Remote access to the heart? Absolutely—tons of ways, from wireless implants pulling data to waves and beams influencing cells directly. Monitoring is everyday stuff; tweaking rhythms is in trials for healing but could flip to harm. If this tech's out there, demand oversight—transparency from researchers, regs on dual-use tools. Protect your health with basics: Check your heart regularly, limit strong field exposure. Stay sharp; this isn't paranoia, it's preparation.
