Table 1 Table of lead dislodgement and lead penetration findings

From: A retrospective review of 146 active and passive fixation bradycardia lead implantations in 74 dogs undergoing pacemaker implantation in a research setting of short term duration

  1. aAll dislodgements were passive fixation (preformed J in the RA; straight passive in RV)
  2. bA P value < 0.05 was considered significant; however, the study was not powered for this endpoint
