← ScienceWhich outcome occurs when a cardiac magnetic stimulator's coils rapidly discharge?
A)Tissue depolarization exceeding cell threshold✓
B)Increased diffusion across cellular membranes
C)Elevated ATP production inhibits contraction
D)Reduced gap junction resistance accelerates repolarization
💡 Explanation
Rapid coil discharge induces a strong, pulsed magnetic field disrupting ion flow; Voltage-gated channels then cause tissue depolarization above the threshold because changes Faraday's Law of electromagnetic induction occur rapidly; therefore the correct answer is A, rather than other answers which would involve different biological and electrical events.
