Table 1. Changes in intraventricular pressure, mean arterial pressure, and pulse rate due to Queckenstedt's test.

Time point	IVP (mmHg)	p-value	MAP (mmHg)	p-value	PR (beats/min)	p-value
Before Q-test	3.4±2.0		88.8±12.7		348.3±69.1
During Q-test	9.9±2.2	0.008	75.3±16.7	0.008	341.2±80.5	0.515
<30sec After Q-test	3.5±1.8	0.953	87.0±13.7	0.314	337.0±76.1	0.028
>30sec After Q-test	3.5±2.3	0.594	89.0±12.0	0.953	319.3±47.2	0.173

(n = 9).

<30 sec After Q-test: less than 30 seconds after Q-test.

>30 sec After Q-test: more than 30 seconds after Q-test.

Abbreviations: IVP, intraventricular pressure; MAP, mean arterial pressure; PR, pulse rate; Q-test, Queckenstedt's test. For p-values, comparison is to the initial time point (before Q-test).
