Vijayaraman et al. (2002) conducted a case report in Runaway pacemaker malfunction (n=2). Undetected battery depletion was evaluated. Undetected battery depletion in two patients with single chamber pacemakers caused runaway stimuli at 2,400 and 2,600 ppm, which resolved uneventfully after emergency pulse generator replacement.
