Jakub Lagan, Louise Cutts, Diane Barker, Peter Currie

Abstract

Background Hypothyroidism is a common endocrine disorder, which has a variety of effects on the cardiovascular system including decreased cardiac output, increased systemic vascular resistance, accelerated atherosclerosis and rhythm disturbances, such as sinus bradycardia, conduction defects or non-specific ST changes.1,2 Hypothyroidism can also cause prolongation of the QTc interval and ventricular arrhythmias.1 Case presentation A 76-year-old woman was admitted to our hospital with a collapse, and while in the emergency department she sustained a witnessed cardiac arrest secondary to torsades de pointes (TdP) (figure 1).

Abstract

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),
