What are ECG and its types ECG grids ECG leads segments

An electrocardiogram (ECG) is a simple assessment that can be used to check your heart's rhythm and electrical motion. Sensors committed to the skin are used to notice the electrical signals fashioned by your heart each time it beats. These signals are verified by a machine built by ECG Machine Manufacturers and are looked at by a doctor to see if they're unfamiliar. An ECG may be demanded by a heart specialist (cardiologist) or any physician who thinks you might have a problem with your heart, including your GP. The examination can be carried out by a particularly trained healthcare expert at a hospital, a clinic, or at your GP surgery. Despite having a parallel name, an ECG isn't the same as an echocardiogram, which is an examination of the heart.
When an ECG is used
An ECG is often used together with other examinations to help identify and monitor conditions affecting the heart. It can be used to examine signs of a possible heart problem, such as chest pain, palpitations (abruptly obvious heartbeats), dizziness, and shortness of breath.
An ECG can help notice:
arrhythmias where the heart beats too gradually, too rapidly, or erratically
coronary heart disease where the heart's blood source is blocked or broken up by a build-up of fatty substances
heart attacks where the source of blood to the heart is abruptly blocked
cardiomyopathy where the heart walls become condensed or distended
A sequence of ECGs can also be taken over time to monitor a person already identified with a heart condition or taking medicine known to potentially affect the heart.
Kinds of ECG
There are 3 chief kinds of ECG:

A resting ECG is carried out while you're reclining down in a contented position
A stress or exercise ECG is carried out while you're consuming a workout bike or treadmill
An ambulatory ECG (occasionally named a Holter monitor) the electrodes are linked to a small portable apparatus bought from ECG Machine Dealers worn at your midriff so your heart can be observed at home for 1 or more days
The kind of ECG you have will be contingent on your indications and the heart problem suspected.
For instance, an exercise ECG may be suggested if your symptoms are activated by physical activity, while an ambulatory ECG has done on equipment supplied by ECG Machine Supplies may be more suitable if your indicators are erratic and occur in accidental, short episodes.
