Cardiovascular System, Research Paper Example

Research Paper

The human cardiovascular system possesses a critical function in the body to provide blood to all organs and systems to sustain living. Therefore, the heart serves as the driver for this system, and is responsible for pumping blood to these organs through different vessels that are located throughout the body. The pumping action of the heart is essential to the effective functioning of the human body and its systems, and therefore, must be healthy and strong as best as possible. The heart is comprised of four chambers, two atria and two ventricles, each of which plays an important role in transporting blood through the arteries throughout different parts of the body (InnerBody, 2004).  As the blood circulates, it is carried away from the heart through these arteries and carried back to the heart through veins, which are comprised of a different thickness and consistency than arteries (InnerBody, 2004).  When the heart does not pump blood properly for any reason, it is possible to identify different causes or conditions, which may include irregular heartbeat patterns. These patterns are diverse, and are typically known as arrhythmias (MedicineNet.com, 2010). These arrhythmias are identified based upon the type of heartbeat activity that is observed through different testing procedures, such as Electrocardiograms (MedicineNet.com, 2010). Some of the most common arrhythmias are as follows: 1) Premature ventricular contractions, which are known as “skipped” heartbeats; 2) Atrial flutter, which is caused by electrical malfunctions in the atrium; 3) Atrial fibrillation, which leads the atria to contract in an ineffective manner; and 4) Bradyarrhythmia, which is associated with slower heartbeats that are caused by electrical malfunctions (MedicineNet.com, 2010).

There are a wide variety of symptoms that may lead to a diagnosis of arrhythmia, such as heart palpitations, chest pain, and shortness of breath, amongst others, and these symptoms are different in each individual case (MedicineNet.com, 2010). In order to diagnose these arrhythmias effectively, different types of tests are typically conducted that are designed to examine the level of heart activity that is taking place during a given period of time (MedicineNet.com, 2010). For example, the electrocardiogram, stress test, Holter Monitor, and Echocardiogram are tests that are commonly used to diagnose arrhythmias in patients of all ages (MedicineNet.com, 2010). Each of these tests is effective for different reasons, and may lead to a definitive diagnosis regarding an arrhythmia and how to treat the condition (MedicineNet.com, 2010). It is necessary to pursue these tests when a possible diagnosis of an arrhythmia is made so that proper treatment, if required, is pursued in a timely manner (MedicineNet.com, 2010). In many cases, no additional treatment is required, but in other cases, a combination of medication and/or possible surgical interventions are necessary in order to achieve the desired results and to maintain healthy living (MedicineNet.com, 2010). Furthermore, for patients that suffer from arrhythmias, it is often necessary to make changes to their lifestyles that are suitable for the given condition, such as reduced caffeine intake, quitting smoking, improved diet and exercise, and improved sleeping habits, amongst others (MedicineNet.com, 2010). Each of these factors is representative of an opportunity to improve overall health and well being, despite the condition, regardless of its severity (MedicineNet.com, 2010).
