Ventricular septal defect

Syncope "Syncope is defined as an abrupt, transient loss of consciousness and postural tone with spontaneous recovery, most often caused by loss of cerebral oxygenation and perfusion referred to as cerebral ischemia. Syncope is also referred to as transient loss of consciousness (Grimes, 2014)." Syncope is considered the most common medical emergency in dental offices around the world (Grimes, 2014). It can most likely occur when blood pressure is too low (hypotension) and the heart is not…

later in life. A heart murmur is not a disease but can affect the cardiovascular system which may lead to heart problems. Anyone from infant to adults can have a heart murmur. Infants and children may need to have surgery due to atrial or ventricular septal defects. If you have an innocent heart murmur or an abnormal heart murmur you most likely will not have any other signs and symptoms other than the rhythm of your heart beat. If you have a heart…

Diagram the ventricular system. Be certain to include: the lateral ventricles, the 3rd and 4th ventricles, the cerebral aqueduct, and the central canal. Describe the purpose of the ventricular system. In your answer be certain to define components of this system that are more difficult the diagram; specifically Cerebral Spinal Fluid and Arachnoid granulations. (10 points) The ventricular system is made up of ventricles in the brain which contain…

In this paper you will find information about pacemakers and defibrillators. Pacemakers and defibrillators are devices that help keep the heart in rhythm. If the heart starts to beat to slow or to fast it will send an electrical shock to get it back on pace. When you get one or both devices implanted in you will need to have regular check-up with the doctors, these should not affect your daily life. Later on in the article you read that you may be allowed to still participate in fast paced…

A growing number of non-cardiac drugs have been found to delay cardiac repolarization, causing QT interval prolongation and predisposing patients to an increased risk of potentially fatal ventricular arrhythmias, known as torsade de pointes (TdP) (Letsas et al, 2007; Yap and Camm 2003; Sanguinetti and Tristani-Firouzi). These drugs include the second-generation, non-sedating antihistamines astemizole and terfenadine, withdrawn from the market in Europe and the United States (in 1997 and 1999,…

VASOVAGAL SYNCOPE 3 Vasovagal Syncope It starts with a feeling of whirling sensation, followed by blurred vision, and a muffled sense of hearing, until one unknowingly wakes up on the floor, wondering what had happened. This type of syncope is the classic movie scene when someone receives shocking news and passes out (Team, 2015). As scary as it is, this type of fainting is quite common in the United States. Vasovagal syncope is a result of a sudden drop in heart rate and blood…

The available technology points toward the use of lead/acid batteries to supply the power for ZEVs. The negative consequences associated with lead/acid batteries are numerous. For example, lead/acid batteries contain a large amount of lead. When the life of the battery is lost, the disposal of the lead within the battery must be dealt with appropriately. An analysis by researchers at Carnegie-Mellon found that the mass production of electric cars using lead/acid battery packs would exponentially…

Nanoparticles with Defects by Vladislav Ischenko,Sebastian Polarz,Dirk Grote,Victorina Sravarache,Karin Fink,and Matthias Driess. This paper discusses the importance of a nanoscale ZnO with defects in its structure. The article also provides a broad analysis of ZnO nanoparticles using a consolidation of techniques and the resulting data is summarised in this review. The paper gives the realization of when a nanocrystalline ZnO that is rich in defects could be obtained. The types of defects and…

is the most common type of birth defect. CHD causes more deaths in the first year of life than any other birth defects. There are many causes of CHD including problems with genes or chromosomes in the child, taking certain medications, drugs, or alcohol during pregnancy,and a viral infection, like rubella in the mother, in the first trimester or pregnancy. All of these things can cause your baby's heart to malfunction. Heart defects are the most common type of defect babies are born with,…

braces or surgery later in life; which could change the way they speak. According to the children’s heart foundation “ Approximately 40,000 babies are born each year in the United States with CHD” ( CHF, par. 1). What is CHD? CHD is congenital heart defect; meaning babies are born with an abnormally obstructed heart and/ or large vessels within the heart. Pediatric…
