Chronobiological Analysis of Blood Pressure in a Patient with Atrial Fibrillation at the Development of Heart Failure and Its Therapeutic and Surgical Treatment

Figure 2

Daily profiles of systolic blood pressure (SBP), and heart rate (HR) before heart failure and during its treatment. ((a)–(r)): Subsequent stages of development. Upper row: SBP; lower row: HR. Abscissa: clock time; ordinates: variable’s value (SBP: mmHg; HR: beats/min). Black dots: separate records, Black curve: approximation of the process, Green lines: 95% confidence limits (CL) of approximation, blue lines: 95%CL of records population, Horizontal brown lines: middle night-time and middle day-time variable levels and Vertical red lines: positions of top and statistically significant elevations during the 24-hour span (99%CL-s). Vertical violet lines: positions of bottom and statistically significant decreases during the 24-hour span and their (99%CL-s).
