“…Whereas children generally prefer to sleep in the prone position, adults spend more time sleeping in the lateral position, with RLDSP preferred more than the LLDSP due to age‐related alterations in musculoskeletal structures and/or cardiovascular functions . The people tend to sleep for longer periods on their right side, apparently to avoid disturbance by the enlarged apical heartbeat or further hemodynamic or autonomic compromise on their left side. It has been also found that the gastric emptying is faster in the RLDP compared to LLDP, requires the stomach to pump its contents against gravity .…”

“…Moreover, the LLDSP is associated with increased sympathetic nervous activity compared to RLDSP . Some reports have suggested that the RSSP preference by HF patients may be a self‐protecting mechanism to augment cardiac output and to attenuate the imbalance of cardiac autonomic nervous activity . It has been shown that the LLDP increases left atrial diameter, facilitates the venous return, and decreases mean systemic arterial pressure .…”

“…This trepopnea improves when turning over to the RLDSP . There have been suggested mechanisms to explain this preference including the enlarged heart beating against the left chest wall, increased ventricular preload, elevation of the pulmonary capillary and venous pressures, and increased cardiac sympathetic nervous activity in LLDSP, however, the underlying mechanisms remain unclear.…”

“…In particular, E and E/A appear to reflect left ventricular preload and diastolic function, respectively (Stoddard et al 1989). Considering that a decrease in preload in the left ventricle has been observed in the right recumbent position in patients with congestive heart failure (Berensztein et al 1996) and could be related to changes in the ANS activity with body positioning, it was considered to be important to assess the left ventricular preload and diastolic function in the supine, left recumbent and right recumbent positions in this echographic study.…”

Some studies have reported that recumbent position may have advantages in patients with heart disease and in pregnancy. However, it remains controversial whether recumbent position affects autonomic nervous system activity and hemodynamics in healthy adults. The aim of this study was to evaluate alterations in heart rate variability (HRV) and hemodynamics in the supine, left recumbent and right recumbent positions in healthy young adults. A total of 80 participants aged 22.8 ± 3.1 years were enrolled in this observational study. Fifty-eight volunteers (29 men and 29 women) maintained the supine position followed by the left and right recumbent positions, while electrocardiographic data were recorded for spectral analysis of HRV to assess cardiac vagal nerve and sympathetic nerve activities. The heart rate (HR) was significantly lower in the left recumbent position than in the other positions. There were no statistically significant differences in HRV among the three positions. Considering the possibility that the echographic procedure affects autonomic nervous system (ANS) activity, the other 22 participants (11 men and 11 women) underwent an echographic evaluation of hemodynamics in the heart and inferior vena cava (IVC) across the three positions. Although a low HR was also observed, there were no statistically significant differences in the IVC or the heart blood volume between the supine and the left recumbent positions. A postural change to the left recumbent position does not affect the cardiac blood circulation or ANS activity, though it does decrease HR in healthy young adults. This finding indicates that the lower HR in the left recumbent position is not attributable to the ANS activity.

Die linksventrikuläre Vorlast nimmt in Linksseitenlage zu und in Rechtsseitenlage ab [2]. Aus diesen Gründen liegen Patienten mit eingeschränkter linksventrikulärer Funktion bevorzugt in Rechtsseitenlage.…”

Most patients with chronic heart failure feel uncomfortable in left lateral decubitus position (LLD). They suffer from trepopnea. In LLD position cardiac sympathetic activity and preload are increased. Cardiac output is decrased. The right lateral decubitus position (RLD) can help to avoid discomfort in heart failure. RLD position may be a self-protective strategy of patients with heart failure to gain preferable hemodynamic parameters.
