An electrocardiogram is a test tha doctors use to assess cardiovascular health. what type of data is recorded by the electrocardiogram

The Electrocardiogram is a test that is used to measure the electrical activity of the heart. Each and every heartbeat is initiated by the electrical signal which is initiated from the SN (Sinoatrial) node, which is present at the top of the heart and travels to end of the heart.

An ECG monitors the electrical activity of the heart and gives a result as a moving line of peaks and dips. Actually, it measures the electrical current that is running throughout the heart and tells the doctor about the function of the heart.

It is used to detect the problem of the heart such as heart attack, abnormal heart rhythm, enlargement of the heart etc.

The Electrical Activity of the Heart (.D

Explanation:

This is the correct answer for Plato (:

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.
