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 …show more content…

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

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.

Heart Auscultation Case Summary

455 Words | 2 Pages

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

Annex 1 Heart Murmur

951 Words | 4 Pages

Annexe 1 : Heart murmur 1. An unusual sound coming from the heart that can be detected by a stethoscope. These noises are caused by an abnormal turbulence produced when blood flows across one of the heart (valves, cardiac chambers) and or vessels close to the heart Heart murmurs are classified by the intensity of the sound heard: Stage I (murmur is of low intensity and can hardly be heard) to Stage VI (murmur is extremely loud).

Atrial Septal Defect Essay

1039 Words | 5 Pages

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

Cardiomyopathy: Framingham Heart Study

Left atrial enlargement with associated AF provides an easily identifiable indicator of LVDD and need for further echocardiography evaluation. 1- Trans mitral flow velocity: the early diastolic peak filling velocity when the transmitral pressure gradient is greatest generates the E wave velocity on the echocardiography. The late diastolic peak filling velocity associated with atrial contractions generates the A wave velocity. Because normal atrial contribution to total to total diastolic filling is only 30%, a normal A wave is smaller than E wave with a ratio >1.

Write An Essay On Supraventricular Tachycardia

1603 Words | 7 Pages

Supraventricular Tachycardia Narrow complex tachycardias are defined by the presence in the electrocardiogram of a QRS complex with less than 120 msec duration and a heart rate more than 100 beats per minute. They are usually of supraventricular origin, though narrow complex ventricular tachycardias were rarely reported in the literature (Hayes et al, 1991). Supraventricular origin of the tachycardia means the obligatory involvement of one or more of the cardiac structures above bifurcation of His bundle. Those include the atrial myocardium, the AV node, the proximal His bundle, the coronary sinus, the pulmonary veins, the venae cavae, or abnormal atrio-ventricular connections, namely bypass tracts (Lau, 2008). Although pharmacologic treatment is still in use for suppression and treatment of SVTs, particularly for atrial arrhythmias, reported efficacy and side effects limited their application.

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.

Marfan Syndrome Essay

553 Words | 3 Pages

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.

The natural pacemakers of the heart called SA (Sino-atrial) node. SA is in the grooves where the superior vena cava meets the right atrium. After SA generates electrical signals, the cardiac impulse travels across the walls of the atria causing the atria to contract. The impulses generated by the SA node are also transmitted to the atrioventricular (AV) node located in the lower part of the right atrium near the right ventricle. When the electrical signals reach the ventricle walls from pacemakers, ventricles contract and builds up the pressure which pushes blood and opens semilunar valves.

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.
