  • a flexible catheter for insertion into the esophagus of said patient, said catheter having a proximal end and a distal end, said catheter comprising a hollow flexible exterior tube and a hollow flexible interior tube inserted into said exterior tube;

    first and second pacing electrodes coupled to said catheter, said first pacing electrode being located closer to the distal end of said catheter than said second pacing electrode;

    a pacing generator for generating electrical pulses used to pace the patient'"'"'s heart, wherein each of said electrodes is of sufficient surface area to prevent injuring said patient'"'"'s esophagus during continuous emergency pacing; and

    a pair of electrical conductors located between said exterior tube and said interior tube, one of said pair being connected between said first pacing electrode and said pacing generator for conducting said pulses to said first pacing electrode and the other of said pair being connected between said second pacing electrode and said pacing generator for conducting said electrical energy between said second pacing electrode and said pacing generator.
