Hi Neethi;

If you've had a bypass but you're not on a pacemaker the MAGNETIC pulser will 
have no ill effect. 

If there's any doubt re:electrical stimulus from electrodes, you can always put 
the electrodes to your ankles as defined on Jaguar's site on usage of the 
various devices like zapper, Black Box, Beck Blood Electrifier (or silver 
pulser- SOTAs terminology)  www.excel.net/~jaguar .  

With the tachycardia you're probably on medication, so do the treatments before 
you take any meds. This also is covered in the Jaguar site, as is the FULL 
4-part electromedical treatment program.

ciao

    <snip>is it safe for a heart bypass operated patient to use the zapper  or 
the simple pulser?
    how about someone with tachycardia?
