Diagnosis of Stroke
Tests to Evaluate Stroke and Effect of Stroke
- Electroencephalogram (EEG)—to measure electrical activity of the brain via electrodes placed on your head
- Evoked response test—to measure how your brain processes sensory information
Tests to Evaluate the Heart
- Electrocardiogram (EKG)—To test the heart's electrical activity by measuring electrical currents through the heart muscle. A healthy heart creates a specific pattern on an EKG. A previous heart attack and heart damage will cause disruptions to this pattern. It can also be used to diagnose atrial fibrillation .
- Electrocardiogram —Ultrasound detects abnormalities in the heart muscle by highlighting areas of poor blood flow.
- Holter monitor—A small machine is belted around your waist and will record your heart rhythm over a period of 24 hours or more. It may be able to detect any rhythm abnormalities after a stroke.
