Chronic exposure to silica is a recognized health hazard. Manifestations of pulmonary and extrapulmonary silicosis are well described. Secondary pulmonary arterial hypertension and pericardial involvement are described, but myocardial involvement has not been reported. In this case of newly diagnosed pulmonary silicosis, ventricular tachycardia results are shown from pathological involvement of ventricular myocardium. ().
长期接触二氧化硅是一种公认的健康危害。肺硅沉着病和肺外硅沉着病的表现已有详细描述。继发性肺动脉高压和心包受累也有相关描述，但心肌受累尚未见报道。在这个新诊断的肺硅沉着病病例中，显示室性心动过速是由心室心肌的病理累及所致。（）
