ECG and Echocardiogram

What it involves

An electrocardiogram (ECG) records the electrical activity of the heart through small sticky sensors placed on the chest, arms and legs. An echocardiogram uses ultrasound to produce moving images of the heart, showing its size, structure and how it pumps. Neither involves radiation.

Who it is for

They are for people being assessed for symptoms such as chest pain, palpitations, breathlessness or dizziness, those with high blood pressure or heart disease, and sometimes before surgery or as part of a health check. A doctor decides which test is appropriate.

How long it usually takes

An ECG commonly takes around five to ten minutes. An echocardiogram usually takes longer, often around half an hour to an hour.

What to expect

For an ECG you lie still while the sensors record your heart. For an echocardiogram, gel is applied to the chest and a probe is moved over it. Most people find both comfortable, though the sensors may pull when removed. A specialist reads the results and your doctor explains them.

Aftercare

There is no recovery time. You can usually return to normal activities. Ask how and when the results will be shared with you and your doctor.

When to seek it

A doctor may suggest these tests if you have symptoms or risk factors. Sudden chest pain, severe breathlessness or fainting needs emergency medical attention rather than waiting for an appointment.

What affects the cost

Cost depends on which test is done, whether a specialist report is included, the setting and whether a consultation is part of the visit. HealthNaro shows a price only where a clinic has supplied a figure with a source and date.
