Dysrhythmias (Including EKG Strips)
questions with complete verified
solutions
Normal Sinus Rhythm - answer Refers to a rhythm that originates in the
SA node @ a rate of 60-100 BPM and follows normal conduction pattern of
the cardiac cycle.
Sinus Bradycardia - answer The conduction pathway is the same as that in
sinus rhythm but the SA node fires @ a rate of less than 60 BPM. May be
normal in athletes.
Symptomatic Sinus Bradycadia S/S - answer Pale, cool skin, hypotension,
weakness, angina, dizziness or syncope, confusion or disorientation, and
shortness of breath.
Symptomatic Sinus Bradycardia Tx - answer Admin of atropine, or
pacemaker therapy. If due to drugs; must be held, discontinued, or
dosages reduced.
Sinus Tachycardia - answer The conduction pathway is the same as that in
sinus rhythm. The discharge rate from the sinus node increases because
of vagal inhibition or sympathetic stimulation. the sinus rate is 101-200
BPM.
Sinus Tachycardia S/S - answer Dizziness, dyspnea, and hypotension due
to decreased CO. Increased O2 consumption due to increased HR. Angina
or an increase in infarction size may accompany this disorder in pts with
CAD or AMI
Sinus Tachycardia Tx - answer The underlying cause determines
treatment, eg.) pain management if d/t pain. In stable pts vagal
manuevers can be attempted. Beta-adrenergic blockers
