Heart rate analyzer

摘要

A heart rate analyzer responsive to the R wave of successive ECG complexes of a patient. The intervals between successive ECG complexes are continuously counted and summed for a first number of successive complexes. First electrical representations of the average values of the intervals are generated over the first number of complexes, the number being no greater than two. The second average of the same intervals is generated for a second number of successive numbers of complexes greater than the first and electrical representations thereof are produced. These electrical representations are trapped and at least a maximum value of the first representation and a minimum value of the second representation are held. These maximum and minimum values are then converted to corresponding minimum and maximum heart rates respectively. Lastly each R wave signal generated over a predetermined period of time is counted thereby providing an indication of the average heart rate.
