In some clinical settings, an apparent pacing system malfunction is suggested; however, the apparent malfunction is a normal, programmed pacer function. Such pseudomalfunctions are partly due to new algorithms to preserve intrinsic conduction and more physiologic pacing. These can sometimes be corrected by changing the programming; in other cases, the patient may need to have the device changed.
