It's okay to pass through security systems that use metal detectors, just be sure to walk at a normal pace. There are typically 2 types of detectors: 1. Full body scanners present a low risk of interference with the ICD. 2. A hand wand can be passed over the ICD, but it should not be held directly over it. You need to let the security agent know you have a medical device implant. Carry the ID card from your device manufacturer whenever you're traveling.
