It was reported that when the analyzer was connected to the measurement cable in the ventricular channel, the r wave was not sensed, and the impedance measurement showed above 400 ohms.The atrial channel was then verified, and sensed wave value was displayed, and the impedance was as expected.The analyzer cable was changed but this failed to improve the issue.The analyzer was then changed out for an alternative and the case could then be completed.No patient complications have been reported as a result of this event.
