Remote Monitoring of Your Pacemaker, ICD, or Loop Recorder

Your implanted device quietly checks itself and sends reports to our office — often while you sleep. Here's what it transmits, what it can and can't do, and why keeping the monitor connected matters.

What remote monitoring is

Modern implanted heart devices are small computers. In addition to doing their job inside your chest, they keep a detailed log of your heart rhythm and their own health — battery, leads, and any treatments they’ve delivered. Remote monitoring is the system that gets that information from your device to our office without you having to come in for every check.

Most patients have one of two setups:

  • A bedside monitor that sits on a nightstand and communicates with your device automatically, usually overnight while you sleep.
  • A smartphone app that pairs with the device and does the same thing.

Either way, for most transmissions you don’t have to do anything — it happens in the background.

What your device sends

  • Scheduled transmissions — a routine “check-in” at set intervals (often every 1–3 months) that replaces some in-office visits.
  • Alert transmissions — if the device detects something it’s programmed to flag, it sends a report right away, such as:
    • An episode of an abnormal rhythm (AFib, fast ventricular rhythms)
    • Any shock delivered by an ICD
    • A change in a lead or a drop in battery
    • For loop recorders: rhythm events it was placed to catch

Why it’s worth it

  • Earlier answers. Problems are often caught days to weeks sooner than waiting for the next office visit — sometimes before you feel anything.
  • Fewer trips. Many routine checks can be done from home, which matters most for patients who travel or live far away.
  • Better information after an event. If you have palpitations or feel a shock, we frequently already have the recording in hand when you call.

What it does not do

This is important: remote monitoring is not real-time emergency monitoring. No one is watching your heartbeat live, second by second. Transmissions are reviewed during office hours, and even “alert” transmissions are not a substitute for emergency care.

  • For any emergency — fainting, chest pain, severe shortness of breath, or repeated ICD shocks — call 911. Don’t wait on a transmission.
  • It also doesn’t replace all in-office visits; we still see you periodically to examine the site and adjust settings.

Your part

The system only works if your device can reach us:

  • Keep the bedside monitor plugged in and turned on, ideally within a few feet of where you sleep.
  • If you use the phone app, keep it installed, signed in, and your phone charged; keep Bluetooth on.
  • Traveling? Many monitors work on the go — ask us, and bring it (or your phone) with you.
  • If your monitor shows a connection problem you can’t fix, let us know.

Your privacy

The data is your protected health information and is transmitted securely to our practice. It’s used to take care of you — the same as the information from an in-office device check.

How it fits with your visits

Think of remote monitoring as the steady background check and your office visits as the hands-on review. Together they let us follow your device closely while keeping your trips to the clinic to what’s truly needed. If a transmission turns up something that needs attention, we’ll reach out — and you should always feel free to call us with questions about an alert you’ve seen on your monitor or app.
