Abstract
Interference spikes were noted on the electrocardiogram of a patient with an implanted demand pacemaker. Runaway malfunction was suspected and the generator replaced. Subsequent investigation showec that the interference originated from fasciculation in the left leg caused by underlying neuromuscular disease. Skeletal muscle potentials can produce an electrocardiographic appearance closely resembling 'runaway' pacemaker. Such abnormalities should prompt a search for occult neuromuscular disease.
摘要
在一名植入按需起搏器的患者心电图上发现了干扰尖峰。怀疑出现失控故障并更换了发生器。随后的调查表明，干扰源自潜在神经肌肉疾病引起的左腿肌束震颤。骨骼肌电位可产生与“失控”起搏器极为相似的心电图表现。此类异常情况应促使医生寻找隐匿性神经肌肉疾病。
