abnormal murmur sound. Once the blood passes from the left to right ventricle and the semilunar valves close the final dup sound is heard (Marieb & Hoehn‚ 2015‚ 687-688). 3. The defect in Caleb’s heart allows blood to mix between the two ventricular chambers. a. Due to this defect would you expect the blood to move from left-to-right ventricle or right-to-left ventricle during systole? During systole‚ the contraction phase‚ I would expect the blood in Caleb’s heart to move from left to right

diastolic. (ventricular diastole‚ atrial systole etc.) Ventricular diastole is the period during which the ventricles are relaxing‚ while atrial diastole is the period during which the atria are relaxing. Atrial systole represents the contraction of myocardium of the left and right atria. Atrial systole occurs late in ventricular diastole. One force driving blood from the atria to the ventricles is the decrease in ventricular pressure that occurs during ventricular diastole. Ventricular systole is

NURSING: The Postoperative Phase Postoperative care of the cardiac surgery patient is challenging in that changes can occur rapidly. The preoperative condition of the patient as well as intraoperative events should be considered in postoperative care. It is essential for the nurse to anticipate the possible complications so that appropriate interventions are initiated in a timely manner in order to ensure a positive outcome for the patient. There is a flurry of activity as the patient enters

Hyperthyroidism Vs. Hypothyroidism The endocrine system is a series of glands within the body. These gland impact a lot of our body including calcium levels and what we find joy in ( the pituitary gland releases dopamine if we enjoy something). Because there are so many glands in our bodies‚ there are a lot of things that can go wrong. Two of the things that could go wrong are Hyperthyroidism (overactive Thyroid) and Hypothyroidism (underactive Thyroid). While they are both malfunctions of the Thyroid

After a full day of tests‚ Tiffany meets with Dr. Baker in his office. He explains‚ “After a careful review of all the information‚ I have discovered that Caleb has a hole in the heart muscle wall between his right and left ventricles. We call it a ventricular septal defect. That is probably why he has been so irritable and hard to feed. The hole is not very big‚ but he will still need to have surgery to repair it.” Although the thought of her tiny son having surgery is terrifying‚ Tiffany is relieved

People experience transient heart beats‚ called sinus tachycardia‚ as a normal reaction to some type of excitement‚ anxiety‚ stress‚ or just exercise. There are two other types of tachycardia and those are named supraventricular tachycardia and ventricular tachycardia. The condition of tachycardia is caused by abnormal electrical impulses that control the heart. The main symptom of this syndrome is awareness of a rapid heartbeat that is commonly called “palpitations.” Depending on the cause and
