The ECG showed sinus bradycardia with striking early repolarization, ST segment elevation, and peaked T waves. These ECG abnormalities represent an unusual pattern for beta-adrenergic blocking agent toxicity.Grant R GwinupAnnals of Emergency Medicine...
A 70-year-old woman with a history of hypertension, diabetes and renal disease presented to the emergency department complaining of diffuse weakness for 24 hours. On examination, vital signs showed a normal temperature, pulse 100 beats/min, respiratory rate 25 breaths/min, pulse oximetry 97%, ...
Wellens syndrome describesa pattern of electrocardiographic (ECG) changes, particularly deeply inverted or biphasic T waves in leads V2-V3, that is highly specific for critical, proximal stenosis of the left anterior descending (LAD) coronary artery. It is alternatively known as anterior, descending,...
BackgroundTall, symmetrically peaked T waves commonly appear throughout the precordium (V1 to V6) as serum K+ rises above 5.5 mmol/L. During routine ECG analysis, we found such T waves, but they were confined to V1-3. We then ascertained these tracings belonged to a group of patients...
