An Electrocardiogram (ECG or EKG) is a simple, non-invasive test that records the electrical activity of the heart.
An Electrocardiogram (ECG or EKG) is one of the most common and important heart tests used in healthcare. It is a quick, safe, and non-invasive test that records the electrical activity of the heart and produces a graph of voltage against time. This graph helps doctors study your heartbeat, rhythm, and overall heart health.
During an ECG test, small electrodes are placed on your chest, arms, and legs. These detect the electrical signals from your heart, which are then displayed on a monitor or printed on paper.
Doctors use this test to detect and monitor:
● Heart attacks (current or past)
● Irregular heartbeats (arrhythmias)
● Other heart diseases and conditions
An ECG test helps in:
● Diagnosing heart attack symptoms early
● Identifying abnormal heartbeat or arrhythmias
● Checking how well pacemakers or other treatments are working
● Monitoring the progress of heart disease treatments
Your doctor may recommend an ECG if you have:
● Chest pain or pressure
● Palpitations (pounding, skipping, or fluttering heartbeat)
● Dizziness, fainting, or confusion
● Shortness of breath
● Weakness, fatigue, or reduced ability to exercise
● A fast or irregular pulse
Even without symptoms, an ECG may be suggested if you:
● Have a family history of heart disease
● Are at risk for conditions like high blood pressure, diabetes, or high cholesterol
● Need a routine heart screening as part of a health check-up
● Quick and painless
● No recovery time needed
● Provides vital information about your heart’s electrical function
● Helps detect problems before they become serious
Whether you have symptoms, risk factors, or just want a routine heart check-up, an ECG is
often the first step in heart care.
