At what current level does ventricular fibrillation occur?

• A. 50-100 mA
• B. 100-200 mA
• C. 200-300 mA
• D. 300-400 mA

Answer: (B)

Ventricular fibrillation, a critical condition where the heart's electrical activity becomes disorganized, can be induced by exposure to electrical currents. The current level at which ventricular fibrillation commonly occurs is in the range of 100 to 200 milliamperes (mA). At these levels, the heart is particularly sensitive to electrical interference, which can disrupt its normal rhythm and lead to chaotic contractions. Understanding the current threshold for ventricular fibrillation is crucial for professionals working with electrical systems, as it highlights the potential dangers of electrical shock. It emphasizes the importance of adhering to safety standards and using protective equipment when handling electrical components, especially in environments where contact with live currents is possible. The recognition of this critical current level underlines why proper safety protocols are essential for preventing accidental electrical injuries.
