“…Bohm, Trilica, and Veljacikova (1967) have reported that older patients with chronic hypertension produced more slow waves than younger patients with less advanced hypertension ; this finding is consistent with our data. However, the relationships between EEG patterns and cardiovascular function may be complex; while pulse rate was related inversely to theta in the present study, results in the opposite direction also have been reported (Darrow, Pathman, &Iironenberg, 1946), andBeatty andIiornfeld (1972) found that training to increase alpha and beta did not affect either pulse rate or blood pressure. Williams and Cartwright (1969) also have reported relationships between EEG variables and blood pressure variability.…”
