data transfer technic like Bluetooth, a risc of interference?

...what is about the data transfer technic from all the stuff, we use, like bluetooth or other? Are the monitors, chest straps, headphones, watches, handys really passiv?

Bosoton says:

Use precautions: As this wireless technology usually uses Bluetooth, maintain at least 
a 6 inch (15 cm) separation between the activity tracker and implanted device due to 
Bluetooth technology. This is a device or application that may track steps taken, 
distance walked or run, calories consumed, and in some cases heartbeat and quality 
of sleep. The tracker may be synchronized, in many cases wirelessly, to a computer or 
smartphone. In some activity trackers, heart rate is measured 2 ways: 1) By LED lights 
which reflect onto the skin to detect blood volume changes or 2) by using a chest 
strap which measures and sends the heart rate to a wrist watch.

Data transfer

Yes, modern pacemakers use Bluetooth/LP as their communications technology.  This interface can only be used for remote interrogation.  It cannot be used to modify anything in the PM for secutity reasons.  To modify anything in the PM, near-field communications is used and only in the cardiologist's office (usually by the PM tech).

The warnings are just that.  They're covering their collective butts by making such dire warnings.  The conservative approach is not to use anything with Bluetooth.  That's what the lawyers would like to say. "Take no chances".

Since the pacemaker only uses Bluetooth to report to the base station during a remote interrogation, interferrence with the Bluetooth channel would be irrelevant for everyday operation.  The worst case is that a transmission would be missed.  Bluetooth is designed to work with Bluetooth interferrence (in fact, all 2.4GHz wireless technology). It's quite robust, considering how cheap it is to implement.

No, Bluetooth interferrence is right down there at the bottom of my concerns. And, I don't have a long list of concerns that aren't at the bottom.

My personal experience with Garmin HRM chest straps (which uses bluetooth as well as ANT+) and even having my iphone (by accident) in a chest pocket over the PM was that absolutely nothing happened at all to the PM, functioning normally at rest and with exercise.

iPhone over PM

Not a good idea!

The iPhone magnet can potential interfere the PM, sure!

Your doc use the effect to manage PM-function.

I take my iPhone in a arm-bag on the other side from PM 

Scientific investigation have shown, that the iPhone must be direkt over PM without any distance for interference ...
