Mean left atrial pressure (MLAP), mean arterial blood pressure (MABP), heart rate (HR) and the peak intra-tracheal pressure (PITP) values when investigating the effect of acutely elevating the left atrial pressure (LAP) above 25 mmHg on the activity of rapidly adapting receptors in rabbits with chronic pulmonary venous congestion

	Initial control period	LAP +25 mmHg	Final control period
MLAP (mmHg)	5.2 ± 0.4	28.1 ± 1.2†	6.8 ± 1.2
MABP (mmHg)	58.0 ± 4.5	21.0 ± 4.3†	57.2 ± 8.2
HR (beats min−1)	211.0 ± 9.9	152.3 ± 18‡	200.6 ± 16.4
PITP (mmHg)	4.1 ± 0.1	5.1 ± 0.1†	4.2 ± 0.2

^†Significantly different from initial control and final control periods (P < 0.01, t test).

^‡Significantly different from the initial control period (P < 0.05, t test).
