Why the study?

What is the incidence and what are the predictors of failed QRS-T-wave morphology screening for subcutaneous ICDs in ICD outpatients without pacing indications?

Population

230 consecutive ICD outpatients without an indication for cardiac pacing, mean age 57 ± 15 years, 75% male.

Design

Cross-sectional

Discussion

Member takes

Overview

Alerts clinicians to HCM and ECG predictors of S-ICD screening failure; leaves open prospective validation of refined eligibility criteria.

Structured PICO

What is the incidence and what are the predictors of failed QRS-T-wave morphology screening for subcutaneous ICDs in ICD outpatients without pacing indications?

Population

230 consecutive ICD outpatients without an indication for cardiac pacing, mean age 57 ± 15 years, 75% male.

Intervention

QRS-T morphology screening (TMS) using an ECG simulating the 3 sensing vectors of the S-ICD

Outcome

Failure of QRS-T morphology screening (TMS) for S-ICD suitabilitysurrogate

Approximately 7.4% of ICD outpatients without pacing indications fail S-ICD morphology screening, with hypertrophic cardiomyopathy and specific ECG characteristics being strong predictors of failure.
