Figure 1 Three electromagnetic interference (EMI) detections while in a saline-chlorinated pool. All noise detections were confirmed to occur during swimming. A: A characteristic 60 Hz pattern of EMI resulting in atrial noise detection and transient ventricular pacing inhibition (arrow) during swimming in a saline-chlorinated pool. B: Noise while in a saline-chlorinated pool resulting in inappropriate implantable cardioverter-defibrillator shock. The EMI is apparent on both the atrial and ventricular sensing channels. C: A second event of EMI in a single patient in a different saline-chlorinated pool with aborted therapy.
