ECHO

Echocardiography (Echo)

An echocardiogram is also referred to as an echo or echocardiography. Echocardiography uses ultrasound high-frequency sound waves to produce detailed images of the heart. The most important function of the echo is to confirm the diagnosis of heart disease after a physical examination.

Electrocardiogram (ECG/EKG)

An electrocardiogram (ECG) is a safe and inexpensive way for a doctor to monitor a person's heart rate and rhythm. Electrodes (soft sticky patches) are attached to various parts of the body - the chest, wrists, ankles and back. These patches will conduct electrical impulses. The technician will apply a conducting gel to ensure a good connection. They will then hook the electrodes up to the machine and the test begins. It usually lasts less than one minute. The ECG simply records the heart's electrical activity.

 


HOLTER MONITOR

A Holter Monitor is a small portable device used for heart disease testing and for the assessment and diagnosis of chest pain. It is worn for a period of time to record the heart's rhythm - although it can also be used for monitoring brain activity. The device incorporates electrodes which are strapped to the chest and connect by wire to a monitor which records the heart’s activity. A Holter is usually worn for 24 to 48 hours and helps to diagnose heart arrhythmia, palpitations and causes of dizziness, chest pain and black out spells.


EXERCISE STRESS TEST

This test checks for signs of coronary heart disease (CHD). It can also be used to determine the prognosis (outlook) for patients with heart disease. A patient who has had a heart attack but can walk for 15 minutes on a treadmill without shortness of breath or chest pain is statistically likely to live longer than a patient who cannot.
