Electrocardiography was invented in by Dutch Nobel Laureate Willem Einthoven, who, it should be noted, spelled electrocardiogram with a C.
However, when he translated his work into German, it became elektrokardiogramm, which is the origin of the abbreviation EKG. Electroencephalogram EEG is a test that measures electrical impulses in your brain through little metal discs called electrodes stuck to your scalp.
The electrical signals in your brain, or brain waves, are recorded in peaks and valleys on the graph. Lots of rapid spikes can indicate a seizure or epilepsy , while very slow brain waves can suggest a tumor or a stroke. An EEG is an electroencephalogram, and it measures the electrical activity of the brain. It can help detect and diagnose diseases by revealing abnormal brain impulses. For example, a seizure would appear as abnormal spikes and sharp waves on an EEG.
Your doctor will connect wires to your scalp using flat, metal disks called electrodes. On the other hand, you may stay overnight for an EEG, or take a special recorder on the go with you for up to three days.
These tests measure the electrical activity in your body to help make a diagnosis, but they do not send electrical activity into your body.
Speaking of diagnoses, check out the difference between a diagnosis and prognosis here. July 22,
