1. INTRODUCTION Peripheral arterial disease is a chronic disorder which affects blood flow to lower limbs. Intermittent claudication decreases blood flow to lower limbs. Heart Rate Variability is a non-invasive tool for determining cardiovascular function.
THE AIM: to investigate whether HRV could be a marker of the state of the disease in intermittent claudication.

4. DISCUSSION AND CONCLUSION RMSSD and SampEn parameters of HRV are not a valid method for researching the state of the disease in intermittent claudication. The sensibility of these methods is not enough accurate for detecting differences between controls and claudicants. Despite HRV is recommended for screening cardiovascular diseases, this study concludes that it does not provide useful information in intermittent claudication in terms of rMSSD and SampEn.
