Normal swan waveforms
WebPulse Volume Recording. Pulse volume recordings (PVR) are a non-invasive imaging test that evaluates the lower or upper extremity arterial flow. This test is actually the more complete form of ankle brachial index. This is because PVR’s test the pressure ratio along the limb and not just at the end. The pulse volume recording test is functional.

ECG interpretation traditionally starts with an assessment of the P-wave. The P-wave reflects atrial depolarization (activation). The PR interval is the distance between the onset of the P-wave to the onset of the QRS complex. The PR interval is assessed in order to determine whether impulse conduction from the …
