1、Deferred DFT testing at the time of cardiac resynchronization therapy is associated with poor long term outcome,Grace Lin, MD, Peter A. Brady, MD, David L. Hayes, MD Mayo Clinic, Rochester, MN USA,Background,Defibrillation threshold (DFT) testing is commonly performed at the time of ICD implantation
2、 In some cases DFT testing may not be performed, or deferred to a later date Impact of no or deferred DFT testing on outcome is unknown,Background,No or deferred DFT testing: Inadequate anticoagulation Hemodynamic instability Physician discretion Likelihood of no or deferred DFT testing may be highe
3、r in patients undergoing cardiac resynchronization therapy (CRT),Background,Prevalence and reasons of no or deferred DFT testing in patients undergoing CRT are unknown Outcome of CRT patients who undergo DFT testing vs. those who do not is unknown,Methods,All CRT-D implants from 1999-2004 at Mayo Cl
4、inic Review of Clinical record Operative note ICD database Clinical follow up via questionnaire,Methods,DFT+ DFT testing at implant DFT- DFT testing not at implant Delayed DFT Subsequent DFT testing DFT- never No subsequent DFT testing,Definitions,Results,Device Implants 1999-2004,Results,Baseline C
