Abstract
Heart monitoring and storing apparatus is disclosed for evaluating heart activity signals to determine if valid, for identifying a characteristic of the valid heart activity signal, and for storing the signal into a corresponding location of a memory depending upon the characteristic of the heart activity signal. Such apparatus comprises the memory including a first area and a second area, and a circuit for sampling the heart activity signals and for storing the heart signal samples into corresponding locations of such first area. There is further included an evaluation circuit for determining whether the sampled heart activity signals as stored within the first area are valid and particularly if they indicate the occurrence of a heartbeat. An addressing circuit is provided for determining the various characteristics of a valid heart signal and for selectively addressing a location within said second area to store the valid heart signal of the corresponding characteristic.
