Why the study?

Does repetitive intraoperative defibrillation threshold testing cause cumulative adverse consequences in patients undergoing ICD implantation?

Population

84 patients undergoing initial implantation procedure for a cardioverter defibrillator (ICD)

Implication

Repetitive intraoperative defibrillation threshold testing appears generally safe in stable patients, as adverse consequences of multiple shocks do not appear to be cumulative.

Key Points

To assess the safety of multiple defibrillation tests during the implantation of cardioverter defibrillators.
Analyzed intraoperative defibrillation threshold tests in 84 patients.
Mean of 5.27 defibrillation trials and up to 50 shocks per procedure were recorded.
Monitored clinical status, including heart rate and blood pressure, during DFT testing.
Mean joules received during testing was 275.0.
Two complications occurred, including one electromechanical dissociation and one myocardial infarction.
No cumulative adverse effects noted with extensive testing in stable patients.

Structured PICO

Does repetitive intraoperative defibrillation threshold testing cause cumulative adverse consequences in patients undergoing ICD implantation?

Population

84 patients undergoing initial implantation procedure for a cardioverter defibrillator (ICD)

Intervention

Repetitive intraoperative defibrillation threshold testing (DFTT)

Outcome

Complications related directly to the intraoperative defibrillation threshold tests (DFTT)safety

Repetitive intraoperative defibrillation threshold testing appears generally safe in stable patients, as adverse consequences of multiple shocks do not appear to be cumulative.
