(a) Original tracing for a single hypertensive SHR showing pulsatile ABP and MAP responses (telemetry) produced during bilateral RF-ABL of the renal arteries under sodium methohexital anesthesia and 2-months later while conscious. (b) Original BP tracing for a single SHR during the RF-ABL procedure under isoflurane anesthesia. (c) Group data illustrating the change in MAP measured 10 minutes following completion of RF-ABL or Sham-ABL of the second renal artery conducted under isoflurane anesthesia. Sham, n = 6; RF-ABL, n = 9. Values are means ± SE. *P < 0.05, compared with Sham-ABL; ^tP < 0.05, compared with baseline MAP. Abbreviations: ABP, arterial blood pressure; MAP, mean arterial pressure; RF-ABL, radiofrequency ablation of the renal arteries; SHR, spontaneously hypertensive rats.
