Figure 4 Hemodynamic values after resuscitation. Mean arterial pressure (MAP) (Panel A), peak left ventricular pressure (PLVP) (Panel B), left ventricular dP/dt (Panel C) and thermodilution cardiac output (CO) (Panel D) during the 60 min postresuscitation observation period are depicted. Significant differences were not observed between defibrillation waveforms (monophasic n = 18 animals; biphasic n = 20 animals).
