“…10,22 T-wave oversensing has been reported as the leading cause of inappropriate shocks by the S-ICD in BrS patients. 23 Among our patients, S-ICD eligibility fluctuated between appropriate and inappropriate in some BrS patients because of variation in ECG morphology. Therefore, we recommend multiple evaluations of S-ICD appropriateness in BrS patients to ensure that ECG vector changes do not produce inappropriate shocks.…”

Background: Subcutaneous implantable cardioverter-defibrillators (S-ICD) could eliminate lead-associated complications. We assessed the prevalence of S-ICD ineligibility in conventional ICD recipients and compared it in patients with and without Brugada syndrome (BrS). Methods and Results:Consecutive patients with a transvenous ICD without an indication for antibradycardia pacing were assessed. A patient was considered eligible for S-ICD if the ECG satisfied the screening template, both supine and standing, in ≥1 lead. Among 130 patients (103 men, age 57±15 years), a total of 18 (13.8%) patients were ineligible. The BrS group (n=33) had a significantly higher prevalence of S-ICD screening failure as compared with the non-BrS group (P=0.003; 30% vs. 8.2%). In the BrS group, the body mass index (BMI) was significantly lower, and T/QRS amplitude in lead I was significantly higher in those who were ineligible than that in the patients who were eligible. Of the 10 BrS patients failing the screening, 4 became eligible in the right parasternal electrode position. Conclusions:Among current ICD patients, there was a high incidence of patients with BrS who were unsuitable for S-ICD based on the left parasternal screening test. Suitability screening of patients for S-ICDs should be conducted carefully in patients with BrS, particularly if the BMI is low. Right parasternal electrode positioning should also be tested in such BrS patients.

“…A previous registry revealed that the incidence of IAS with S-ICD was 13.1% at 3 years after implantation [3]. The most common cause of IAS was oversensing of the cardiac signal, such as TWOS, apart from heart rate increase due to supraventricular tachycardia in the shock zone [4]. A recent report showed that patients exhibiting an ST segment change during exercise, including patients with hypertrophic cardiomyopathy, were at risk for TWOS [5].…”

We report the case of a 51-year-old patient with Brugada syndrome (BrS) who experienced inappropriate shock due to T-wave oversensing (TWOS) during exercise when the optimal sensing vector was selected based on the automatic analysis by a subcutaneous implantable cardioverter-defibrillator (S-ICD). After selecting another vector during exercise testing, TWOS did not re-occur. Selection of appropriate sensing vector based on analyses under various conditions, including during exercise after S-ICD implantation, should be considered for patients with BrS.
