Abstract

This study sought to examine the use of the subcutaneous implantable cardioverter-defibrillator (S-ICD) in teenagers and young adults. The S-ICD is an important advance in device therapy for the prevention of sudden cardiac death. Although guidelines recommend S-ICD use, long-term data are still limited, especially in subgroups. Therefore, this study analyzed teenagers and young adults <26 years of age with S-ICD in our large single-center S-ICD registry. Between July 2010 and December 2016, 147 S-ICD systems were inserted at our institution. Thirty-one patients were included in the study; 13 were teenagers (<20 years of age), and 18 were young adults (20 to 26 years of age). The patients were compared with an age-matched control group with transvenous ICDs. Primary prevention of sudden cardiac death was the indication in 13 patients (41.9%). Ventricular arrhythmias were adequately terminated in 8 patients (25.8%). In 5 patients (16.1%), oversensing resulting in at least 1 inappropriate shock was observed. All inappropriate shocks occurred in teenagers. Younger age was an independent predictor of inappropriate shocks in S-ICD (hazard ratio: 0.56; 95% confidence interval: 0.34 to 0.92; p < 0.05). No ineffective shocks were obser...Continue Reading

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.
