1. A method of locating the coronary sinus of a heart, comprising the steps of:

  • endovascularly introducing a catheter into a right atrium of the heart;

    sensing a characteristic of blood at the distal end of the catheter;

    qualitatively correlating the sensed characteristic of the blood at the distal end of the catheter with a characteristic of blood of the coronary sinus; and

    steering the catheter toward a region in which the sensed characteristic is qualitatively correlated with the blood of the coronary sinus.
