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.

A method for simultaneously measuring blood pressure and detecting pulse arrhythmia, said method comprising steps of
- detecting 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.
