Patient was interrogated and found an rv lead failure alert on the device.Low impedance measurements in bipolar and around normal measurements in unipolar were noted.Patient is not dependent.This could possibly be an inner insulation breach or fluid in the header.The rep was to get more information on patient's condition, to turn the device back to bipolar and take measurements.Second round of measurements show impedances in normal range.Device remains implanted and the patient will be monitored.
