The assertion that the human body can withstand a higher current for a shorter duration while avoiding heart fibrillation is supported by the principles of electrical safety and the physiology of the heart. In general, the threshold for causing fibrillation in the heart can indeed be influenced by the duration of current exposure.

When current flows through the body, it interacts with the heart's electrical signals. A brief exposure to a high current may not be sufficient to disrupt these signals, thereby avoiding fibrillation. This phenomenon is often described by the concept of the "let-go" current, which is the maximum current that can be tolerated without muscle contractions preventing a person from releasing a source of electricity.

It's also important to consider individual variations, such as health, condition of the heart, and the path the current takes through the body; these factors can greatly influence a person's risk for fibrillation. However, the key takeaway is that higher currents, for shorter durations, may not necessarily lead to heart fibrillation under certain conditions. This understanding reinforces the importance of electrical safety measures and awareness of the body's limits in dealing with electrical currents.
