Abstract

The purpose of this study was to determine if R-wave amplitude (Ramp) changes during a graded exercise test (GXT) would differentiate between middle-aged subjects with hypertension (HT) and normotension. Fifteen subjects with HT, 11 trained subjects with normotension (TR), and nine untrained subjects with normotension (UT) underwent a maximal GXT using the Bruce protocol. HT subjects exhibited higher systolic and diastolic blood pressure at rest and each stage of the GXT (P.05). Values for TR, HT, and UT subjects at peak exercise decreased to 17.1 mm, 11.5 mm, respectively. Ramp also failed to distinguish between HT subjects meeting ECG criteria for left ventricular hypertrophy (ECG-LVH) (n = 5) and HT subjects without ECG-LVH (n = 10). Comparisons between HT subjects with ECG-LVH and TR subjects with ECT-LVH (n = 8) also revealed no differences in Ramp response. In addition, Ramp response in HT-BB subjects did not differ from HT-NBB subjects or the other groups (P
