ECG (Electrocardiogram)
Instant reading of your heart's electrical rhythm.
An ECG records the electrical signal that makes your heart beat, using small sensors placed on your chest, arms, and legs. It takes about five minutes and causes no discomfort — no needles, no dye. The resulting trace tells your cardiologist whether your heart's rhythm is regular, whether any part of the heart muscle has been damaged in the past, and whether there are signs of strain that need further testing.
Types of ECG (Electrocardiogram)
Resting ECG
The standard test — a snapshot of your heart's rhythm while you lie still for a few minutes. Used for most routine and emergency checks.
Holter Monitor (24–48 hr)
A portable ECG worn for a full day or two to catch irregular heartbeats that come and go, which a five-minute test might miss entirely.
Frequently asked questions
Does an ECG hurt?+
No. Small adhesive sensors (electrodes) are placed on your skin — there's no needle and no discomfort involved.
How quickly will I get my ECG results?+
A resting ECG is read immediately by our cardiology team, usually within minutes of the test. A Holter monitor's results take longer since it records data over 24-48 hours.
Can an ECG detect a heart attack?+
Yes — an ECG is one of the fastest ways to detect signs of an ongoing or past heart attack, which is why it's a standard first test for chest pain.
Do I need to remove jewelry or fast before an ECG?+
No fasting is needed. You may be asked to remove jewelry or clothing from the chest area so the sensors make proper skin contact.
