What is the most probable origin of stroke?
After waking up at 6 a.m., a 74-year-old male patient’s wife noticed that her husband couldn’t speak and was unable to move his right extremities. She saw him last at 2 a.m. when her husband went to the toilet and was symptom-free. She called the family doctor, who measured 180/110 mmHg blood pressure and 88/min heart rate. They called the ambulance and arrived at the hospital by 8 a.m. Status: pulmonary emphysema, fundoscopy showed hypertensive retinopathy, right sided central facial palsy, right sided hypotonic, severe hemiparesis predominantly in upper extremities, increased deep tendon reflexes, complete motoric, severe sensoric aphasia. ECG: atrial fibrillation. Electrolytes and blood sugar levels were within the normal ranges.
A) hemodynamic
B) cardioembolic
C) atherothrombotic
D) artery to artery embolisation
B) cardioembolic
ECG monitoring in acute phase of stroke is necessary, because stroke may cause cardiac arrythmia.
