, One of the most useful and
commonly used diagnostic tools is
electrocardiography (EKG) which
measures the heart's electrical
activity as waveforms. An EKG uses
electrodes attached to the skin to
detect electric current moving
through the heart. These signals are
EKG transmitted to produce a record of
interpretation cardiac activity. Arrhythmia or
dysrhythmia are disturbances in the
normal cardiac rhythm of the heart
which occurs as a result of
alterations within the conduction of
electrical impulses. These impulses
stimulate and coordinate atrial and
ventricular myocardial contractions
that provide cardiac output.
, Sinus tachycardia is a heart rate
greater than 100 beats per minute
that originated from the sinus node.
Rate: 100 to 180 beats per minute
P Waves precede each QRS
complex
PR interval is normal
QRS complex is normal
Conduction is normal
Sinus Rhythm is regular
Tachycardia Causes of sinus tachycardia may
include exercise, anxiety, fever,
drugs, anemia, heart failure,
hypovolemia and shock. Sinus
tachycardia is often asymptomatic.
Management however is directed at
the treatment of the primary cause.
Carotid sinus pressure (carotid
massage) or a beta blocker may be
used to reduce heart rate.
