UP3, Galvanic Skin Response and pacemaket

I am considering purchasing a Jawbone UP3, which includes a sensor for galvanic skin response (GSR), commonly known as skin conductance. The product is a band that is worn around the wrist near the hand. It "measures the resistance of body tissue to tiny electric current to enable the capture of a wide range of physiological signals including your heart rate."

The only details about how it works that I have found are at https://jawbone.com/blog/up3-advanced-multi-sensor-technology/. It says:

"The visible part of the bioimpedance system is the set of four electrodes embedded into the flexible strap. All four electrodes work in sync to form a tetrapolar (4 pole) system. Two outer electrodes drive tiny electrical energy and the two inner electrodes pick up changes in voltage. Amazingly, the resultant signal (which is imperceptible to the wearer) contains rich data about your physiology."

Do you know if this would be dangerous or a problem for my pacemaker? It almost never paces (<.01% of the time -- which is the lowest on the scale).

GSR

No worries. I have used GSR as a biofeedback therapist. The amount of current is so tiny that located on your wrist, it would have no effect at all on the PM.

We forget that throughout our bodies, micro currents are constantly being generated by our muscles, our brains, and yes, our own hearts.Our very body is an electrical system. Pacemaker designers have already figured that in.

Thank you

Thank you, Gotrhythm, very much.
