Abstract:
Proper interpretation of the spectral Doppler signal and elucidation of the underlying hemodynamics can at times be problematic due to confounding factors, one of them being a rapid heart rate. In this article, we discuss the use of carotid sinus massage (CSM) in the echocardiography laboratory as a maneuver to reduce the resting heart rate and thus render the transmitral Doppler signal more amenable to analysis. We provide examples of the value of the CSM in the assessment of left ventricular filling pressure.

Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for...

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...
