This is harmless, high frequency "ultrasound" which cannot be heard by human ears.)The different echoes returning from the surfaces of the heart and other structures are then electronically plotted and recorded.

These signals create an echocardiogram, a graphic image of the heart and blood vessels.This can yield useful information about these structures, such as the size, shape and motion of the heart chambers,great vessels and heart valves.

Ultrasound technology is also utilized to evaluate patients for atrial septal defects as the possible cause of intractable migraine headaches, transient ischemic attacks and cryptogenic stroke.

Pre-Procedural Instructions

THE TEST TAKES APPROXIMATELY 1 HOUR

WHAT WILL HAPPEN TO ME:

Electrodes are placed on your chest and shoulders to monitor your heartbeat. You then lie down on an exam table. The technician will move the transducer (the part of the equipment that sends the ultrasound waves that image your heart) over your chest and take pictures of your heart in various positions. These images are recorded on videotape and sent to your doctor for review.

INSTRUCTIONS:
Prior to the test, you may eat, take your medications, and go about your normal activities without change, unless you are told to do otherwise. After the test, you may return to your normal activities.
