Figure 1. Flow chart of ventricular pressure clamping.

Figure 1

The pressure clamp was controlled by analog voltages from the interface generated in response to pre-edited stimulus protocols. The double ended arrow denotes the pressure transfer with a connecting tube. The left ventricular pressure (LVP), epicardial electrocardiogram (ECG) and left ventricular monophasic action potential (LVMAP) were recorded synchronously.
