We retrospectively evaluated our ICD database between September 2006 and October 2007 to determine baseline patient/procedure characteristics and details of defibrillation threshold assessment during implant. All patients underwent at least two defibrillation safety margin (DSM) tests (≥10 J below the maximum output of the device). Logistic regression analysis was performed to identify factors predicting two successful consecutive DSM tests (with ≥10 J safety margin). A total of 264 procedures were performed (mean age ± standard error: 65.6 ± 0.8 years); 258 (97.7%) patients had successful first DSM test (with ≥10 J safety margin),
