Why do I get Angina in large motor vehicles?

Afte my pacemaker was replaced, I am unable to drive or even ride in a rough vehicle such as a light truck or van.
I can only drive about in well sprung vehicles with a soft ride.  After driving a HiLux Toyota utility vehicle the angina pain was so severe I had a heart attack.  A neighbor drove me to church in his utility and I spent ages after with angina.

That's quite a heart event, and it's good you have posted it for others to consider.  What brand pacer was involved?

I'm glad you found the problem and sorted it. You should be a pacemaker consultant.
Not too long ago, I posted my opinion how electronic devices are all fallible but a few disagreed saying how pacemakers are put through intense standard checks. This just goes to prove how human designs don't think of every eventuality.
It shocks me to think how many people in different jobs could be affected by this.

I continued to have reflux - but there were no cardiac enzymes so it was assumed that I had Gord or severe reflux disease.  Anyway, I took a Hilux utility for a drive after posting this, and had a severe heart attack. I was rushed from Toowoomba Hospital to Prince Charles Hospital in Brisbane.  Despite massive medication, my heart would not slow down until I arrived at hospital.  I was put on a balloon pump. It took 3 weeks before I was able to leave hospital. After discharge, my only way of avoiding the severe angina (It wasn't reflux - my stomach was fine) was to avoid being conveyed in any sort of rough vehicle.
I wrote to the Princess Alexander Hospital and they called me in for a thorough checkup of my pacemaker.  It was regularly running my heart at 160 bpm.  The penny dropped!
There is a setting which detects when one is exercising. It senses vibration and increases the heart rate.  However, vehicle vibrations can fool it.  So if I got into a rough vehicle, my heart rate shot up.  If it stays up for long enough, I get a heart attack.  Solution - turn the setting off.  All cured.
Well, not quite.  My heart is severely damaged and runs at 25%.  I am now able to drive about in anything with 4 wheels.  My pacemaker nearly killed me.
I'm hoping this doesn't happen to others.

If one has a long history of heart disease, indigestion is probably due to Angina.  If your doctor prescribes anti-biotics make him give you a 'breath test'.  Insist on visual (camera) inspection of the reflux area.  Pacemaker induced tachycardia does not necessarily produce coronary enzymes.  Heart attacks always occur as a result of blockage of the coronary arteries - unless it's your pacemaker being naughty. Racing the heart at 160 bpm can also cause a coronary.

The leads were not replaced.  It's a cardioverter defibrillator (ICD)

Questions ---
I'm assuming you mean you replaced one pacer with another one.  What type/brand did you have before, and did you receive the same type/brand?  Also, I'm assuming that the leads weren't replaced.

What does your doctor say?  Also, have you contacted the pacer manufacturer?
