Phases of the Cardiac Cycle
Conducting System
Anatomy of the Heart
Heart Blood Supply
100
depicts atrial depolarization
What is the P wave
100
follows atrial systole
What is atrial dystole
100
also referred to the pacemaker
What is the sinoatrial node
100
what are the 4 chambers of the heart
What is right atrium and ventricle; left atrium and ventricle
100
supplies blood to the right atrium, both ventricles, portions of the conducting system if the heart
What is right coronary artery
200
abnormal patterns of electrical activity on the heart
What is cardiac arrhythmicas
200
amount of blood remaining in the ventricles when the semilunar valves close
What is end-systolic volume (ESV)
200
distributed through the heart and their activity is recorded by and EKG
What is electrical impulses
200
the right atrium receives blood from the systemic circuit through
What is the superior and inferior vena cava
200
the vein that drains blood from the region supplied by the AV(atrioventriclar) artery
What is great cardiac vein
300
the time between waves
What is segments and intervals
300
ventricular contraction pushes AV valves closed but doesn't open semilunar valves
What is ventricular systolic phase one
300
assumes command of the SA node or internodal pathways are damaged
What is the atrioventricular node (AV node)
300
fibrous cords that stabilizes the position of the AV valves in the heart, preventing back flow during ventricular systole
What is chordae tendineae
300
disease that has areas of partial or complete blockage of coronary circulation
What is coronary artery disease
400
indicates abnormalities in the electrical activity in the heart
What is QRS complex
400
atrial contraction forces a small amount of additional blood into relaxed ventricles
What is the start of atrial systole
400
radiate from apex towards base of heart and conducts action potentials very rapidly
What is perkinje fibers
400
what prevents the AV valves from swinging into the atria
What is papillary muscles
400
interconnections between arteries
What is arterial anastomoses
500
indicates the time required for the ventricles to undergo a single cycle of depolarization and repolarization
What is the Q-T interval
500
all chambers are relaxed and ventricles fill passively
What is ventricular diastole (late phase)
500
sits within the floor of the right atrium near the opening of the coronary sinus
What is atrioventricular node (AV node)
500
radiate from apex towards base of heart and conducts action potentials very rapidly
What is cardiac skeleton (fibrous skeleton)
500
artery that swings around the pulmonary trunk and runs along the surface within the anterior interventricular sulcus
What is anterior interventricular artery
