Diazepam poisoning is a common emergency situation, but propafenone poisoning is relatively rare. We reported a case of propafenone poisoning combined with diazepam. An 18‐year‐old female patient was admitted to our hospital with an overdose of oral propafenone and diazepam. The patient was treated with medication that proved to be useful, but the sinus rhythm could not be recovered, and cardiac arrest occurred. A bipolar temporary pacemaker and extracorporeal membrane oxygenation (ECMO) were installed. However, even with multiple electrode positions, effective capture could not be achieved. The patient eventually died. We should be alert to the possibility of co‐poisoning.

普罗帕酮和地西泮致死性自杀中毒一例

地西泮中毒是一种常见的紧急情况，但普罗帕酮中毒相对罕见。我们报告了一例普罗帕酮与地西泮合用中毒的病例。一名18岁女性患者因口服普罗帕酮和地西泮过量入院。患者接受了有效的药物治疗，但窦性心律无法恢复，心脏骤停。安装了双极临时起搏器和体外膜肺氧合（ECMO）。然而，即使有多个电极位置，也无法实现有效的捕获。病人最终死亡。我们应该警惕共同中毒的可能性。
