If you do not have ventricular capture ensure the pacing box is turned on and that all connections are correct. Modern external pacemakers use longer pulse durations and larger electrodes than the early models did. The same goes for individual services or products.
A rhythm strip showing failure to capture in the first four pacing stimuli that did not produce any pulse. 1999 Apr. Use of this blog and its associated media does not constitute the establishment of a physician-patient relationship. It is accomplished by delivering pulses of electric current through the patient's chest, stimulating the heart to contract. The patient appeared to have palpable pulses; however, the rhythm contractions of the patients body from the pacer shocks made this assessment difficult. A, Skeletal muscle stimulation is clearly apparent for the initial 8 s of transcutaneous pacing at 200 mA, after which pacing is turned off. Bernstein AD, Daubert JC, Fletcher RD, Hayes DL, Luderitz B, Reynolds DW, Schoenfeld MH, Sutton R. The revised NASPE/BPEG generic code for antibradycardia, adaptive-rate, and multisite pacing.
