• Resumen

  • A widely used animal model in foetal and neonatal studies is the avian embryo. Some of their embryonic variables can be currently monitored, including the heart rate, which is a natural indicator of cardiac functioning and general development. Different non-invasive acquisition systems to detect the heart rate have been designed, most of them based on ballistocardiography. This method is founded on the fact that the motions generated by the cardiovascular system induce some micro-vibrations in the eggshell that can be recorded by external sensors. The main objective of this study is to present an innovative acquisition system to measure the heart rate of chicken embryos noninvasively. The methodology is based on the detection of ballistocardiographic signals employing a digital accelerometer. The wavelet transform is used to process the obtained ballistocardiogram. With the described tools, it was possible to detect cardiac and non-cardiac embryonic signals. The heart rate was successfully measured from the ballistocardiogram, and the results agreed with the ones found in the literature.
