Barack and Michelle Obama did not adopt either of their two daughters. Perhaps you are thinking of Mr. Obama's 2008 opponent, John McCain-- he and his wife Cindy did adopt a lâ¦ittle girl from Bangladesh.
The test itself will take about 30-60 minutes. Placing the electrodes usually takes 20 minutes, but can take up to an hour, so the entire procedure may take about one to 2 hours. If you have an ambulatory EEG, brain activity is recorded for 24 hours or more.
These electrical signals are sent to the ECG machine, where they are processed, and printed out as an âECG tracing.â The electrodes are then removed. The ECG test takes less than 5 minutes to perform. What Does the ECG Tracing Look Like? The picture on this page shows a typical, normal ECG. The electrical signals generated from the ten electrodes have been processed into 12 âviewsâ of the heartâs electrical activity - the so-called 12-lead ECG.
