  1. Microshock

    Microshock is a largely theoretical potential risk that is supposedly present for hospital patients with externally protruding intracardiac electrical conductors, such as external pacemaker electrodes, saline filled catheters, or weak or old heart tissue within the heart. There has never been a documented case of microshock. A U.S. Senate inquiry in the early 1970s, sparked by exaggerated reports of thousands of U.S hospital patients dying of microshock, heard expert testimony about the effect. A review of the evidence in the early 2000s found that not a single case had been reported in the 30 years since the Senate inquiry. Regular checks of the FDA's MAUDE database also show no evidence of this risk being manifest, before or since the review. Based on studies with dogs by Prof Leslie Geddes in the middle of last century, it is theorised that a current as low as 10 μA directly through the heart, may send a human patient directly into ventricular fibrillation. Of course, the exact outcome is dependent on the duration of the current, the exact position of contact, the frequency of current oscillation, and other factors. It is feared that such a small current may be introduced unwittingly, and unobserved, creating a very perilous situation for the patient. To guard against this slim theoretical possibility then, modern medical devices include a range of protective measures to limit current in cardiac-connected circuits to the assumed safe levels of below 10 μA . These measures include isolated patient connections, high impedance connections and current limiting circuits. Despite the in-built protections, and lack of observed incidents, microshock continues to be a concern to many practitioners of the fields of Biomedical and Clinical Engineering.
