normal sinus rhythm




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
– SA node doesn’t fire
– notice absence of P-wave for a complete cycle (a missed cycle)
length of pause ≠ multiple of normal rate (block)
