Electrocardiography, commonly referred to as an electrocardiogram or ECG, is a medical test used to record the electrical activity of the heart over a period of time. This non-invasive test is used to diagnose and monitor various heart conditions, including arrhythmias, heart attacks, and cardiomyopathy.

During an ECG, electrodes are placed on the patient's body, typically on the chest, arms, and legs. These electrodes detect the tiny electrical signals produced by the heart as it beats and transmits them to a machine that records the signals on a paper strip or digital display. The resulting tracing shows the heart's electrical activity, including the P-wave, QRS complex, and T-wave.

ECGs can be performed in various settings, including hospitals, clinics, and doctor's offices. The test typically takes only a few minutes to perform and is relatively painless. There are two main types of ECGs: resting ECGs, which are performed at rest, and stress ECGs, which are performed on an exercise bike or treadmill to assess the heart's response to physical stress.

The information recorded during an ECG can help healthcare professionals diagnose and manage a range of heart conditions, including:

* Arrhythmias, such as atrial fibrillation and ventricular tachycardia

* Myocardial infarction, or heart attack

* Cardiomyopathy, a condition in which the heart muscle becomes weakened

* Heart valve problems, such as mitral regurgitation

In addition to its diagnostic uses, ECGs are also used in various medical settings to monitor patients with implants, such as pacemakers and defibrillators, and to guide the administration of medications and treatments.
