Successful transcutaneous pacing in 2 severely hypothermic patients.

The clinical condition of profound hypothermia is well described in the medical literature. There have been many case reports and studies describing successful aspects of caring for this problem. Significant bradycardia is a known pathophysiologic consequence of profound hypothermia. Transcutaneous pacing for this condition is not a routine or recommended practice in the literature. This case report details 2 patients with profound hypothermia and resultant bradycardia with hypotension. In both cases, transcutaneous pacing was successfully applied and used as part of the resuscitation. In both cases, transcutaneous pacing was required to maintain an adequate blood pressure so that continuous arteriovenous rewarming could be used during the resuscitation. Both cases had successful outcomes, and the rewarming process was greatly assisted by the pacing procedure.
