An electrocardiogram (ECG) is a test which measures the electrical activity of your heart to show whether or not it is working normally. An ECG records the heart's rhythm and activity on a moving strip of paper or a line on a screen.
An echocardiogram (echo) is a graphic outline of the heart's movement. During an echo test, ultrasound (high-frequency sound waves) from a hand-held wand placed on your chest provides pictures of the heart's valves and chambers and helps the sonographer evaluate the pumping action of the heart
Treadmill ECG is a test to see any significant blockage to the heart circulation. It involves walking on the treadmill while your blood pressure, hert rate and rhythm and symptoms are being monitored.
This test is a combination of Stress ECG and Echocardiogram. The ultrasound of the heart is done before and after the patient walks on the treadmill. This test is indicated if Treadmill Stress ECG alone is not sufficient to determine the presence of blockage in the heart circulation.
Dobutamine Stress Echocardiogram
This test also checks for blockage in the heart circulation but it is indicated for patients who cannot tolerate walking on a treadmill. An intravenous solution ("drip") containing the drug Dobutamine is attached to the patient. Dobutamine stimulates the heart to beat fast similar to what walking on a treadmill would do. Images of the heart are then taken at different intervals right through the test. The patient's heart rate, blood pressure and symptoms are stricly monitored all through out the test.
Commonly called "heart monitor". It is a continues ECG monitoring . A small device is attached the patient which will record the heart rhythm for 24/48/72 hours depending on the doctor's request. The patient goes home with the device along with a diary to write down any symptoms he/she might feel during the course of monitoring. After 24/48/72 hours, the patient comes back wiith the device for removal. Our cardiovascular technician will then download the recordings in our system for our cardiologist to interepret.
A bubble echocardiogram is the same procedure as an echocardiogram, except an IV is placed in the patient's arm. During certain portions of the imaging, saline with bubbles is injected into the vein.
