Claim:
1. A method for identifying patients responsive to renal ablation for treatment of disease caused by systemic renal nerve hyperactivity, comprising the steps of: a. introducing a catheter into the lumen of a renal artery of a patient such that a tip of said catheter contacts a site on the inner renal artery wall; b. measuring one or more physiological parameters to obtain baseline measurements before introducing an electrical current to the site, said physiological parameters are selected from the group consisting of systolic blood pressure, diastolic blood pressure, mean arterial pressure, and heart rate; c. applying electrical stimulation by introducing said electrical current to the site via the catheter, wherein said electrical current is controlled to be sufficient to elicit an increase in said one or more physiological parameters when there is an underlying nerve at the site; d. measuring said one or more physiological parameters at a specific time interval after each electrical stimulation, wherein an increase of said physiological parameters over the baseline measurements after said electrical stimulation would indicate that said patient is responsive to renal ablation; and e. performing renal ablation on said patient.
