In an effort to keep control of the raging Hulk inside him, Bruce Banner (Edward Norton) used a heart rate monitor to stay aware of his body and prevent his metamorphosis into the jade giant. Production noted this as one of the monitors used by actor Edward Norton. It is given to him by Betty Ross (Liv Tyler) after they meet again in the hotel after Banner looses his previous monitor in the "Brazil incident".
