RBBB & LBBB Discordant PR intervals Left axis deviation -35o (in RBBB) Non-specific ST/T changes (during RBBB) Or: Conducted RBBB with 2:1 and advanced 2o AVB Ventricular escape beats Es
An Optical Illusion
Report: Sinus tachycardia 116/min First degree AV block PR 0.40” Normal axis Left bundle branch block QRS 0.125” Comment: This is one of the traces I originally misreported (as NPJT). One way for any ECG to find its way into this Library is to have
1o AV Block Expressing BBBB
Report: Sinus rhythm 77 – 82/min Left atrial abnormality (LAA) First degree AV block PR 0.22” Intermittent right bundle branch block + left anterior hemiblock PR 0.16” Nonspecific T wave changes Comment: At first, one would postulate a dissociated
LBBB with RAD: Acute Inferior Infarction
Report:Sinus rhythm 96-100/min Third degree AV block Junctional escape rhythm 45/min Left bundle branch block Right axis deviation +95o Acute inferior infarction Comment:Three contributors to heart failure are present in this trace: Acute infarction
AV Block: Nodal or Ventricular?
Report:Sinus rhythm Second degree AV block Intermittent right bundle branch block & left posterior hemiblock Prolonged QT interval Comment:The PR interval lengthens between the first and the second beat, but fails to grow observably longer between the
Bradycardia-Dependent RBBB
Report: Sinus/atrial rhythm Shifting pacemaker First degree AV block Second degree AV block, Möbitz I Blocked SVEBs, ?reentry of atrial origin Bradycardia-dependent right bundle branch block Comment: This is the same patient as in Case 1. All the l
Conducted LPHB and Escaping LAHB
Report:Sinus rhythm 82/min Left atrial abnormality (LAA) 2:1 AV block Right bundle branch block Left posterior hemiblock Junctional escape (first two) beats RBBB + LAHB morphology Nonspecific ST/T changes Comment:Most commonly, the escape rhythm h
