start with minimal activity and work up as the are able to tolerate without symptoms of uncontrolled a fib
what is the main measure of CO that we use as PTs?
BP
if HR is high and BP is stable, is CO able to keep up with increased HR?
yes
if HR is high and BP is decreased, is CO able to keep up with increased HR?
no
what is the HR of rapid ventricular response (RVR)?

what is premature atrial contraction (PAC)?
ectopic atrial foci outside of the SA node causing early atrial defibrillation
what would PAC look like on EKG?
early p wave appears different to other p waves and may be hidden in the t wave
