The most chronologically close to nowadays doctor of Middle Ages who compiled detailed doctrine of pulse was the greatest physician of Arabian world Abu Ali Ibn-Sina (Avicenna) who had lived in 980–1037. The authors studied the doctrine of pulse and diagnosis of diseases using the characteristics of Avicenna’s description in the context of XXI century cardiology and evidence of hypothesis about the importance of ancient physicians’ pulse doctrine for their contemporary colleagues. As the source (reference material) and methodological approach for the study was selected analysis of the main lifework of the greatest physician of Middle Ages Avicenna (980–1037) “The Canon of medicine” and two contemporary clinical guidelines on internal diseases propedeutics, historical medical analysis and comparison of Avicenna’s doctrine of pulse with statements outlined in the guidelines of the turn of the XXI century. It was established that in Middle Ages to diagnose pulse state associated with some or other diseases there were used far more sophisticated techniques than nowadays. For example physicians then could study every tact separately describing four-tact pulse wave. The analysis shows that the main statements of Avicenna pulse doctrine are extant. Similarity and differences in comprehension of some or other pulse types and their reasons were revealed. At the same time some concepts were gone and others were far more sophisticated than contemporary conceptions which could be assignable to pulse diagnosis in old time. In the frame of the studies carried out there was concluded that artistic legacy of the genius physician of the past did not lose its relevance up to now and should be considered when studying contemporary types and reasons of rhythm disturbances and heart conductivity.
