A temporary balloon-type electrode for insertion and temporary fixation in a blood vessel of a heart, for determining a suitable place therein for a subsequently inserted and fixed permanent electrode, has a catheter and an inflatable and deflatable balloon member disposed at a distal end portion of the catheter. The balloon member has at least one radially expandable hollow body. At least one electrode surface contact member is disposed at a peripheral portion of the hollow body, and flow passages are provided for allowing a blood flow to pass the balloon member when inflated. The temporary balloon-type electrode is particularly suited for use in coronary sinus and peripheral coronary veins of the heart.
