The invention discloses a cardiac impulse electric field ablation catheter. The cardiac impulse electric field ablation catheter comprises an annular distal end, wherein the annular distal end comprises an arc-shaped end pipe body, annular electrodes in an odd number are distributed on the end pipe body at equal intervals, and the electrodes are connected to a first connector arranged on a handlethrough wires penetrating through the pipe body; and an end hard pipe is connected with the end pipe body, a supporting member penetrates through the end pipe body and the end hard pipe, two magneticpositioning sensors are arranged in the end pipe body and fixed on the supporting member, and a magnetic positioning sensor is arranged in the end hard pipe. External equipment transmits high voltagepulses and electrical signals to the catheter to achieve ablation, and the catheter also transmits feedback information to the external equipment for positioning, modeling and the like. High-voltage pulse energy can be concentr
