●● electrical diastole
Answer: recovery
repolarization


●● mechanical systole
Answer: shortening
contraction
emptying


●● mechanical diastole
Answer: lengthening
relaxation
filling


●● automaticity
Answer: ability to initiate and maintain electrical rhythm

,●● excitability
Answer: ability to respond to electrical stimulus


●● conductivity
Answer: ability to transfer that electrical stimulus to the neighboring cell


●● contractility
Answer: the ability of myocardial cells to shorten and contract in
response to an electrical stimulus
force generated by the contracting myocardium under any given
condition


●● cardiac output
Answer: stroke volume X heart rate
amount of blood pumped by each ventricle in liters per minute


●● stroke volume
Answer: the amount of blood ejected with each heart beat
affects by preload, afterload, and contractility


●● preload
Answer: volume of blood in ventricles at the end of diastole
(ventricular filling)

, ●● afterload
Answer: the amount of resistance the ventricle must overcome to eject
the blood out of the heart


●● SA node
Answer: primary pacemaker of the heart
initiates electrical impulses at rate of 60-100 bpm


●● AV node
Answer: synchronizes atrial and ventricular activity
picks up slack of SA node at rate of 40-60 bpm


●● bundle of HIS
Answer: located between atria and ventricles
should be the only pathway (if not, indicates conduction issues)
next stop is R and L Bundle Branches


●● Purkinje fiber
Answer: ventricles are finally stimulated to contract
inherent rate of 30-40 bpm (if SA and AV node fail)
