Atrioventricular conduction disease may occur in a range of conditions. If echocardiography suggests the presence of an infiltrative cardiomyopathy the diagnosis of amyloidosis may be confirmed by subcutaneous fat sampling from the site of pacemaker implantation. This technique requires no additional invasive procedure and confers no extra risk for the patient. Confirmation of amyloidosis provides important prognostic information and may allow specific treatment.
房室传导疾病可能在多种情况下发生。如果超声心动图提示存在浸润性心肌病，可通过从起搏器植入部位进行皮下脂肪采样来确诊淀粉样变性。该技术无需额外的侵入性操作，也不会给患者带来额外风险。淀粉样变性的确诊可提供重要的预后信息，并可能允许进行针对性治疗。
