Pulse Volume Recording (PVR)

Pulse Volume Recording (PVR) is a noninvasive vascular test that combines a blood pressure check with Doppler ultrasound to measure arterial blood flow in the arms and legs. Ankle brachial index (ABI) is a PVR test used to detect peripheral arterial disease (PAD).

The ABI measures blood pressure in your lower leg and compares it to the blood pressure in your arm. In the absence of disease, blood pressure in your ankle and arm should be about the same. But if your ankle pressure is half your arm pressure or lower, it could be a sign of PAD, a condition that causes poor circulation in your legs due to the narrowing of arteries.
