Heart rate monitor, chest strap interfere pacemaker,, so running was impossible

Do heart rate sensors affect the functioning of pacemakers?

I was very uncomfortably slowed down while jogging today. Only after I turned the HF sensor to the opposite side of the thorax did the pacemaker function properly (Boston Scientific Proponent and Garmin HF sensor).

Nothing is published about this behavior. Only Garmin says St.JudeMedical have no such a problem.

But Garmin Hf Sensor interfere bostons Proponent, I experience that today , awkward!


Wish all peacefull pacing

Chest strap HR sensors measure Lead I - a passive pickup of the electrical activity of  the heart.  For many people they don't work well, as the ECG voltage for lead-I is quite low, so moving the position of the chest strap may give you something closer to one of the V-leads which are much higher voltage.  Teasing out the low voltage (at the skin) of your heart's electrical activity from the very much larger voltages generated by your skeletal muscles (thinking here about pectorals during running) is quite a trick.

Pulseox-type HR monitors simply shine some green light into/through your skin and detect the changes in absorption of light as the blood flows and detect your HR from that (not very well for most skin-contact pulseox gadgets during exercise).


Not the ChestStarpHrSensor get the problem, but the PM-Rate-Sensor was interfere from Chest Strap - BlueThooth?

PM holter Show completely dowregulation of the Sensorrate at the time of max discomfort, I was constrained to stop my run 3 times. After I turn the HF sensor on the opposite to Pm, I regain the fitness for running the next 8 miles and the holster show a sonsorrate of 135-140/ min mean. So my expirence is the Garmin bother the Boston 

We need to make sure that we're talking about the same thing

You refer to a HF sensor - which might not be a Heart Rate sensor but some other device.  Ordinary heart rate sensors - chest strap or pulseox will NOT interfere with your PM's operation.  Some other consumer devices may - the most obvious being scales that attempt to measure body fat percentage.

English may not be your first language, so perhaps something is being lost in translation.

You're sure that your actions achieved an improvement in PM operation: that may be correct or it may not.  The Romans warned against this: post hoc, ergo propter hoc.  The warning being that an event that follows another in time isn't necessarily causally related.

But you will believe what you want to believe.

Believe or expierence

Boston technical service:

As you may see from our online EMI Guide*,


...the recommendation for “Activity Tracker” or "Heart Rate Monitor" devices is to “Use Precaution” and keep minimum distance of 15cm from implanted device.
For any device in which the recommendation is to “use precautions”. Check with your doctor for detailed information before using these items. 

Use precaution: : Maintain 6 inches (15 cm) distance between chest strap or wrist monitor. Suggest rotating chest band to opposite side, away from device implant site.

I have a well tuned pacer. I hardly know I have it. I am 76 year old, hike and camp alone in the desert. I have more energy than I have had in a long time. The only problem is my wife wants to have a knob installed so she can turn the pacer down.
