ECG results in 3–4 month old WT and Fabry KO mice.

<p>Surface ECGs were obtained in lightly anesthesized mice. Data represent the means ± SE. Statistical significance was determined by pair-wise comparisons with a Tuckey-Kramer test, or χ² analysis.</p><p>WT, wild-type; KO, knockout; SDNN, standard deviation of normal RR intervals; APC, %of animals with atrial premature contractions during 10 min recording.</p>*<p>P<0.05,</p>**<p>P<0.05 by for χ² analysis.
