Figure 4. Close linkage between the occurrence of reentry and APD alternans in fibrotic in vitro NRVM cultures.

Figure 4

(a) Probability of successful stable reentry induction in cultures showing APD alternans or no APD alternans. (b) Probability of occurrence of APD alternans during high-frequency pacing in cultures showing stable reentry or no reentry induction. (c) Relationship between the number of APIs and arrhythmia complexity (i.e., the number of PSs).
