A 34-year-old man reported heart fluttering and near syncope a few hours after marijuana smoking. In the emergency department, he was found to have a right bundle-branch-type ventricular tachycardia. The patient underwent a successful electric cardioversion. Coronary angiography showed no pericardial artery stenosis yet very slow coronary blood flow. Clinical tachycardia was also inducible in the electrophysiologic laboratory. After verapamil therapy and cessation of marijuana, his coronary flow normalized and ventricular tachycardia was no longer inducible in the electrophysiologic laboratory. Marijuana use might affect coronary microcirculation and cause ventricular tachycardia. Verapamil therapy and cessation of smoking might be curative.
一名34岁男性在吸食大麻数小时后出现心悸和接近晕厥的症状。在急诊科，他被发现患有右束支型室性心动过速。该患者成功接受了电复律治疗。冠状动脉造影显示没有心包动脉狭窄，但冠状动脉血流非常缓慢。在电生理实验室也可诱发出临床性心动过速。在维拉帕米治疗和停止吸食大麻后，他的冠状动脉血流恢复正常，在电生理实验室中也不再能诱发出室性心动过速。吸食大麻可能会影响冠状动脉微循环并导致室性心动过速。维拉帕米治疗和戒烟可能具有治愈作用。
