ECG
An electrocardiogram (ECG) is a test that records the electrical activity of the heart.
ECG is used to measure the rate and regularity of heartbeats as well as the size and position of the chambers, the presence of any damage to the heart, and the effects of drugs or devices used to regulate the heart (such as a pacemaker). ECG is the best way to measure and diagnose abnormal rhythms of the heart. The ECG is often used as a preventive investigation for cardiovascular (heart) diseases.
Cardiovascular diseases continue to be the most frequent cause of death in industrialised countries. Worldwide, cardiovascular disease is responsible for one in every three deaths – which translates into 17 million people worldwide each year. By 2020, the WHO estimates the death toll from cardiovascular disease will have risen to nearly 25 million worldwide. Cardiovascular disease is a general term for disorders affecting the heart and blood vessels.
These include:
coronary artery disease
heart attack
stroke
hypertension
peripheral vascular disease
chronic heart failure
angina pectoris
arrhythmia
By the time that heart problems are detected, the underlying cause (atherosclerosis) is usually quite advanced having progressed for decades. There is therefore increased emphasis on preventing atherosclerosis by modifying risk factors, such as healthy eating, exercise, and avoidance of smoking.
