OBJECTIVE: To evaluate the acute effect of physiotherapy (deep breathing exercises and walking) on heart rate variability in patients hospitalised with chronic heart failure (CHF). DESIGN: Ten males with CHF (57â±â7 years) and 10 healthy controls (59â±â9 years) were included. Heart rate and RR intervals were recorded in the following conditions: supine, seated, during deep breathing exercises and during and after walking. Heart rate variability was analysed by linear and non-linear methods (α2, Mean HR, rMSSD, SDNN and ApEn). RESULTS: Patients presented significantly lower SDNN (12.4â±â4 versus 26â±â8 ms), rMSSD (18.2â±â16.2 versus 25â±â19.5 ms) and ApEn (9.9â±â10 versus 16.68â±â22.6) during the walking compared to controls (pâ<â0.05). In addition, mean HR was significantly higher during and after walking for patients with CHF compared to controls (103â±â8 versus 80â±â2 bpm and 90â±â9 versus 68â±â2 bpm, respectively). Patients with CHF demonstrated a significant reduction of α2 during deep breathing (0.78â±â0.1) when compared to the seated position (1.08â±â0.1) and walking (1.15â±â0.2, pâ<â0.05). Additionally, rMSSD index increased during deep breathing when compared to walking in both groups. CONCLUSION: Deep breathing exercises and walking are safe and promote beneficial effects on heart rate variability in patients hospitalised for CHF.
