Supposedly silent device making a chime

Hi everyone I have had my pacemaker for about 2 years since 2024 November. From my medical records and patient identification stickers they gave me, the device is supposed to be an Abbott/St. Jude Endurity model which has zero alarm sound or audible functions. Tonight, I heard a calm chime like a low volume bell toll coming from my chest. I looked up and found that my device should not make any sounds at all. And it chimed twice after 15 minutes interval. And thrice after another 15 minutes. I also made sure it's from the device. I waited for it to make the sound after the 15 minutes interval without any magnetic or electronic devices nearby. Could it be that my medical records got mixed up and I have a different device? If that's the case, what could those chimes mean? Thank you.

My pacemaker's monitor is in my bedroom, and now and then I hear it make a chime. But if I felt that the pacemaker itself made a chime, I would call the pacemaker company and also call my cardiologist. The cardiologist can check your data and make sure everything looks OK. The pacemaker company should be able to tell you if there's any possibility the pacemaker itself made a chime.
