mia Respiratory - Circulatory interaction
Rate INCREASES with INSPIRATION (IN=IN)
3. Sinus Bradycar- <60
dia normal sinus rhythm

dia normal sinus rhythm
5. Premature Atri- Heart Rate: Depends on underlying rhythm
al Contraction Regularity: Interrupts the regularity of underlying rhythm
(PAC) P-Wave: can be flattened, notched, or unusual. May be
hidden within the T wave
PRI: measures between .12-.20 seconds and can be pro-
