Malfunction of a dual chamber system pacemaker due to a current leak in the output circuitry leading to a rapid decline in battery longevity is described. Serial pulse amplitude alterations in defined device configurations enabled location of the defect in the 2.5‐V output voltage level; the current leak disappeared in the 5‐V output voltage level, and recurred in the 7.5‐V output voltage level which combines both 2.5‐V and 5‐V output circuitries. Reprogramming of pulse amplitudes rectified device malfunction. Circuitry reprogramming of pacemakers with faulty unexplained high battery current can circumvent early replacement in management of device malfunction.
