=== Transcutaneous pacing ===
{{Main|Transcutaneous pacing}}
Transcutaneous pacing (TCP), also called external pacing, is recommended for the initial stabilization of hemodynamically significant [[bradycardia]]s of all types. The procedure is performed by placing two pacing pads on the patient's chest, either in the anterior/lateral position or the anterior/posterior position. The rescuer selects the pacing rate, and gradually increases the pacing current (measured in mA) until electrical capture (characterized by a wide [[QRS complex]] with a tall, broad [[T wave]] on the [[electrocardiogram|ECG]]) is achieved, with a corresponding pulse. Pacing artifact on the ECG and severe muscle twitching may make this determination difficult. External pacing should not be relied upon for an extended period of time. It is an emergency procedure that acts as a bridge until transvenous pacing or other therapies can be applied.<ref>{{Cite book |last1=Shah |first1=Maully |url=https://books.google.com/books?id=7hGdDgAAQBAJ&dq=External+pacing+should+not+be+relied+upon+for+an+extended+period+of+time.&pg=PA196 |title=Cardiac Pacing and Defibrillation in Pediatric and Congenital Heart Disease |last2=Rhodes |first2=Larry |last3=Kaltman |first3=Jonathan |year=2017 |publisher=John Wiley & Sons |isbn=978-0-470-67109-2 |language=en}}</ref>
