2.6 Premature Contraction Detection (PC)
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
the regular rhythm, they may come in early or cause a significant pause regarding your perceivable
pulse. This is called palpitations, 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 profile 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
contractions (
PC
). 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 physician, if either the
PC
icon occurs
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.
2.7 Tachycardia Detection (TACH)
A fast heart rate of higher than 100 beats per minute (bpm) in adults. Unless being caused by
physical or mental stress, a tachycardia may be an indicator for both cardiac (e.g. Coronary heart
disease, valvular disorder), or extra-cardiac disorders (e.g. hyperthyroidism, fever, hypoxemia),
as well as medication and stimulant substance side effects (e.g. caffeine). The unit is able to
detect Tachycardia (TACH). The
ARR
and
TACH
icons are displayed right after the measurement if
tachycardia has been detected.
NOTE:
It is strongly recommended, that you consult your physician, if either the
TACH
icon occurs
several times, or, if your
TACH
is known to your doctor, but the incidence of
TACH
readings changes
over time. Your doctor will then be able to provide all required medical test and possible therapeutic
procedures.
2.8 Bradycardia Detection (BRAD)
A slow heart rate of less than 55 beats per minute (bpm) in adults. Unless not genetically
determined or subsequent to a high cardiac endurance training adaptation, bradycardia may be
related to multitude of cardiac disorders (e.g. valvular heart disease, heart failure) or extracardiac
disorders (e.g. hypothyroidism, electrolyte imbalance) or medications (e.g. beta-receptor blocker).
This unit is able to detect Bradycardia (BRAD). The
ARR
and
BRAD
icons are displayed right after
the measurement if bradycardia was detected.
