I had a loop monitor as part of my AFib clinical trial regarding Pulsed Frequency Ablation and it was inserted just under the skin on my left upper chest. It was hard noticeable and paired with a Boston Scientific-supplied smart phone that collected the data and transmitted it to a remote database. When traveling I took the smartphone, plus a card stating what the loop recorder was and the only limitation was that security couldn’t wand the recorder directly. No other restrictions. Get the loop recorder.
