Electrocardiographic data collected in week 12 of the 12-week study period from telemetric monitored control and Hcy-treated animals

Parameter	Control (n=5)	Hcy-treated (n=6)	P
Heart rate (beats per minute)	511 ± 46	548 ± 62	>0.05
RR (ms)	106.5 ± 3.6	103.6 ± 3.3	>0.05
PR (ms)	33.8 ± 0.7	37.6 ± 1.3	<0.05
QRS (ms)	17.7 ± 0.8	23.9 ± 1.3	<0.05
QTc (ms)	37.0 ± 0.8	49.5 ± 1.8	<0.01

Heart rate presented in as mean ± SD. RR, R-to-R interval (ms); PR, P-to-R measurements reflecting atrial depolarization (ms); QRS complex, reflecting atrial repolarization and ventricular depolarization (ms); QTc, corrected QT time, reflecting ventricular depolarization and repolarization (RR, PR, QRS and QTc data presented as mean ± SE).
