To determine whether ventricular late potentials, detected by means of signal-averaged electrocardiography (SAECG), were associated with sudden death in Doberman Pinschers with occult cardiomyopathy.
Case series.
39 Doberman Pinschers with occult cardiomyopathy.
Cardiomyopathy was diagnosed by means of serial echocardiography and ambulatory electrocardiography; SAECG was performed 1 or more times for each dog.
12 dogs died suddenly; the other 27 died after developing overt clinical signs of congestive heart failure. Results of SAECG were associated with outcome, and dogs in which ventricular late potentials were detected were more likely to die suddenly. however, 5 dogs for which results of SAECG were normal (n = 2) or equivocal (3) also died suddenly.
Results suggest that SAECG may be useful in predicting whether Doberman Pinschers with occult cardiomyopathy, confirmed on the basis of results of echocardiography, are at risk of dying suddenly. However, the possibility of sudden death cannot be ruled out simply because results of SAECG are normal.
通过信号平均心电图（SAECG）检测，确定隐性心肌病杜宾犬的心室晚电位是否与猝死相关。
病例系列。
39只患有隐性心肌病的杜宾犬。
通过连续超声心动图和动态心电图诊断心肌病；对每只犬进行1次或多次SAECG检查。
12只犬猝死；另外27只在出现明显的充血性心力衰竭临床症状后死亡。SAECG结果与结局相关，检测到心室晚电位的犬更可能猝死。然而，5只SAECG结果正常（n = 2）或不明确（3只）的犬也猝死。
结果表明，SAECG可能有助于预测根据超声心动图结果确诊的隐性心肌病杜宾犬是否有猝死风险。然而，不能仅仅因为SAECG结果正常就排除猝死的可能性。
