Discuss the definitions of ASD and VSD. What are the symptoms for each in children? What are the symptoms for each in adults? Briefly discuss treatment options for children and adults with ASD and VSD. Our text defines a murmur as a turbulent blood flow through the heart as a result of one or more etiologies (Cash, 2014). The abnormal opening through chambers, atrial or ventricular septal defect is the selected etiology appropriate for this discussion topic (Cash, 2014). During the first 8…

coronary artery disease, hypertension, cardiomyopathy, valvular disorders, renal dysfunction, ischemia and myocardial infarction. It can be systolic heart failure in which the heart muscles are weakened and results in decreased blood ejected from the ventricle,…

abnormal chamber openings (Weber & Kelley, 2014). The heart has four chambers two atria, which are the upper chambers of the heart and two ventricles, which are the lower chambers of the heart. They are then further divided into left and right. Between the upper and lower chambers there are valves to prevent backflow of blood. Between the right atrium and right ventricle tricuspid valve and between…

Premature Ventricular Contractions (Pvcs) Overview- Premature ventricular contractions (PVCs) are abnormal, extra heart-rates that initiate in ventricles, one of your heart's two lower pumping chambers. These additional pulsates disturb your normal heart musicality, in some cases making you feel a flip-flop or skipped beat in your chest. Premature ventricular contractions are extremely normal, mainly it occurs in most of the people at some time. If you are infected by ventricular constrictions,…

failure (CHF) occurs when the ventricles of your heart can’t pump blood sufficiently, causing fluid to build up not only around your heart but lungs, abdomen, and liver as well. There are multiple different types of CHF, the most common being left-sided which is when the left ventricle is weakened. Along with that, there are two separate types of left-sided CHF which are known as Systolic HF, where the ventricle fails to contract correctly and Diastolic HF, where the ventricle stiffens,…

Sinoatrial (SA) Node and its function is to send electrical impulses that stimulate your heart to beat, and these impulses induce the atria to contract. As the atria contract, the impulse moves on to the Atrioventricular (AV) node which leads the ventricles to contract (A). A pacemaker becomes necessary when the heart suffers from arrhythmia, a condition of irregular heartbeats, and is unable to contract at a rate deemed sufficient to meet the metabolic needs of the patient. Bradycardia is a…

to hydrocephalus it is taken very literally and seriously. Hydrocephalus is a condition in which cerebrospinal fluid accumulates in the brain, enlarging the head and causing brain damage (MedicineNet, 2016). Hydrocephalus can be a result of the ventricles producing too much cerebrospinal fluid. There can also be an obstruction which reduces the flow of cerebrospinal fluid, as well as inadequate absorption of the cerebrospinal fluid into the bloodstream (Boston Children 's Hospital, 2016).…

Hydrocephalus is a medical condition in which there is cerebrospinal fluid in the brain. This cause increases pressure inside the skull and may cause enlargement of the head if it occurs in the childhood, it can cause convulsions, mental disability and tunnel vision. It can also be called “Water on the brain.” Hydrocephalus can be inherited or acquired factors. This includes Spina Bifida, Craniosynostosis and Vein of Galen malformations. For acquired causes hemorrhage,head trauma,tumors and…

atrium. This produces a P wave on the EKG reading which is normally 0.1 second and its normal amplitude is 0.10-.012 mV. The AV node then causes a brief delayed of 0.1 second which allows the ventricles to relax and fill with blood. The AV node then transmits electrical signals from the atrium to the ventricles through the interventricular septum.…

An artificial heart is an invention that is saving many lives worldwide. The idea was created by Paul Winchell and later changes by Robert Jarvik. The artificial heart is ran by a pacemaker, and if only two chambers are working you will need an artificial heart pump. There are many risks and disadvantages to living and having an artificial heart. Making the heart is very complex and takes a while to make. Also in the medical field, artificial hearts are useful because they help people live…
