    Electrical micro-shocks can interfere with heart rhythm and cause ventricular fibrillation. Monitoring central venous pressure poses a risk of electrical micro-shock, requiring greater clinical consideration.

    Area of Science:

    • Medical Devices
    • Cardiovascular Physiology
    • Patient Safety

    Background:

    • Electrical micro-shock is a known risk for patients undergoing cardiac catheterization or connected to electronic monitoring equipment.
    • Central venous pressure monitoring is a common procedure during surgeries.

    Purpose of the Study:

    • To investigate the risk of electrical micro-shock during central venous pressure monitoring.
    • To assess the potential for cardiac rhythm interference and ventricular fibrillation.

    Main Methods:

    • Studies were conducted on dogs catheterized for central venous pressure measurement.
    • Catheters were advanced into the right ventricle for monitoring.

    Main Results:

    • Electrical currents below 500 micro-amperes interfered with heart rhythm.

  • Ventricular fibrillation developed in some dogs at these low current levels.

    • Conclusions:

    • Monitoring central venous pressure carries a risk of electrical micro-shock.
    • Increased attention to electrical safety is warranted for patients undergoing central venous pressure measurement.
