Abstract Background Cardiovascular disease is one of the leading causes of death globally with hypertension being a primary cause of premature death from this disease process. Individuals with a family history of cardiovascular disease and hypertension are at a greater risk for developing the same sequela. Autonomic cardiac control is important in the level of cardiac function. One intervention that is effective in improving cardiovascular function is heart rate variability biofeedback training. The purpose of our study was to determine the effectiveness of heart rate biofeedback training on HRV and blood pressure in individuals with a family history of cardiovascular disease. Methods Thirty-four participants (76.5% female, 22.7 ± 4.3 years) completed a baseline assessment and training using an established short-term HRV protocol followed by two weeks of at-home paced breathing employing a smartphone application. The participants were then reassessed in a biofeedback clinic. Results The participants physiological measures showed a significant increase in means between pre and post intervention of SDNN (t (32) = 2.177, p =.037) and TP, (t (32) = 2.327 p = .026). Correlation noted a medium effect on diastolic blood pressure and high frequency heart rate variability, F, r = .41, n =33, p < .05. A multiple regression with all predictor variables in the model found no significance with diastolic and systolic blood pressure. Conclusions The findings from this pilot study demonstrated that a two-week paced breathing intervention may assist in reducing heart rate and diastolic blood pressure while improving heart rate variability.

This study investigated changes in psychological and physiological markers during a weekend meditation workshop (N = 34). Psychological symptoms of anxiety, depression, posttraumatic stress disorder (PTSD) and happiness were assessed. Physiological markers included cortisol, salivary immunoglobulin A (SigA), heart rate variability (HRV), blood pressure (BP), and resting heart rate (RHR). On posttest, significant reductions were found in cortisol (−29%, P < .0001), RHR (−5%, P = .0281), and pain (−43%, P = .0022). Happiness increased significantly (+11%, P = .0159) while the increase in SigA was nonsignificant (+27%, P = .6964). Anxiety, depression, and PTSD all declined (−26%, P = .0159; −32%, P = .0197; −18%, P = .1533), though changes in PTSD did not reach statistical significance. No changes were found in BP, HRV, and heart coherence. Participants were assessed for psychological symptoms at 3-month follow-up, but the results were nonsignificant due to inadequate sample size (n = 17). EcoMeditation shows promise as a stress-reduction method.
