Blood pressure measurements determined with X9 are equivalent to those obtained by
a trained observer using cu/stethoscope auscultation method, within the limits pre-
scribed by the American National Standard, Electronic or Automated Sphygmomanom-
eters. This unit is to be used by adult consumers in home, physicians’ oces, hospitals,
clinics and other medical facilities. The patient is an intended operator. Do not use this
device on infants or neonates. X9 is protected against manufacturing defects by an es-
tablished International Warranty Program. For warranty information, you can contact
the manufacturer, Rossmax International Ltd.
Attention: Consult the accompanying documents. Please read this manual care-
fully before use. For specic information on your own blood pressure, contact your
physician. Please be sure to keep this manual.
Introduction
PARR(Pulse Arrhythmia) Technology
The upper chambers of the heart (the atria) do not contract, but quiver and thus blood
is driven irregularly and with lower eciency into the ventricles. Subsequently irregular
heartbeats occurs, which mostly are associated with a fast, yet highly instable heart rate.
Pulse Arrhythmia (PARR) technology specically detects the existence of pulse arrhyth-
mia, including atrial brillation (AFib), Atrial and / or Ventricular Premature Contractions
(PC), Tachycardia (TACH), and Bradycardia (BRAD). Pulse Arrhythmia may be related to
cardiac disorders, needs medical attention and thus early diagnosis is of paramount
importance. The PARR technology detects arrhythmia during regular blood pressure
checks without any additional user skills, user interaction and measurement prolonga-
tion. Beside the blood pressure diagnosis a specic pulse arrhythmia diagnosis is pro-
vided with PARR.
Note: The PARR detection of AFib, PC, TACH and BRAD is provided with a clinically
proven high detection probability [1]. However, the sensitivity and specicity is
limited, thus most, but not all pulse arrhythmia will be detected and displayed.
In certain patients with uncommon clinical conditions the PARR technology may
not be able to detect pulse arrhythmia. This partly comes from the fact that some
arrhythmia can only be found with an ECG diagnosis, but not with a pulse diagno-
sis. Thus PARR is not meant to replace any medical ECG diagnosis by your doctor.
PARR provides an early detection of certain pulse arrhythmia, which inevitably
need to be presented to your doctor in charge.
