The major role of cardiopulmonary resuscitation is to provide some blood flow to both the myocardium and central nervous system to allow for successful defibrillation and resuscitation, and to preserve long-term organ function. The ABC of resuscitation begins with basic life support and the establishment of an adequate airway (A), breathing (B) and circulation (C). Pacing can often be life saving, especially in situations where bradycardia preceded the cardiac arrest or where bradycardia is associated with haemodynamic intolerance following successful resuscitation. The resuscitation trolley should always be present and venous access available. Temporary venous pacemakers should be checked at least once daily for pacing threshold, evidence of infections around venous access sites, integrity of connections, and battery status of the external generator. Transcutaneous pacing can be easily applied, requires minimum training and avoids the risks of central venous cannulation.
