As long as the pace maker is not wireless, and you don’t put any wireless devices inside the tent, and if the grounding is good, it should be better than outside the tent.
Usually for beds, most use RF blocking canopy from Naturell fabric – https://www.4ehsbyehs.com/product/rf-blocking-canopies/

Shalom Amir, I bought these portable tents from Dr mercola a few years ago, they are grounded, my wife has a pacemaker, is that considered a electronic device inside a grounded tent a good idea, if it’s a bad idea, can you recommend a tent fabric that would be a good idea, we a queen size bed?

Hello
Thanks for the comment, sorry for the late reply, hope it will still be of help.

Hello and sorry to hear about your situation.
First I would recommend getting the CORNET ED88TPLUS meter.
Then to start the process of testing& measuring EMF (RF, ELF magnetic, and ELF Electric fields, also Dirty Electricity) in your house.
Try to allocate the sources of EMF radiation in your house and reduce the exposure.
Then try to find the penetration points of RF and ELF radiation into your house.
Then and only then we can suggest how to protect the house and bedroom, and which protection products to get.

My Answer:
***************
Hello
Thank you for your email.
Your question is important so I will publish this answer on the sites, without your personal info.
EMF personal protection, and EMF home protection, and EHS gear are not blocking all forms of EMF or RF radiation.
If used correctly, the protection will reduce user exposure to the type of EMF it is designed to reduce.
The right way to test the reduction in exposure is by using an EMF meter, not by a cell phone.
Please see – https://www.norad4u.com/emf-protection/personal-rf-protection/

Protection from what?
The Personal Protection and EHS Gear are meant to be used by Electromagnetic HyperSensitive(EHS) people who already stopped using their wireless and cellular devices and already reduced their exposure by other means. The protection is meant to reduce exposure from environmental sources that the person can’t control in any other way, like cell towers and neighbors’ wireless equipment, It is not meant to stop “attacks of any type”.

ELF Magentic Proteciton
The Hats, Fabric, Sleeping bag, and Canopies will all reduce the user’s RF exposure, but not ELF magnetic field.
We don’t have a product that reduces user exposure to ELF magnetic fields.

Canopies
The canopy itself is the last step in RF protection for EHS people.
It is made out of RF Blocking fabric that when new, blocks more than 99% of the RF.
In order to achieve this level of blocking the canopy should be closed and sealed.
Also, the RF protection should be but also on the floor, and the canopy would touch the protection on the floor (they should over lap).
If not overlapping some RF will come in from the opening.
In addition, the fabric is delicate, and if washed or used incorrectly will lose it’s RF blocking qualities.
In some cases, WIFI/Cellphone signals will still be working after 99% reduction in strength.
Please see the Canopies product’s page – https://www.4ehsbyehs.com/product/rf-blocking-canopies/

Testing RF Protection
The way to test RF Protection and RF Blocking fabric is by measuring RF next to a source or penetration point, and then putting the RF fabric/protection in between. The meter should show a big difference between the 2 measurements.
As seen in this video – https://youtu.be/hqr3n3rizhk
Take NATURELL RF Blocking Fabric for example.
According to the lab tests it blocks 99.97%(-35dB) or the RF coming right at it.
WIFI signal is considered “Excelent” at about -50dBm (see – https://eyenetworks.no/en/wifi-signal-strength/) .
A -35dB reduction will bring the WIFI signal to -85dBm, which means the WIFI will still work (but will be unstable), and the phone will still be able to connect to it.

What to do?
My recommendation is to stop thinking about “attacks” and continue your exposure reduction and handling EHS processes:
Exposure reduction – https://www.norad4u.com/emf-exposure-reduction/
Handling EHS – https://www.norad4u.com/ehs/handling-ehs/
Test the ability of the fabrics to block RF, using the ENV RD10, according to what is shown in the video.
In addition, continue to use the protection, if it makes you feel better (reduction of symptoms, and shortening recovery time).
If you haven’t done it yet, stop using wireless and cellular devices.
Thanks and best regards
