An electrocardiogram (ECG or EKG) is a painless, low-cost test that records the heart's electrical activity, making it a standard diagnostic tool for analyzing arrhythmias. It shows parameters like heart rate, rhythm steadiness, and electrical signal strength within the heart. Doctors utilize ECGs to detect heart-related issues, translating the electrical activity into line tracings for analysis.

1. Electrocardiogram

2. What is an Electrocardiogram ?
 An electrocardiogram is a simple, painless test that records the
heart's electrical activity.
 It is a low-cost, noninvasive, and effective test for arrhythmia
analysis and has become the standard diagnostic tool.
 With each heartbeat, an electrical signal spreads from the top of
the heart to the bottom. As it travels, the signal causes the heart
to contract and pump blood.

3. Other names for ECG?
 An electrocardiogram also called an EKG or ECG.
 Sometimes the ECG test is called a 12-lead EKG or 12-lead ECG,
this is because the heart's electrical activity most often is
recorded from 12 different places on the body at the same time.

4. What an ECG Shows?
 How fast your heart is beating.
 Whether the rhythm of your heartbeat is steady or irregular.
 The strength and timing of electrical signals as they pass through
each part of your heart

5. How ECG is useful?
 Doctors use ECGs to detect and study many heart problems, such
as heart attacks, arrhythmias (ah-RITH-me-ahs), and heart
failure.
 An EKG translates the heart's electrical activity into line tracings
on paper.
 The test measures how electrical impulses move through the
heart muscle as it contracts and relaxes.
