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). In skilled hands, the semifloating transvenous catheter is successfully placed under electrocardiographic (ECG) guidance in 80% of patients.1 The technique can be performed in less than 20 minutes in 72% of patients and in less than 5 minutes in 30% ( Videos 15.1 - 15.3 ).

When capture occurred, each pacing artifact was followed by a QRS complex (albeit bizarrely shaped) and pulse. Transcutaneous pacing (TCP) is a difficult skill that is often performed incorrectly. Good pacing pad to skin attachment and close proximity of the pads to the heart are important factors in reducing the pacing threshold, which is the most important factor predicting discomfort and reliability of the captures. hb```"uVxa !&00a` 30*31(5Xp-`Jb&[3O M2UrPf!,+4h=_A&- _6 [QxMD MEDLINE Link].

Ramin Assadi, MD is a member of the following medical societies: American College of Cardiology, American College of Physicians, American Medical Association, Society for Cardiovascular Angiography and InterventionsDisclosure: Nothing to disclose. 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). Transcutaneous Cardiac Pacing. 84(3 Pt 1):395-400. Transcutaneous Cardiac Pacing Medication - Medscape [Full Text]. TCP is contraindicated in severe hypothermia and is not recommended for asystole. Ettin D, Cook T. Using ultrasound to determine external pacer capture. Alternatively, the positive electrode can be placed anteriorly on the right upper part of the chest (see the image below). [Full Text]. Europace 2013; 15:1287. Pacing spikes are visible with what appear to be large, corresponding QRS complexes. Implantation of leadless pacemakers via inferior vena cava filters is feasible and safe: Insights from a multicenter experience. The transcutaneous pacer is set for 70 PPM at 50 mA. IO access is obtained in right proximal tibia. If capture occurs, slowly decrease output until capture is lost (threshold) then add 2 mA or 10% more than the threshold as a safety margin. Springer, Cham. For example, if the device captures at 1 mA, then the pacer should be set at 2-3 mA for adequate safety margin.
