Pseudo pacemaker stimuli.
Current electrocardiographic technology is limited in its ability to detect pacemaker stimuli secondary to the use of 150 Hz low-pass bandwidth filters designed to block high-frequency interference. Software solutions to improve the sensitivity of pacemaker stimulus detection are associated with imperfect specificity. The following case reports include three patients who do not have a pacing device, but were identified by a computer-based preliminary interpretation of a routine 12-lead surface electrocardiogram (ECG) as having a paced rhythm.
