From: Haemodynamic changes during propofol induction in dogs: new findings and approach of monitoring
Values of velocity time integral*heart rate (centimetres*beats minute− 1) in dogs (n = 8) receiving a bolus of propofol at different time points. The central box represents the values from the lower to upper quartile. The middle line represents the median. Time points non-significantly different (empty circles) and significantly different (full circles) from the baseline
