These heart contractions did not correspond with the surrounding thoracic muscle contractions generated by the pacer. Share cases and questions with Physicians on Medscape consult. Note that pacing temporary wires at unnecessarily high outputs may lead to premature carbonisation of the leads and degradation of wire function. Castle N, Porter C, Thompson B. 22(4 Pt 1):588-93. He may require TCP until his conduction system recovers or until he receives a transvenous pacemaker. [PMID:8558949], 2. The indications can be split into two broad categories: emergency (commonly with acute myocardial infarction (MI)) and . Usual practice is to have a pacing safety margin of at least 2 times (or 3 times if the patient has an unstable escape rhythm) - if the pacing threshold is 3, set at 7 (or 10). [QxMD MEDLINE Link].
