550	287.9 ± 18.1	262.2 ± 17.8	293.5 ± 21.9	256.2 ± 22.6
500	245.2 ± 16.9	253.0 ± 15.6	255.3 ± 22.7	243.8 ± 23.3
450	206.7 ± 13.2	243.2 ± 13.7	215.6 ± 25.5	234.6 ± 25.2
400	166.6 ± 11.6	233.4 ± 12.0	180.6 ± 30.7	218.8 ± 31.1
350	127.1 ± 13.2	222.3 ± 13.1	159.3 ± 41.9	190.6 ± 40.4

Results are mean ± SD.

ARI, activation-recovery interval; DI, diastolic interval; ICMP, ischemic cardiomyopathy; SNLV, structurally normal left ventricle.
