Objective:

To report a case of refractory ventricular fibrillation induced by amiodarone in a patient with septic cardiomyopathy and QT interval prolongation, and to discuss the management approach, including a review of relevant literature.

Approach:

Key Findings:

• Moxifloxacin and amiodarone can induce refractory TdP and VF in patients with septic cardiomyopathy, highlighting the need for careful monitoring.
• Intravenous lidocaine combined with anisodamine successfully terminated the arrhythmias, suggesting a potential alternative treatment strategy.

Interpretation:

The case highlights the potential effectiveness of lidocaine and anisodamine in managing refractory arrhythmias in high-risk patients, indicating a need for further research into this treatment approach.

Limitations:

• The findings are based on a single case study, limiting generalizability.
• No control group or comparative analysis was conducted, and potential biases or confounding factors may affect the findings.

Conclusion:

Intravenous lidocaine and anisodamine may be a viable therapeutic option for refractory TdP and VF in patients with septic cardiomyopathy.
