True statements about pacemakers include which of the following??

1) Electroshock therapy is unlikely to cause PM problems b/c the electrodes are far from the pacemaker

2) A magnet should not be used with programmable pacemakers because it may cause random reprogramming

3) To prevent PM malfunction d/t electrocautery, each of the following measures should be taken: use of a bipolar rather than unipolar form of electrocautery, if possible; use of short bursts of electrocautery; and placement of the ground plate as far from the PM generator as possible

4) Succinylcholine-induced fasciculations can inhibit some PMs & result in cardiac standstill

Any or all of the answers may be correct.:marchmellow:
