With color Doppler, different colors are used to designate the direction of blood flow. Color Doppler is an enhanced form of Doppler echocardiography.
Also, Doppler can detect abnormal blood flow within the heart, which can indicate a problem with one or more of the heart's four valves, or with the heart's walls.Ĭolor Doppler. The amount of blood pumped out with each beat is an indication of the heart's functioning. This Doppler technique is used to measure and assess the flow of blood through the heart's chambers and valves.
M-mode echo is useful for measuring or viewing heart structures, such as the heart's pumping chambers, the size of the heart itself, and the thickness of the heart walls.ĭoppler echocardiography. This, the simplest type of echocardiography, produces an image that is similar to a tracing rather than an actual picture of heart structures. These sound waves are sent to a computer that can create moving images of the heart walls and valves.Īn echocardiogram may use several special types of echocardiography, as listed below:
GSWITCH 2 NOT DOPPLER SKIN
When the transducer is placed on the chest at certain locations and angles, the sound waves move through the skin and other body tissues to the heart tissues, where the waves bounce or "echo" off of the heart structures.
During the procedure, a transducer (like a microphone) sends out sound waves at a frequency too high to be heard. An echocardiogram is a noninvasive (the skin is not pierced) procedure used to assess the heart's function and structures.
