Introduction to Atrial Fibrillation
The most prevalent clinical arrhythmia is atrial fibrillation, which can be defined as irregular heart beats caused by uncoordinated activation of the atria. Atria are the two upper chambers of the heart. During atrial fibrillation, the cardiac muscles that make up the walls of these atrial chambers, receive disorganized activation signals. This causes them to fibrillate, which means rapid and irregular contractions. This results in inefficient pumping of blood from the atria into the ventricles, the lower two chambers. In some cases, people do not suffer any symptoms, but there is still a higher risk of stroke in patients with signs of atrial fibrillation. The common symptoms of atrial fibrillation include

Metabolism seems linked to rapid or irregular heart beats that is seen in atrial fibrillation and its development has been seen in patients with thyroid gland disorder, hyperthyroidism, in which an excess of thyroid hormone is produced, with signs of fast heartbeats.
Atrial fibrillation are commonly associated with different cardiovascular diseases, or may not be linked to any heart disorders at all. The progress of atrial fibrillation has been linked to the following cardiovascular disorders: coronary artery disease, pericarditis, congenital heart disease, problems with valves: mitral stenosis and mitral regurgitation. Also, there are myocardial enlargements that are associated with atrial fibrillation including hypertrophic cardiomyopathy and left atrial enlargement.[2] High blood pressure as well as earlier heart surgeries have also been linked to atrial fibrillation.
In some cases, lung diseases have been thought to be involved in the development of atrial fibrillation for example lung cancer, sarcoidosis, pneumonia and pulmonary embolism, as well as breathing problems associated with sleeping
Cardiac murmurs can be present at birth (congenital; often caused by malformations) or acquired and manifests later in the animals life. (Ex: disease of the cardiac muscles, disease of the cardiac valves, etc.). It is important to note that many animals with heart murmurs can live a long and happy life without
Breathing can be cause by spinal deformities. In the joint instability, dislocations would lead a person to roll over in bed and turning a doorknob. Cardiovascular problems affect by prognosis and life. There are issues of all different types of EDS, the person will have better life. The difficulties of blood vessel fragility can lead a risk.
Normally, low-oxygen blood entering the right side of the heart stays on the right side, and subsequently oxygen-rich blood stays on the left side of the heart, where it is then pumped to the body and tissues. When a defect or "hole" is present between the atria (or upper chambers of heart), some oxygen-rich blood leaks back to the right side of the heart. It then goes back to the lungs even though it is already rich enough in oxygen. Because of this, there is a significant increase in the blood that goes to the lungs overall. Atrial septal defects can
Generate: Heart auscultation is useful in characterizing heart sounds and identifying abnormalities that may suggest cardiac dysfunction.1 The fourth heart sound (S4 atrial gallop), heard during the patient’s physical examination, is often an abnormal finding due to reduction in ventricular wall compliance.1,2 Additionally, S4 occurs due to rapid deceleration of active blood flow due to a nondistensible ventricle.2 S4 can be heard in patients with hypertension, hypertrophic cardiomyopathy and acute myocardial infarction (AMI).1,2

Damaged heart valves, toxic exposure, such as alcohol, prolonged arrhythmias, and infections are all other causes
There are many things that can be done in order to manage atrial fibrillation such as undergoing certain procedures and taking certain medicine. With atrial fibrillation the medicine can be taken to aid with controlling the heart rate and preventing blood clots. The medication that can be used for this is amiodarone and Propafenone because they are antiarrhythmic. Antiarrhythmic drugs are use help with arrhythmias (irregular heartbeats) in the heart. Amiodarone is a group three antiarrhythmic drug which means that it works by blocking the potassium channels which then slows down the cells ability to repolarize but it has properties of all four type of antiarrhythmic.
The dilation of the blood vessels will increase the demand for oxygen which then will cause the respiratory system to raise the respiration rate in order to bring in more oxygen which then results to shortness of breath (SOB). Also, the change in the blood vessels will be picked up by the stretch receptors in the heart which will cause the heart to beat with more pressure and to beat faster. Although these common are seen through many Atrial Fibrillation patients. A variety of patients with Atrial Fibrillation doesn’t experience any of the symptoms that are listed above. These patients just tend to show no symptoms of Atrial Fibrillations until they undergo a variety of tests and procedures that is used in order for a patient to be diagnose with Atrial
Atrial fibrillation (AF) is an important risk factor for ischemic stroke. AF increases the risk of stroke five fold and contributes to at least 15% of all strokes. Therefore, stroke prevention with the use of antithrombotic therapy is central to the overall management strategy of patients with AF. The first factor to consider is stroke risk assessment. The CHADS2 or CHA2DS2-VASc risk stratification method is used to direct the treatment of patients with AF by assessing a patient’s risk for stroke.
It increases the risk of a stroke and heart attack. AFib can be caused by heart abnormalities, adrenaline inducing medication, or alcohol. When beating rapidly the heart can beat up to six hundred beats per minute! With every year a person with AFib grows, so does the chance of a stroke. The first step in curing AFib is to identify what he cause is.
The existence of cardiomyopathy was first proposed by Rubler et al, In 1974 Framingham study showed that heart failure was more common in diabetes due to diabetes cardiomyopathy.58,59 The Framingham heart study reveals a marked in congestive heart failure, coronary artery disease and myocardial infarction in diabetes patients.60 Diastole is that phase of the of the cardiac cycle when the heart is not contracting to propel blood out (systole) to the body, brain and lungs but instead is relaxing and filling with incoming blood that is being return from body through inferior vena cava from lungs through the pulmonary veins and the through superior vena cava. Diastole begins with aortic valve closure and ends with mitral valve closure. Diastole
When I pressed the doctor for more understanding on how that would cause they symptoms I have she explained that on the mitochondrial level things were plugged up and not operating effectively and that my heart was having symptoms as it had a much
Marfan 's Syndrome is a heritable disorder of the connective tissue. It affects many body systems, like the lungs, skeleton, heart, eyes, and arteries. These parts affected may sound like they are unrelated but they are all affected by a mutation in a single gene on Chromosome 15. This gene is named FBN1 for the protein it encodes, fibrillin-1. What causes this mutation is the amino acids that builds proteins mix up a certain code on each protein and it makes the wrong amino acids that are put on the proteins.
What is it?- A pacemaker is a small device that 's placed in the chest or abdomen to help control abnormal heart rhythms. This device uses low-energy electrical pulses to prompt the heart to beat at a normal rate. Pacemakers are used to treat arrhythmias. Arrhythmias are problems with the rate or rhythm of the heartbeat. What is the history of pacemaker-pacemaker use electrical impulses to regulate the beating of the heart.
• Hypertension – High blood pressure has consistently been associated with an increased risk of developing an acute MI. • Smoking – Tobacco contains certain components that are known to damage vessel walls. The body’s response to this damage elicits the formation of atherosclerosis thereby increasing the risk of an acute MI. • Male gender – The incidence of developing an acute MI is more for men than women however; with age this risk
