  • Coronary angiography demonstrated no coronary artery disease, but left ventricular angiography showed marked apical ballooning and apical wall akinesia consistent with a diagnosis of takotsubo cardiomyopathy.[ncbi.nlm.nih.gov]


  • Depending on the results of your examination, you may require further workup in the form of scans, blood work or biopsies. Many different treatment options are available depending upon your diagnosis.[hopkinsmedicine.org]
  • Septic workup should likely include a chest X-ray, labs including lactate, VBG, and blood cultures. Get your “double set up” airway equipment to the bedside.[emergencymedicinecases.com]
  • . • Investigations add little in the initial workup • As viral croup is the commonest cause of UAO, attempts to identify other causes is also very important to confirm the diagnosis. 16.[slideshare.net]
T Wave Inversion
  • A 12-lead electrocardiogram showed widespread T-wave inversion and QT prolongation suggestive of an acute coronary syndrome.[ncbi.nlm.nih.gov]


  • AP2, prior to FP treatment, was enriched with Streptococcus pneumoniae.[ncbi.nlm.nih.gov]

  • Laryngeal atresia is an extremely rare fetal anomaly with dismal prognosis. It is important to differentiate the condition from other lesions with a more favorable prognosis, such as congenital adenomatoid malformation of the lung.[ncbi.nlm.nih.gov]

  • See Figure 2 for a comparison of what 1 mm of circumferential edema does in terms of airway resistance to an infant and an adult Pathophysiology Upper airway obstruction can occur for a variety of causes, but fundamentally, leads to increased airway resistance[learnpicu.com]
