The term 'stenosis' in cardiovascular medicine refers to:
Answer: Narrowing or constriction of a vessel or valve opening
Stenosis describes an abnormal narrowing of a blood vessel or heart valve opening that restricts flow.
Which layer of the heart wall contains the cardiac muscle cells responsible for contraction?
Answer: Myocardium
The myocardium is the middle muscular layer of the heart wall composed of cardiac muscle cells (cardiomyocytes).
The term 'bradycardia' is defined as a heart rate:
Answer: Less than 60 beats per minute
Bradycardia is defined as a resting heart rate below 60 beats per minute.
The right coronary artery (RCA) most commonly supplies which structure?
Answer: Sinoatrial node and right ventricle
The RCA typically supplies the sinoatrial node, right ventricle, and inferior wall of the left ventricle.
What does the term 'ejection fraction' (EF) measure?
Answer: Percentage of blood ejected from the ventricle with each beat
Ejection fraction is the percentage of end-diastolic volume pumped out of the ventricle per heartbeat.
The anatomical term 'interventricular septum' refers to:
Answer: The muscular wall dividing the left and right ventricles
The interventricular septum is the muscular and membranous partition separating the two ventricular chambers.
Which term describes the period during which the ventricles are filling with blood?
Answer: Diastole
Diastole is the phase of the cardiac cycle when the ventricular muscle relaxes and chambers fill with blood.
