Imaging + ECG Flashcards
What is the purpose of a transabdominal ultrasound?
Non-invasive imaging of liver, gallbladder, kidneys — identifies masses, cysts, fluid, hydronephrosis, or biliary obstruction.
What can a chest X-ray detect in this context?
Pneumonia, pleural effusion, pulmonary oedema, pneumothorax, cardiomegaly — may identify signs of systemic illness or sepsis source.
What can an abdominal X-ray reveal?
Bowel obstruction (dilated loops, air-fluid levels), perforation (air under diaphragm), faecal loading, or free gas.
What are limitations of plain abdominal X-rays?
Poor soft tissue contrast, less sensitive than CT for many abdominal pathologies — used mainly for obstruction, constipation, or free air.
Why was an ECG ordered?
To assess cardiac status — sepsis, electrolyte disturbances, or drug toxicity can cause arrhythmias or myocardial strain.
What ECG changes may be seen in sepsis or systemic illness?
Sinus tachycardia,
What are the common causes of sinus tachycardia on ECG?
Fever, infection, dehydration, anxiety, pain, anaemia, hypoxia, or medications.
