computer battery?

so last night my partner and I were watching some tv on my lap-top through netflix. And I had the box portion of my battery charger laying on my stomach near to my chest. After a little while I started feeling sick and faint and we quickly removed the charger because we thought that might be the problem. I started feeling better soon. I've had similar problems when using electric heating pads. I know everything says computers and heating pads are not supposed to interfere but is it still possible? Or am I just nuts? Thanks for your help :).

Just because it shouldn't doesn't mean it can't. If in doubt, keep 6" and don't take any chances! If it's something you can carry along easily, I'd take it to your next interrogation and see if you can duplicate it while hooked up to the machine.

POWER SUPPLY

A lot of battery chargers and mains adaptors have a switched mode power supply. This has a high frequency oscillator that increases the 50 cyles per second mains frequency to say 30000 cycles per second. Some harmonics can also be produced (multiples of the base frequency) This can in some circumstances interfere with your pacemaker. The reason why these power supplies have been developed is because the higher the frequency , the smaller and cheaper the expensive mains transformer can be. This saves a lot of money for the manufacturer. This type of power supply has become very common due to the availabilty of low cost very high power semiconductors that can also handle high voltages. I dont think enough consideration is being given to pacemaker patients by the electronic manufacturers. There could be more and more gadgets coming on the market which could effect us. We will have to keep a sharp lookout. Cheers Peter
