Heart Vocab Notes Flashcards
Artificial pacemaker
battery-powered device that prevents the heart from beating too slowly
Atrial fibrillation
Type of arrhythmia/abnormal heart beat
Autonomic nervous system
responsible for controlling the bodily functions like breathing
AV node
The electrical relay station between the upper+lower chamber of the heart
Bradycardia
Slow heart rate
Bundle branches
Part of the electrical system of the heart rate
Bundle of His
Elongated segment connecting the AV node left + right bundle branches of the septal branch
Ectopic focus
Area that begins to release electrical stimuli outside the normal different heart conditions
Electrocardiogram
records the electrical signal from the heart to check for different hear conditions
Normal sinus rhythm
Rhythm that orginates from sinus nude + describes the characteristics rhythm of the healthy human heart
Purkinje fibers
Any of the specialized cardiac muscle fibers forming a network in the ventricular walls that conduct electric impulses for the contractions of the ventricles
Sinoatrial nude
Generates on electrical signals that causes the upper heart + chambers(atrial) to contract
Tachycardia
Heart rate over 100 beats a minute
Ventricular fibrillation
irregular heart rhythm(arrhythmia) where the lower heart chambers controut in a very rapid + uncoordinated manner
