Figure 1. Quantifying basic electrophysiology parameters via optical mapping in isolated hearts.

Figure 1

Comparison of APD70 (left panels) and conduction velocity (CV) (right panels), at BCL=250 ms, in control versus diabetic hearts in (A.) normal [K+]o levels (4mM), (B.) low [K+]o levels (2mM), hypokalemia, and (C.) high [K+]o levels (12mM), hyperkalemia.
