Electrocardiography
Electrocardiography (ECG or EKG) is the process of recording the electrical activity of the heart over a period of time using electrodes placed on the skin.

Euclidean vector
In mathematics, physics, and engineering, a Euclidean vector (sometimes called a geometric or spatial vector, or—as here—simply a vector) is a geometric object that has magnitude (or length) and direction.

Heart
The heart is a muscular organ in most animals, which pumps blood through the blood vessels of the circulatory system.

Heart arrhythmia
Heart arrhythmia (also known as arrhythmia, dysrhythmia, or irregular heartbeat) is a group of conditions in which the heartbeat is irregular, too fast, or too slow.
New!!: T wave alternans and Heart arrhythmia · See more »
Myocardial infarction
Myocardial infarction (MI), commonly known as a heart attack, occurs when blood flow decreases or stops to a part of the heart, causing damage to the heart muscle.

NASA
The National Aeronautics and Space Administration (NASA) is an independent agency of the executive branch of the United States federal government responsible for the civilian space program, as well as aeronautics and aerospace research.

T wave
In electrocardiography, the T wave represents the repolarization, or recovery, of the ventricles.
New!!: T wave alternans and T wave · See more »
Ventricular tachycardia
Ventricular tachycardia (V-tach or VT) is a type of regular and fast heart rate that arises from improper electrical activity in the ventricles of the heart.
