We present new closed form expressions for probability distribution function (PDF) and cumulative distribution function (CDF) of end-to-end signal to noise ratio (SNR) per branch in terms of Meijer's G function. From these

[1] The development of the Boston Scientific subcutaneous ICD (S-ICD) promoted the benefit of significantly reduced post-implant complication rates. [4] We present the first reported case of a S-ICD electrode failure secondary to partial fracture as a result of mechanical trauma.

However, the contemporary prevalence, reasons, and predictors of 30-day readmissions are not well known. Hospitalizations for a primary diagnosis of AMI complicated by cardiogenic shock, and discharged alive, were identified in the 2013 and 2014 Nationwide Readmissions Databases. Prevalence and reasons for 30-day unplanned readmissions were investigated. A hierarchical logistic regression model was used to identify independent predictors of 30-day readmissions. Among 1Â 116Â 933 patient hospitalizations with AMI, 39Â 807 (3.6%) had cardiogenic shock and were discharged alive. Their 30-day readmission rate was 18.6%, with a median time for readmission 10Â days post discharge. Predictors of readmission included: non-ST-segment elevation myocardial infarction, female sex, low-income status, nonpri...
