Background: The subcutaneous implantable cardioverter-defibrillator (S-ICD) is an alternative to traditional ICDs. The PRAETORIAN score, based on chest radiographs, has been validated to predict the probability of successful S-ICD defibrillation testing by assessing factors like fat thickness between the coil and sternum and generator placement.

Objective: This study evaluated the correlation between the PRAETORIAN score and clinical characteristics, as well as implantation variables.

Article Synopsis
  • - The study investigates the relationship between obesity and heart failure in patients using a wearable cardioverter-defibrillator, finding that those with a BMI over 30 kg/m^2 had better left ventricular ejection fraction improvements than patients with lower BMIs.
  • - Despite similar adherence to using the defibrillator and rates of arrhythmic events across different BMI groups, patients with a BMI over 30 experienced significantly lower rehospitalization rates for cardiovascular issues compared to those with a BMI between 25-30.
  • - At a two-year follow-up, mortality rates were notably lower for the highest BMI group (5.9%) compared to those with a BMI under 25 (7.5%), highlighting a potential 'ob

Article Synopsis
  • * The review discusses how daily rhythms affect arrhythmia events and emphasizes the need for a comprehensive approach in diagnosing and treating these issues, especially considering factors like sleep disorders and comorbidities.
  • * Effective treatments for nocturnal arrhythmias may involve adjusting medication timing, addressing underlying health conditions like obesity and sleep apnea, and utilizing specialized therapies, which can reduce severe heart issues and the need for invasive procedures.

Following a non-ST-elevation myocardial infarction (MI), a 68-year-old hypertensive, severely obese woman with 45% left ventricular ejection fraction underwent an implantable cardiac monitor (ICM) insertion. After 8 months, the ICM remotely transmitted multiple non-sustained ventricular tachycardia episodes. Symptomatic during these events, the patient underwent an invasive electrophysiologic stimulation, which induced ventricular arrhythmia.
