Reversed Atrial & Ventricular Electrodes
Report: Sinus rhythm (non-conducted) 1 Pacemaker rhythm 78/min 1 Reversed A & V leads 5 Intermittent atrial captures with 1o AV block & IVCD (unspecified) 3 Comment: This was a prank by a junior colleague, in this case harmless, but interesting. The v
Junctional Extrasystoles with RBBB Conduction
Report:Sinus rhythm 81/min 1 Atrial-sensing ventricular pacemaker 3 AV interval 0.10 sec 1 Junctional premature beats with RBBB conduction 4 ST/T changes consistent with ischæmia 1 Comment:Like in the previous case, there are large ventricle-pacing s
Hypothermia Without Bradycardia
Report: Sinus rhythm 76/min Left axis deviation â 35o Intraventricular conduction delay (IVCD) QRS 0.14â) J (Osborn) waves (hypothermic humps) Nonspecific ST/T changes Prolonged QT interval QTc 0.50â Comment: The core temperature was 31oC. T
Surprising Face of Capnocytophaga canimorsus Septicaemia
Report:Sinus rhythm 90/min Acute anterolateral infarction Comment:The patient had a clinically obvious septic shock. The organism was Capnocytophaga canimorsus, a rare cause of systemic sepsis (dogsâ teeth being cleaner than human) distinguished by it
Tombstones
Report:Sinus tachycardia 111/min Acute extensive anterior infarction Comment:The ST segment hyperelevtion (âtombstoningâ) bodes ill for the patient. This one died within 24 hours, ventilated for cardiogenic shock and resultant multi-organ failure. A
Negative T & U Waves
Report:Sinus rhythm 78/min Diffuse nonspecific ST/T changes Prominent U waves ?hypokalæmia Comment:U wave polarity follows that of the preceding T wave, except in ischæmia, where isolated U negativity may be a marker of critical LAD artery lesions. I
Stage of Illusion
Report:Sinus rhythm 63/min Normal trace Comment:This is a potentially dangerous situation: acute infarct pattern normalises in that ST segments are again isoelectric and the T wave have not yet turned. Below (Fig 54a) is the trace taken 3 hours previous
Parkinsonâs Disease
Report: Sinus rhythm 80/min SVEB Borderline (-30o) left axis deviation Somatic 5/sec tremor consistent with Parkinsonâs disease Comment: Atrial flutter has the same rate â 300/min â as the extrapyramidal tremor of parkinsonism. In this trace, le
Acute Coronary Syndrome
Report:Sinus rhythm 97/min ST segment depression c/w infarction/ischaemia Comment:The distribution of ST segment shifts is similar, but less pronounced, than in Case 2: diffuse ST depression with elevation confined to aVR and V1, greater in aVR. This ma
Small Ts in 1 and V6
Re-arrange ECGs to true time sequence, re-write report! Report:Sinus rhythm 59/min T wave changes c/w ischæmia Comment:The TV1 > TV646 or T3 > T1 phenomenon is less well known than it should be. It is not normal, as most computer programmes would have
