Which represents time for the passage of the electrical impulse through the atrium, causing atrial depolarization. Which represents time for depolarization of both ventricles.
Which represents time for ventricular repolarization.
Which represents the time taken for the entire electrical depolarization and repolarization of the ventricles.
["QRS complex", "T wave", "P wave" , "P-R interval", "QRS interval", "ST segment", "QT interval"
In atrial fibrillation, the atria do not contract correctly, and not all blood exits this
chamber. The blood pools in the atria, and this can promote blood clot formation. If a
blood clot forms in the left atrium, it can get pumped from the left ventricle, get
caught in a capillary bed and cause a(n):
pulmonary embolus
2) inferior vena cava filter
3) deep vein thrombosis
4) cerebral vascular accident (CVA)

- Roberto is a 78-year-old male who has recently been diagnosed with Class III Congestive Heart Failure (CHF). His physician told him that his left ventricle has become stiff and cannot relax. Although there is no current treatment that can “fix” Roberto’s condition, he is prescribed two medications: an ACE inhibitor and beta blockers. There are multiple types of CHF. Which of these types does Roberto have? Systolic heart failure Diastolic heart failure Right-sided heart failure None of these choices is correct.arrow_forwardThe right and left atria of the heart look alike and perform similar functional demands. The right and left ventricle are very different, structurally and functionally. Why are the atria similarities and the difference in the ventricles significant in the role they play in the functional activity of the heart? How would these differences be manifested on an EKG, with details given to the P wave and QRS complex?arrow_forwardIn a patient with a ventricular septal defect, blood is ejected from the left ventricle into the right ventricle during isovolumic contraction phase of the cardiac cycle. Which pressure volume loop from the left ventricle is most likely from a patient with a ventricular septal defect? The dashed line is a normal loop for reference in all figures.

- Classify the three congenital heart defects—ventricular septal defect, coarctation of the aorta, and tetralogy of Fallot (Figure 19.18)— according to whether they produce (1) mixing of oxygenated and unoxygenated blood, (2) increased workload for the ventricles, or (3) both of these problems.arrow_forwardTia developed Rheumatic heart disease when she was 19 years old that caused stenosis of her mitral valve. Long-standing mitral stenosis led to left atrial enlargement. She is 29 now and her cardiologist, Dr. Irma Wu, advised her replacement of the mitral valve. According to her doctor, after the valve replacement, she would require life-long blood thinners. Using your knowledge of physiology, explain how can clot formation be prevented prophylactically?

- Read the following statements: Statement A: Ventricular diastole leads to reduction in ventricular pressure that causes closure of semilunar valves and preventing the backflow of blood into ventricles. Statement B: Ventricular systole increases the ventricular pressure causing the closure of bicuspid and tricuspid valves due to attempted backflow of blood into the atria. Choose the correct option. Only A is correct Only B is correct Both A and B are incorrect Both A and B are correctarrow_forwardAs a result of ventricular depolarization (T wave), calcium ions are returned to the sarcoplasmic reticulum and ventricular muscles relax. As the myocardium relaxes, the semilunar valves close. At this time which of the following is true? Group of answer choices (A) ventricular pressure > aortic pressure > atrial pressure (B) atrial pressure > ventricular pressure > aortic pressure (C) aortic pressure > ventricular pressure > atrial pressure (D) aortic pressure > atrial pressure > ventricular pressurearrow_forwardRegarding the cardiac cycle at resting HR, when in the cycle does ventricular filling occur?
