Effects of Dantrolene on Arrhythmogenicity in Isolated Regional Ischemia-Reperfusion Rabbit Hearts with or without Pacing-Induced Heart Failure

Figure 4

Effects of dantrolene on Cai decay. (a) and (b) representative examples of the distribution of Ca2+ decay time in the non-IR and IR zones at baseline and during dantrolene infusion in the HF and non-HF groups, respectively. Dantrolene had no significant effects on Cai delay in either group. The number on each subpanel is the value (ms). The right subpanel illustrates the mapping field, and (A) to (H) indicate sites where the Cai decay time was measured. LAA: left atrial appendage; IVS: interventricular sulcus.
