Car engine

I have a box truck with an engine in the cab like a van . Just has a cover over it. Is it safe to drive with then give alongside the dŕivers seat?


Engine in cab

I'd talk to your doctor.  My EP wouldn't be happy.  He doesn't even let me use a riding lawnmower because the operator is essentially sitting on the alternator.  He also told me not to work under the hood of the car (get that close) with the engine running.  I'm depedent so it's a bit more critical for me but I'd still advise you to get an answer from your cardiologist.

Don't lose any sleep over this

AgentX is correct to advise you to check with your Doc, but I would not lose any sleep over it unless everytime you drive it, you suddenly start to feel Bad (light-headed, dizzy, etc)! In this forum we don't give advice, but only suggestions based upon our experience. I have yet to find anything that affects it during the 36 years I've had my PM. 

If it does affect it, the most likely consequence is that it will set-off the magnet rate which is generally 80 bpm. I see you have a Medtronic device as I do. The manufacturer - Medtronic advises that if you feel bad when being too close to an electromagnetic field, simply back away from it. In your case, stop driving and shut-off the vehicle. These devices are shielded very well. so not to worry, but always check with you Doc when in doubt.

Here are a couple helpful links:

The issue isn't the magnet test mode.  It would take one hell of a magnet to trigger the test mode from two feet away.  Think auto junk yard.

The issue is the alternator inducing a current in the leads. This AC current (it doesn't take much) can trick the pacemaker into thinking that the heart is beating on its own when it isn't.  This is called "over-sensing".  It's not a matter of shielding, either, because it's magnetic interference, not electrical.

It's not usually a problem because most aren't dependent and the heart will go into an escape rhythm, which will cause one to feel ill - just move away.  Over-sensing can cause the pacemaker to stop working when it's needed.

It's not as much of a problem with the PM set for bipolar leads than it is with unipolar leads but not everyone's PM is set to bipolar pacing (my LV is set to unipolar).

The bottom line is that there are too my "ifs" and "maybes" not to buttonhole your doctor.  We can't answer that question here. There is a lot on the line.

To tell you the truth I never even give it a second thought. While growing up it never stopped me from doing anything and to this day my girlfriend or my kids need to remind me that I have one!
