Premature Atrial Contraction (PAC)

Heart Rate: Depends on underlying rhythm

Regularity: Interrupts the regularity of underlying rhythm

P-Wave: can be flattened, notched, or unusual. May be hidden within the T
wave

PRI: measures between .12-.20 seconds and can be prolonged; can be
different from other complexes

QRS: <.12 seconds




Sinus Arrest/Pause
