Web24 de fev. de 2024 · Abstract. Since its introduction in 1972, the measurement of pulse volume recordings (PVR) has become an integral part of vascular laboratory diagnostic testing. The PVR measurements are often the 1st vascular test performed on a patient with suspected peripheral arterial disease (PAD) of the upper or lower extremities.
