CARDIAC CYCLE
This phase of the cardiac cycle occurs when the ventricles relax and fill with blood.
What is diastole?
This structure is known as the heart’s natural pacemaker.
What is the SA node?
This valve separates the right atrium from the right ventricle.
What is the tricuspid valve?
This patient position is best for assessing jugular venous distention.
What is 30–45 degrees?
This pulse is located on the top of the foot.
What is the dorsalis pedis pulse?
This heart sound is produced by closure of the mitral and tricuspid valves.
What is S1?
This structure delays the electrical impulse before ventricular contraction.
What is the AV node?
This artery carries deoxygenated blood to the lungs.
What is the pulmonary artery?
This assessment technique is performed first during a cardiovascular examination.
What is inspection?
This condition describes enlarged, twisted superficial veins.
What are varicosities (varicose veins)?
These valves open during ventricular systole to allow blood ejection.
What are the pulmonic and aortic valves?
This ECG component represents ventricular depolarization.
What is the QRS complex?
These vessels return deoxygenated blood from the body to the heart.
What are the superior and inferior vena cava?
This is the normal location of the apical impulse (PMI).
What is the 5th intercostal space at the left midclavicular line?
This term describes leg pain caused by inadequate arterial blood flow during exercise.
What is claudication?
This chamber pumps oxygenated blood to the body.
What is the left ventricle?
These fibers distribute impulses throughout the ventricles.
What are Purkinje fibers?
This side of the heart receives oxygenated blood from the lungs.
What is the left side?
This sound may indicate heart failure in adults.
What is S3?
This finding may indicate decreased peripheral perfusion when greater than 2 seconds.
What is delayed capillary refill?
This vessel carries oxygenated blood from the lungs to the heart.
What are the pulmonary veins?
This is the correct conduction pathway after the AV node.
What is Bundle of His → bundle branches → Purkinje fibers?
This valve prevents backflow from the aorta into the left ventricle.
What is the aortic valve?
This palpable vibration is caused by turbulent blood flow.
What is a thrill?
These ulcers are commonly found on the medial ankle and are associated with venous insufficiency.
What are venous ulcers?
