Cardiac conduction and rhythm disorders

cardiac dysrhythmias

abnormal electrical conduction or automaticity

vary in severity

can be atrial or ventricular

cardiac dysrhythmias causes

acid-base imbalance

hypoxia

drugs

electrolyte imbalance

stress

MI

caffeine

nicotine

congenital disorders

meds

Cardiac dysrhythmias dx

EKG

lab tests

stress test

electrophysiology

Atrial flutter

Very regular rhythm

atria beat rapidly

atrial fibrillation

extremely chaotic and irregular

predisposes pt to clot formation

heart blocks

abnormalities of impulse conduction

occurs when conduction between atria and vetricles is interrupted
