An automated method and improved device provide a measurement of blood flow through the heart by the detection and analysis of radioactivity emitted by a radioactive tracer introduced into a patient's bloodstream. Real time, cardiac cycle by cardiac cycle information is processed and displayed to provide diagnostically useful information on an essentially ongoing basis as the patient is being tested.

Method and apparatus for characterizing blood flow through the heart

A method and improved apparatus for locating data of interest on a cathode ray tube display in a system for characterizing blood flow through the heart is disclosed. Apparatus comprising an adjustable cursor control circuit is utilized to generate a plurality of stable horizontal or vertical cursor lines on the cathode ray tube display thereby enhancing the user's ability to locate data of interest.

Method and apparatus for locating data characterizing blood flow through

A method and improved apparatus for automatically locating the QRS portion of an electrocardiographic signal and for generating a corresponding synchronization pulse is disclosed. Properties associated with the QRS portion of an electrocardiographic signal are utilized in the implementation of an adaptive peak detector capable of accurately operating with electrocardiographic signals varying in amplitude or polarity. The adaptive peak detector is also capable of discriminating against signal components lying outside certain predetermined limits.
