Card Set Information
a stimulus that depolarize myocardial tissue
also is its property
happens every other beat
happens every third beat
recurring, regular sawtooth-shaped waves
the normal cardiac rhythm when the heart is controlled by the atrioventricular node
the ability of the cardiac muscle to depolarize in response to a stimulus
the cell returns to its resting stage
the ability of a cardiac cell to initiate an impulse
the ability of the heart muscle to move an impulse over the entire muscle mass
the ability of the heart to contract
the heart's inability to respond to a stimulus
in a phenomenon that occurs in waves, the maximal deviation of a wave from the baseline.
absence of heart muscle contraction
the priming force contributed by atrial contraction immediately before ventricular systole that acts to increase the efficiency of ventricular ejection due to acutely increased preload.
the process of restoring the heart's normal rhythm by applying a controlled electric shock to the exterior of the chest.
The ability or power to conduct or transmit heat, electricity, or sound.
a capacity for becoming short in response to suitable stimulus.
a process in which an electronic device sends an electric shock to the heart to stop an extremely rapid, irregular heartbeat, and restore the normal heart rhythm.
the process or act of neutralizing polarity as in the decrease of membrane potential.
Rapid, uncoordinated contractions of the upper or the lower chambers of the heart.
rapid vibration or pulsation
