Hypothesis
Understanding the predictors of appropriate ICD therapy could help to better identify candidates for ICD implantation.
Conclusion
QRS width could be used as an additional simple risk stratifier beyond EF to identify potential candidates who would benefit more from ICD implantation.
Supporting Evidence
- 54 patients (33%) received appropriate ICD therapy during the follow-up.
- Male gender and DCM were correlated with increased likelihood of appropriate ICD therapy.
- QRS width > 100 ms was associated with a higher probability of appropriate ICD therapy.
Takeaway
This study looked at patients with heart problems who got a special device to help with their heartbeats. It found that certain heart measurements can help doctors decide who might need this device.
Methodology
The study included 162 patients with ICD, collecting clinical, electrocardiographic, and ICD data over a mean follow-up of 15 months.
Limitations
The study was retrospective and non-randomized, which may affect the conclusions.
Participant Demographics
Mean age was 58.2 ± 13.5 years, with 123 men and 39 women.
