Left Ventricle Mid-Posterior to Anterior Septal Time to Peak Systolic Wall Motion Velocity (LV Mid-Posterior to Anterior Septal TTV)

What This Test Measures

The test uses ultrasound waves to track the movement of your heart muscle fibers. By measuring how quickly these fibers shorten (contract) and relax (during systole), doctors can detect abnormalities in how your heart pumps blood to your body.

Why It’s Done

Doctors may order this test if you have symptoms like shortness of breath, chest pain, or fatigue, or if they suspect conditions like heart failure, coronary artery disease, or other structural heart problems. It’s also used to monitor heart function before or after treatments like surgery or medications.

How It’s Performed

You’ll lie on an exam table while a technician applies a gel to your chest. A small device (probe) moves over your chest to send sound waves into your heart. The probe records the movement of your heart muscle, creating images that show how fast it contracts and relaxes.

Preparation

No special preparation is needed. You may be asked to fast for a few hours before the test if you’re also having other blood tests, but this isn’t always required. Wear comfortable clothing and avoid heavy exercise on the day of the test.
