Extra abnormal heartbeats generated in irregular excitation sites
of your heart, either in the atria (PAC), the ventricle (PVC) or the
cardiac conduction nodes (PNC). These extra beats may disrupt
your regular rhythm, they may come in early or cause a signifi-
cant pauses regarding your perceivable pulse. This is called pal-
pitations, which can be felt in your chest. They may occur as
isolated, single events, as a series of irregular pulses or can be
distributed all over your pulse beats. If they are not related to
mental stress, or acute demanding physical load, they may be a
marker for a multitude of cardiac disorders.
Some of these disorders go along with an elevated risk pro-
file for ischemic events, either in the heart (e,g, coronary heart
disease) or outside the heart, e.g. an elevated risk for a stroke.
Some PCs may indicate on valvular or myocardial disorders and
become very important if a myocarditis (infection of the heart
muscle) is suspected. This unit is able to detect premature con-
tractions (
). The ARR and PC icons are displayed right after
the measurement if premature contractions have been detected.
Note: It is strongly recommended, that you consult your phy-
sician, if either the PC icon occurs newly for several times, or,
if your PC is known to your doctor, but the incidence of PC
readings changes over time. your doctor will then be able to
provide all required medical test and possible therapeutic
procedures.
Note: The presence of a cardiac pacemaker may impair the
AFib detection by PARR.
