Improved ambulatory blood pressure and heart rate monitoring and recording apparatus and method are described. The apparatus uses an auscultatory transducer connected to a microprocessor-based circuit for sensing, validating and recording systolic and diastolic pressure in the cuff-surrounded limb of the patient, and for measuring heart rate. The improved method calculates, and records in the same blood pressure and heart rate data record, an alphanumeric figure of merit, or alternatively a numeric quality index, based upon Korotkoff sound frequency and amplitude criteria. In another improved method, the maximum pressure to which the cuff is pressurized for each measurement is made to track the individual patient\s systolic blood pressure to ensure reliable blood pressure readings without unneccessary constriction of the patient\s limb.

Ambulatory patient blood pressure monitoring and recording apparatus comprising: means for monitoring and recording a patient\s blood pressure over a given interval of time; means operatively connected with said monitoring-recording means for qualitatively characterizing such recorded blood pressure

Ambulatory patient blood pressure monitoring and recording apparatus comprising: means for monitoring and recording a patient\s blood pressure over a given interval of time; means operatively connected with said monitoring-recording means for qualitatively characterizing such recorded blood pressure, said characterizing means including means for evaluating such blood pressure based upon predetermined criteria including the number of Korotkoff sounds detected over said given interval of time to produce quality indicia regarding the merit of such recorded blood pressure, said characterizing means further including means for encoding such quality indicia to produce symbolic data interpretable as being representative of such quality indicia.
