Causes for Sinus Bradycardia
Training
Beta blocker
Decreased SA node automaticity Vagal response (suctioning, ICH)
Causes for Sinus Dysrhythmia
Infection
Digitoxin toxicity
Fever
Rx underlying cause
What can wandering atria pacemaker progress into?
A Fib
Atrial arrhythmia are aka
Premature atrial complex PAC
PT implications PAC
Emotional distress Caffeine Nicotine Alcohol MI
What can PAC progress into
A fib
Causes for a flutter
Beta blockers
Cardio-version
converting tachycardia or atrial arrhythmia to normal with surgery or drugs
PT implications A flutter
Mitral valve disease CAD MI Stress Hypoxemia Pericarditis
Cases a Fib
Age CHF, MI Digitoxin toxicity Drug use Stress

Main cause of stroke
Irregular pulse
Causes A fib
