Figure 6: Effects of age and frailty on atrial conduction velocity in paced atrial preparations.
From: Atrial structure, function and arrhythmogenesis in aged and frail mice
(A) Representative activation maps in atrial preparations from a young mouse and an aged mouse paced at a fixed cycle length of 125 ms. (B and C) Summary of the effects of age on right atrial (B) and left atrial (C) conduction velocity. Data analyzed using Student’s t-test; n = 10 young and 40 aged mice. (D and E), linear regression analysis of right atrial (D) and left atrial (E) conduction velocity as a function of FI score; n = 50 mice.
