Key result
Greater height (180 vs 174 cm, p=0.01) and longer QRS duration (119 vs 100 ms, p=0.0003) were significant predictors of preimplantation screening failure, which occurred in 9.8% of S-ICD candidates.
Why the study?
To evaluate key preimplantation screening parameters to optimize patient selection for subcutaneous implantable cardioverter-defibrillator placement.
What are the clinical and anthropometric predictors of preimplantation screening failure in candidates for subcutaneous implantable cardioverter-defibrillators?
Observational (n=91)
What are the clinical and anthropometric predictors of preimplantation screening failure in candidates for subcutaneous implantable cardioverter-defibrillators?
Greater height and prolonged QRS duration are significant predictors of preimplantation screening failure for subcutaneous implantable cardioverter-defibrillators.
May inform S-ICD candidate selection to reduce screening failures; leaves open prospective validation before clinical adoption.

Верещагина et al. (2021) conducted an observational in Indications for subcutaneous implantable cardioverter-defibrillator (S-ICD) implantation (n=91). Anthropometric and ECG characteristics was evaluated on Negative result of preimplantation screening. Greater height (180 vs 174 cm, p=0.01) and longer QRS duration (119 vs 100 ms, p=0.0003) were significant predictors of preimplantation screening failure, which occurred in 9.8% of S-ICD candidates.
