Relias Assessments Assistance Material DYSRHYTHMIAS
WITH QUESTIONS AND 100% SURE ANSWERS
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 transmitted to produce a record of cardiac activity. Arrhythmia or
EKG interpretation
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
Sinus Tachycardia
Conduction is normal
Rhythm is regular
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.

Sinus bradycardia is a heart rate less than 60 beats per minute and originates from the
sinus node (as the term "sinus" refers to sinoatrial node). It has the following
characteristics
Rate is less than 60 beats per minute
P Waves precede each QRS complex
PR interval is normal
QRS complex is normal
Sinus Bradycardia
Conduction is normal
Rhythm is regular
Causes may include drugs, vagal stimulation, hypoendocrine states, hypothermia, or
sinus node involvement in MI. This arrhythmia may be normal in athletes as they have
quality stroke volume. It is often asymptomatic but manifestations may include:
syncope, fatigue, dizziness. Management includes treating the underlying cause and
administering anticholinergic drugs like atropine sulfate as prescribed.
