Figure 2. In vivo murine cardiac EP data and VT induced by programmed electrical stimulation.

Figure 2

A. The measurement of VERP and this was significantly reduced in Gαi2 (−/−) mice. B. Example of programmed electrical stimulation with one extrastimulus (S2) demonstrating VT induction. Control (TOP) shows non sustained VT induction at very short S1–S2 coupling. Gαi2 (−/−) (Bottom) mice develop sustained VT using a similar induction protocol.
