Abstract. Blood Pressure (BP) and Heart Rate (HR) provide information on clinical condition along 24 h. Both signals present circadian changes due to sympathetic/parasympathetic control system that influence the relationship between them. Moreover, also the gender could modify this relation, acting on both control systems. Some studies, using office measurements examined the BP/HR relation, highlighting a direct association between the two variables, linked to suspected coronary heart disease. Nevertheless, till now such relation has not been studied yet using ambulatory technique that is known to lead to additional prognostic information about cardiovascular risks. In order to examine in a more accurate way this relation, in this work we evaluate the influence of gender on the BP/HR relationship by using hour-to-hour 24 h ambulatory measurements. Data coming from 122 female and 50 male normotensive subjects were recorded using a Holter Blood Pressure Monitor and the parameters of the linear regression fitting BP/HR were calculated. Results confirmed those obtained in previous studies using punctual office measures in males and underlined a significant relation between Diastolic BP and HR during each hour of the day in females; a different trend in the BP/HR relation between genders was found only during night-time. Moreover, the circadian rhythm of BP/HR is similar in both genders but with different values of HR and BP at different times of the day. Keywords: Blood pressure

1 Introduction Blood pressure (BP) and heart rate (HR) are physiological parameters related to cardiovascular system regulated by the autonomic nervous system [1]. In particular, HR provides significant prognostic information about cardiovascular morbidity and mortality both in healthy and in patients with cardiovascular risks, and BP is a powerful prognostic marker of target organ damage [2, 3]. Both measures are influenced by several internal factors, such as vasoactive hormones, hematologic and renal variables as well as by external factors including physical activity and emotional state. Along the 24 h increases and reductions of HR as well as of both Systolic BP (SBP) and © Springer Nature Switzerland AG 2021 T. Jarm et al.

Diastolic BP (DBP) are the result of stimulation and deactivation due to sympathetic/parasympathetic system. Mancia et al. [4], studying the circadian BP and HR rhythms, underlined that both signals presented higher values during daytime than during sleep. Moreover, several epidemiological studies examined if the relationship between the BP and HR was linear [5–7] and evaluated if this association was related with unknown or suspected coronary heart disease (CHD) [6].
