Increasing mA beyond initial electrical capture threshold

Question #: 480


In the procedure of TCP, upon electrical capture do you add 10 milli amps even if you have mechanical capture with signs of perfusion


During transcutaneous pacing procedure, upon electrical and mechanical capture, it is recommended to increase the milliamps (mA) 10% higher than the threshold of initial electrical capture as a safety margin (usually 5-10 mA). When using external transcutaneous pacing, the conduction can fade with time; the pacer can stop working. Increasing energy can assist mitigating that risk. Transcutaneous pacing can be uncomfortable for a patient. Sedation and analgesia can be considered when consulting a Base Hospital Physician to tailor the management plan to the patient.
