Neostigmine Toxicity
Report:Sinus rhythm 3:2 sino-atrial exit block Nonspecific T wave changes Comment:The patient was paralysed by vecuronium for a CAT scan after a traffic accident; she was brought back to Casualty and the relaxant was reversed with 5 mg neostigmine and
LVH â Volume Overload Pattern
Report:Sinus rhythm 65/min Left atrial abnormality Left ventricular hypertrophy, volume overload pattern RSRâ in V1-2 Comment:The LAA is best seen in V3-5, along with prominent T waves. With LVH voltage in the chest leads this constitutes evidence f
Sotalol Overdose
Report:Sinus rhythm 62/min 2:1 AV block Ventriculophasic sinus arrhythmia Prolonged QT interval 0.58â QTc 0.58â Comment:The blocked alternate P waves are not very obvious, superimposed on prolonged, themselves rather wavy, T waves. Also, alternat
Hypokalæmia: Helmet-Like TU Waves
Report:Sinus rhythm 96/min TU waves c/c hypokalæmia Comment:The appearance of rounded TU waves in the inferior leads is very characteristic, often leading to a spot diagnosis. This ECG is made easier by the helpful separation of T and U waves in the pr
Pericarditis
Report:Sinus rhythm 67/min First degree AV block PR interval 0.22â ST segment elevation c/c pericarditis Comment:The features favouring pericarditis are ST elevation in both the frontal and the precordial leads, involvement of V6 and normal QRS and
Fatal Pulmonary Embolism
Report:Sinus tachycardia 102/min ST/T changes c/c infarction/ischæmia Possible acute cor pulmonale S1T3 pattern Comment:This is a difficult tracing. The modest ST elevation in V1-2 is associated with what looks like reciprocal ST depression in infero
RVH in Emphysema
Report:Sinus rhythm 96/min Right axis deviation +170o Right atrial abnormality Right ventricular hypertrophy Poor R wave progression Comment:The P wave axis is almost +90o and it has the tall peaked look of P pulmonale, with relatively uncommon init
Dextrocardia in Situs Inversus Viscerum
Report:Sinus rhythm 92/min Dextrocardia Nonspecific T wave changes Comment:Oddly enough the computer diagnosed âregular rhythm with unusual P axisâ, as though negative P wave in L1 is merely âunusualâ. It also went the full hog: âanterolatera
Holter Tape Stretch
Report:Sinus rhythm 68 â 70/min Paper speed or stretch artefact Comment:Variable, in this case fast, paper speed prolongs all the formed elements of the cardiogram to make them look like the last four complexes in this recording. The prolongation is i
Erythromycin Torsade de Pointes
Report:Sinus tachycardia 122/min Nonspecific T wave changes Prolonged QT interval Comment:This is one of those tracing where inspection is better than attempts at precise measurement and QTc calculation: there is a clear-cut long ST segment and the T w
