Electrocardiogram (ECG)

An Electrocardiogram known as an ECG is a test that records how your heart beats and provides results showing your heart's electrical activity. The ECG machine uses Electrode patches which are attached to your skin to measure the electrical impulses given off by your heart. It can give information of previous heart attacks or problems with the heart rhythm.

Duration: Usually 10 minutes

Holter Monitor

A Holter monitor is a small, wearable device that records the heart's rhythm. It's used to detect or determine the risk of irregular heartbeats (arrhythmias).

A Holter monitor test may be done if a traditional electrocardiogram (ECG or EKG) doesn't provide enough details about the heart's condition. If the irregular heartbeats are infrequent, a longer term monitor called an event recorder may be needed.

Echocardiogram

Echocardiography is also referred to as cardiac ultrasound and is performed by a specially trained technician. This test  uses sound waves to generate images of your heart that are displayed on a monitor.

During the test, you generally lie on your back or left side; gel is applied to your skin to increase the conductivity of the ultrasound waves. A technician then moves the small, plastic transducer over your chest. The test is painless and can take from 20  to 40 minutes. The machine analyses the information and produces the images which are then  reported  by the technician and reviewed by the cardiologist who will provide a final report .

Echocardiography can help in the diagnosis of many structural heart problems including assessment of the size of the chambers and pumping action of the heart, defining the extent of previous heart attacks, assessing valve disorders, holes between heart chambers.
