prehospital Transcutaneous cardiac Pacing for symptomatic bradycardia or bradyasystolic cardiac arrest a systematic review
Resuscitation, 2006Co-Authors: Jonathan Sherbino, Richard P Verbeek, Russell D Macdonald, Bruce Sawadsky, Andrew C Mcdonald, Laurie J MorrisonAbstract:Summary Background Advanced cardiac life support (ACLS) guidelines suggest Transcutaneous cardiac Pacing (TCP) for the treatment of symptomatic bradycardia (SB) and bradyasystolic cardiac arrest (BACA). Many EMS systems are extrapolating these guidelines and employing TCP in the prehospital setting. Our objective was to conduct a systematic review to determine the efficacy of prehospital TCP in the management of these two conditions. Methods MEDLINE (1966–2004), EMBase and Science Citation Index (1980–2004) were searched using: prehospital / emergency medical services ; external / Transcutaneous ; Pacing . Two reviewer teams blinded to the source and author conducted a hierarchical selection (title, abstract, article) and quality assessment using a validated scale. Kappa agreement at each level of review was measured. Data abstraction was done by consensus. Results Thirty-four articles were identified and seven selected (Kappa agreement; title: 0.85, abstract: 0.78, full article: 0.82). Article quality was poor in all trials. There were three case series (BACA, n =215), three unblinded randomised controlled trials (one BACA, two BACA+SB), and one subgroup (SB) analysis. In the case series of paced BACA patients, 0/215 survived to hospital discharge. In the BACA trials 16/509 (paced) versus14/497 (control) survived to discharge. In a subgroup of one SB trial 5/6 (paced) versus 1/7 (control) survived to discharge ( p =0.01). When a SB trial subgroup was combined with a case series 4/27 (paced) versus 0/24 (control) survived to discharge ( p =0.07). Conclusions In the prehospital setting, there is no evidence to support the use of TCP in bradyasystolic cardiac arrest. There is inadequate evidence to determine the efficacy of prehospital TCP in the treatment of symptomatic bradycardia.

acute myocardial infarction complicated by ventricular standstill terminated by thrombolysis and Transcutaneous Pacing
Resuscitation, 2007Co-Authors: Nick Castle, Crispin Porter, Beverley ThompsonAbstract:Although the overall need for emergency Pacing following AMI has reduced with the wide spread use of thrombolysis the availability of Transcutaneous Pacing offers an emergency non-invasive strategy to optimise circulation following CHB or ventricular standstill. Transcutaneous Pacing also facilitates the safe instigation of thrombolytic therapy to achieve reperfusion of the conduction system following AMI.

successful Transcutaneous Pacing in 2 severely hypothermic patients
Annals of Emergency Medicine, 2007Co-Authors: William G Heegaard, Douglas D BrunetteAbstract: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.
