Just as Yan Ye and the forensic expert fell into deep thought, An Hao suddenly said, "You mentioned currents above 10 amps. Currents ranging from 18 to 22 milliamps caused heart fibrillation, or perhaps the 22 milliamp current caused cardiac arrest, which then led to a massive heart attack."
After re-examining the body's condition, Yan Ye also confirmed An Hao's assertion, "I think there's no major issue. This should be a death caused by electrocution."
The forensic expert agreed with this statement.
That afternoon, the autopsy results were relayed to the patient's family, and thereafter the police began their investigation. Three days later, the investigative results were out—the patient indeed died from electrocution.
The patient had accidentally touched an extremely fine copper wire of an electric fan on the table, which was exposed. Although it only caused a small burn on the skin, it unexpectedly triggered atrial fibrillation.
