Methods A new transcatheter arterial pacing catheter was developed by using permanent endocardial catheter technology and materials, and was used in the rescue of animal experiments and fatal bradyarrhythmia patients. Results The pacing electrode possesses good maneuverability, short effective pacing time, ideal pacing parameters, good tensile and flexibility, few complications such as electrode rupture. Conclusion The preliminary results suggest that the new pacing lead is safe, effective, inexpensive and suitable for emergency bedside cardiac pacing
