Q

conduction starts in SA
follows path through atria
hits AV junction (AV NODE)
follows path through bundle branches
and through ventricles

Q

ectopic beat originate in ventricle
(delay or miss contraction)
(side effect to caffeine/ nicotine)
ok to exercise w no side effects

if it’s increases- sign of MI

Q

lack of oxygen to myocardium
muscle damage is irreversible
(take aspirin/ nitroglycerin)

(low level but no aerobic)

14
Q

avoid HR greater than 15, can exercise
“irregularly irregular”
take 1 min for HR
1/3 cardiac arrhythmia
1/5 every stroke

*clots in atria, take blood thinners
risk MI PE & stroke
