Method and a device for non-invasive measurement of the blood pressure and for detection of arrhythmia
First Claim
1. A method for simultaneously measuring blood pressure and detecting pulse arrhythmia, said method comprising steps ofdetecting a plurality of consecutive blood pressure pulses in an artery with an oscillometric blood pressure monitor, measuring values of pulse time differences between said plurality of detected consecutive pulses, storing said values in a storage unit, calculating the distribution of said pulse time differences, comparing said distribution of the pulse time differences with a predetermined reference acceptable pulse time difference distribution, and generating a warning signal if the reference acceptable pulse time difference distribution differs substantially from the calculated distribution.

Abstract
In a device or in a method for oscillometric measurement of the blood pressure, the pulse time differences are determined associated with the measurement of the blood pressure. Subsequent pulse time differences are stored in a storing unit (15). A distribution of pulse time differences is calculated in a calculating unit (16) and compared in a comparing unit (17) with predetermined reference values. If the distribution or the values of pulse time differences exceed a predetermined amount, an indication means (19) is activated which indicates existence of arrhythmic activities.
