ECG

Introduction

An Electrocardiogram (ECG) is a safe, quick, and painless test that measures the electrical activity of your heart. By placing small electrodes on the chest, arms, and legs, the test provides information about your heart's rate, rhythm, and overall electrical function. It is commonly used to check heart health, diagnose heart conditions, or monitor ongoing cardiac problems.

Clinical Significance

An ECG is one of the most commonly performed heart tests because it helps doctors identify a wide range of heart-related conditions. It can help:

● Detect irregular heartbeats (arrhythmias)

● Identify signs of a current or previous heart attack

● Diagnose electrical conduction problems, such as heart block

● Detect an enlarged heart

● Evaluate symptoms like chest pain, palpitations, dizziness, fainting, or shortness of breath

● Monitor heart conditions and assess the effects of certain heart medications

● Check heart health before surgery or as part of a routine cardiac evaluation

Interpretation

ECG results should always be interpreted by a healthcare professional along with your symptoms and medical history.

● Normal ECG: Indicates that the heart is beating at a normal rate and rhythm, with proper electrical conduction.

● Abnormal ECG: May suggest an irregular heartbeat, reduced blood flow to the heart, heart muscle damage, conduction abnormalities, heart enlargement, or electrolyte imbalances.

An abnormal ECG does not always mean you have a serious heart condition. Depending on your results, your doctor may recommend additional tests, such as an echocardiogram, stress test, Holter monitor, or blood tests, to make an accurate diagnosis and decide on the best treatment.
