REVIEW

Evaluation of body weight as a predictive factor for transvenous ventricular defibrillation characteristics

J.R Paisey*, T Betts, S Allen, J.M Morgan and P.R Roberts

Wessex Cardiothoracic Centre Southampton, UK

AIMS: To investigate the correlation between body weight and defibrillation threshold (DFT) for transvenous lead systems using a porcine model.

METHODS AND RESULTS: Twenty-eight pigs were anaesthetised and DFTs assessed in single and dual coil configurations using a four-reversal binary search method. DFT was correlated with body weight in the RV -> Can and RV -> SVC + Can configurations. A Pearson correlation coefficient and a two-sided p-value were calculated. A positive correlation exists between body weight and DFT in RV -> Can (r=0.66, p<0.000) and RV -> SVC + Can (r=0.44, p=0.018).

CONCLUSION: There is a significant correlation between body weight and DFT in swine. This tends to be greater in the two-electrode than in the three-electrode configuration. With these and previous human observations, one may predict a higher DFT in heavy individuals and make appropriate procedural adjustments.

Key Words: implantable cardioverter defibrillator, defibrillation threshold, ventricular arrhythmia, fibrillation, body weight
