Both the right and left atrium contract causing blood to flow though the two valves, and then into the left ventricle. The left ventricle pumps blood into the systemic circulation through the aorta. This systemic circulation system is much bigger than the pulmonary circulation system, which is why the left ventricle is so big. The blood on the left side of the heart is oxygenated. It becomes oxygenated when the deoxygenated blood passes through the right atrium and then flows into the left ventricle. It is then pumped along the pulmonary artery into the lungs where it is oxygenated. It then travels through the pulmonary veins back into the heart. It enters through the left atrium and then travels to the left ventricle. This process is repeated over and over again, to make blood continuously flow through the heart, lungs and body. This process ensures that there is always enough oxygen for the body to work

Likewise, Blood flows from the right atrium to the right ventricle, and then is pumped to the lungs to receive oxygen. From the lungs, the blood flows to the left atrium, then to the left ventricle, forming the complete circulation.

Arrhythmias are irregular rhythms of the heartbeat which can be fast paced or slow paced.

Most physicians and people who acquired the problem usually know it as A-FIB, a shorter term for atrial fibrillation. Atrial fibrillation deals with the cardiovascular system, in particular, the heart in the body. It is defined as, “the electrical signals that control this system are off-kilter. Instead of working together the atria do their own thing, causing fast fluttering heartbeat, also known as arrhythmia” (WEBMD). In a normal pumping blood of the heart the atria would squeeze first, followed by the ventricles of the heart. A-fib can be a serious issue if not treated, due to the inadequate pumping of the blood, causing a higher chance of heart failure. It is also a higher chance in getting a stroke, because improper flow of the blood can cause clots in the

In a normal human being the heart correctly functions by the blood first entering through the right atrium from the superior and inferior vena cava. This blood flow continues through the right atrioventricular valve into the right ventricle. The right ventricle contracts forcing the pulmonary valve to open leading blood flow through the pulmonary valve and into the pulmonary trunk. Blood is then distributed from the right and left pulmonary arteries to the lungs, where carbon dioxide is unloaded and oxygen is loaded into the blood. The blood is returned from the lungs to the left

The oxygen rich blood returns from the lungs and it goes through the pulmonary vein to the left atrium.

First the de-originated blood goes into the right atrium. And the originated blood goes through the left atrium. The right atrium then pumps blood through the tricuspid valve into the right ventricle, and the left atrium pumps blood through the bicuspid valve into the left ventricle. The right ventricle contracts, semi lunar valve opens and deoxygenated blood travels back to the lungs. The left ventricle contracts, semi lunar valve opens and oxygenated blood goes out to the body.

The right atrium is where the process begins. Then, blood travels through the tricuspid valve to the right ventricle, and from there to the pulmonary artery. Once the blood travels through the pulmonary artery, it reaches the lungs. While in the lungs, the blood goes through a gas exchange: deoxygenated blood gets oxygenated (The gas exchange takes place in the alveoli, which are tiny air sacs in the bottom of the lungs

Monitor for signs and symptoms of dizziness or lightheadedness. Rationale: Prazosin lowers blood pressure which can make him/her feel dizzy.

It is also related that the oral and inhaled long-acting beta2 agonists are used for maintenance therapy. However, systemic or parental and oral are contraindicate for high-risk patients with tachycardia associated with digitalis toxicity, diabetes, hyperthyroidism, organic heart disease, hypertension or angina pectoris.

ACTIONS AND USESNifedipine is CCB generally prescribed for HTN and variant or vasospastic angina. It is occasionally used to treat Raynaud's phenomenon and hypertrophic cardiomyopathy. Nifedipine acts by selectively bloking calcium channels in myocardial and vascular smooth muscle, including those in the coronary arteries. This results in less oxygen utilization by the heart, an increase in cardiac output, and a fall in blood pressure. It is available as extended-release tablets (XL).

ACE inhibitors such as Captopril block activity of the enzyme ACE and therefore the conversion of angiotensin I to angiotensin II (the most bio active product of the RAAS), thus inhibiting the actions of angiotensin II and leading to decreased aldosterone production, decrease blood volume and reduced hypertension. ACE inhibitors also work to decrease fibroblast activity as a protective measure against remodelling of the left ventricle (19). Side effects of ACE inhibitors include a dry cough due to the inhibition of bradykinin break down, hypotension and hyperkalemia (due to higher levels of potassium reuptake). ACE inhibitors are currently one of the drugs of choice to treat patients with HF.

Today millions of Americans live or have lived with Atrial fibrillation. The main concern with this health issue is that many people who lived with it sometimes are not aware of it. Atrial fibrillation is defined by Mayo Clinic (2012) as “an irregular and often rapid heart rate that commonly causes poor blood flow to the body”. It occurs when the four chambers of the heart have a disrupted rhythm. The abnormal functionality of health may lead to a stroke because of the possible blood clot that will be formed. The Atrial fibrillation or Afib put the body in a situation without oxygen and nutrients because the body is not well supplied by a heart that is became weak. In general, only few people will feel change in their heartbeat. They may verbalize

According to Medscape, the 2013 updated JNC 8 guidelines recommend the first line of pharmaceutical treatment with combination therapy of thiazide-type diuretics along with angiotensin converting enzyme inhibitors (ACE), angiotensin receptor blockers (ARB), or calcium channel blockers (CCB).

This oxygen-rich blood comes back to the left atrium of the heart through the pulmonary veins. The blood passes through the mitral valve into the left ventricle which pumps the blood out through the aortic valve into the aorta. This is the main artery that takes this oxygen-rich blood to all the different parts of the body. Once the body has used all the oxygen from the blood, it is pumped back into the right side of the heart, and the process continues.
