ABSTRACT
<p><b>AIM</b>To establish a novel arrhythmia model in rats.</p><p><b>METHODS</b>Coronary artery occlusion was produced in hyperlipidemic rats after the animals were fed a high fat and cholesterol chow for 15 days. The incidence, duration and score of arrhythmias were determined 1 hour after coronary occlusion.</p><p><b>RESULTS</b>The incidence, duration and score of arrhythmia induced by coronary artery occlusion increased significantly in hyperlipidemic rats compared with those in normal rats (P < 0.05). In normal rats, pretreatment with amiodarone 60 mg x kg(-1) or verapamil 25 mg x kg(-1) 3 days before coronary artery occlusion did not influence the incidence, duration and score of arrhythmia (P > 0.05). In hyperlipidemic rats, amiodarone 60 mg x kg(-1) decreased the incidence, duration and score of arrhythmia (P < 0.05), but not verapamil 25 mg x kg(-1) (P > 0.05).</p><p><b>CONCLUSION</b>The novel arrhythmia model induced by coronary artery occlusion in hyperlipidemic rats is reliable and similar to the pathophysiological state in human being.</p>
