Abstract :
This paper comprises the analysis of rats electrocardiogram (EKG) recorded within a toxicology study. Acquired signals are processed to assess changes in heart response to air pollution in Mexico City, by means of Heart Rate Variability (HRV) using the SDNN index. EKG records were acquired along 8 days from 12 rats, divided into control group, supplied with filtered air (FA), and exposed group, who was provided a concentration of fine particles (FP) in the polluted air of Mexico City. After 8 recordings, FP group showed a significant decrease (p=0.028) in SDNN index values, while FA group showed no significant change (p=0.752) in SDNN index values.
