A member asked:

Can you still have a heart attack or go into cardiac arrest if you have a pacemaker?

Yes: Both of these problems are due to issues not addressed by the pacemaker. A heart attack is generally due to a blockage and a heart artery, and cardiac arrest is usually due to an exceedingly fast heart rate where the pacemaker only fixes slow heart rates. A defibrillator is the device of choice to treat cardiac arrest.

Pacemaker: Pacemakers are intended to address cardiac rhythm primarily if to slow. Not protective from ischemia so yes heart attack still possible and arrest possible. Acid can help with arrest if indicated but not prevention of ischemia.
