RETRACTED: Evaluating cardiac risks of TASER: An in-depth case study through probable current analysis

Area of Science:

• Forensic Science
• Cardiology
• Biomedical Engineering

Background:

• TASER devices are widely used for law enforcement.
• Concerns exist regarding the cardiac safety of TASER discharges.
• The first TASER-related fatality in South Korea prompted this investigation.

Observation:

• A case study involving a TASER-related fatality was analyzed.
• High-resolution waveform analysis and forensic examination of dart impact sites were performed.
• A human body impedance model of 500Ω was used, incorporating IEC 60479 standards.

Findings:

• Ventricular fibrillation (VF) risk was evaluated using Pratt et al.'s framework.
• Calculated VF risk reached up to 5%, contingent on dart impact location and current pathways.
• While not exceeding critical thresholds in the specific case, the VF risk was significant.

Implications:

• Dart impact location is a critical factor in TASER cardiac safety assessments.
• TASER discharges may contribute to fatal outcomes, emphasizing the need for safety protocols.
• This research informs broader understanding of TASER cardiac risks and safety recommendations.
