A study on heart rate variability of patients with different coronary artery disease[J]. Journal of Chongqing Medical University, 2007,(5):513-514. DOI: 10.13406/j.cnki.cyxb.2007.05.014.
Objective:To investigate heart rate variability(HRV)of patients with different coronary artery disease.Methods:HRV was evaluated by using 24-hour Holter monitoring in 26 patients with stenosis of LAD
22 patients with stenosis of LCX and 28 patients with stenosis of RCA
and compared with age-matched normal controls.Results:HRV time and frequency domain index were lower among all patients with coronary disease than normal controls.As compared with different coronary artery dis- ease
HRV index was lower among patients with stenosis of LAD than patients with stenosis of LCX and stenosis of RCA. Conclusions:Our results suggest that HRV is decreased in patients with coronary artery disease.And HRV is significantly de- creased in patients with stenosis of LAD.
