-Medications
-inferior MI
-May feel dizzy, sob, or faint

sinus bradycardia

Supraventricular dysrhythmias

a flutter, a fib, sick cinus syndrome, pac, sinus tach, sinus brady

, -When electroventricular impulse moving through the AV node are delayed but
not blocker

first degree block

A block that has slowed conduction without missing a beat

first degree

A first degree block is characterized by a PR > ____ and asymptomatic

0.20

A heart block where the QRS is too long
-caused by heart surgery, heart disease or MI
-asymptomatic
-no treatment

bundle branch block

A heart block where the PR interval gets progressively longer until the ventricular
impulse is not conducted (QRS)
-Full beat skipped

Mobitz Type I

A drug that increases HR and is given during heart blocks to increase CO

atropine

A heart block where the AV node fails to conduct an
impulse -more Ps that QRS

-decreases HR causing lightheadedness and
dizziness -very bad because it can lead to type 3

Mobitz type 2
