Key result
The right lateral decubitus position led to the highest vagal modulation and lowest sympathetic modulation compared to supine and left lateral decubitus positions in patients with Q wave myocardial infarction.
Why the study?
Does the right lateral decubitus position improve vagal modulation compared to the supine position in patients with acute myocardial infarction?
Observational (n=121)
No
Does the right lateral decubitus position improve vagal modulation compared to the supine position in patients with acute myocardial infarction?
The right lateral decubitus position acts as an effective vagal enhancer and sympathetic suppressor in patients with Q wave myocardial infarction, offering a simple non-pharmacological method to modulate autonomic tone.
May support right lateral positioning for autonomic modulation in Q-wave MI; hypothesis-generating, needs prospective confirmation.

Kuo et al. (2000) conducted an observational in Acute myocardial infarction (n=121). Right lateral decubitus position vs. Supine and left lateral decubitus positions was evaluated on Spectral indices of autonomic modulation of the heart (vagal and sympathetic modulation). The right lateral decubitus position led to the highest vagal modulation and lowest sympathetic modulation compared to supine and left lateral decubitus positions in patients with Q wave myocardial infarction.
