What is a PREMATURE COMPLEX?

Occurs when a cell other than the SA NODE becomes irritable and fires off an impulse.

**Because of automaticity, these cells can depolarize by themselves

DECREASED VENTRICULAR FILLING = DECREASED CARDIAC OUTPUT

62

Complications of A-Fib (2)

1) Blood pooling in atria can lead to thrombus / clot formation increasing risk of stroke , MI, PE

2) If HR is too rapid and irregular, ventricular filling time is decreased so cardiac output decreases

Clinical Symptoms of Dysrhythmias / poor perfusion

"WASP HAD CPU"

W-eakness
A-ngina
S-OB
P-ale skin

H-ypotension
A-nxiety
D-izziness

C-onfusion
U-rine is decreased
P-alpitations

AV BLOCKS

Where are the electrical impulses delayed?
Does the SA NODE function normally?

*Electrical impulses are delayed or blocked in the AV NODE or INTRAVENTRICULAR conduction system

*Yes, the SA NODE functions normally
