Freedman et al. (2016) discussed that from a meta-analysis of five studies, the researcher concluded that a vitamin K antagonist such as warfarin can reduce stroke by up to 64% and mortality by 26% when compared with a placebo. To be able to prevent stroke related to a-fib the first step is to complete a stroke risk stratification using assessment tool such as the CHA2DS2-VASc. The chad score can help determine if anticoagulation therapy is recommended base of risk factors such has any congestive heart failure, hypertension, patient age, diabetes, prior stroke, vascular disease, and the sex of the patient. If patients are on an OAC, provider need to monitor closely the international normalized ratio.…
In the United States, people suffer from heart problems every day. According to the Centers of Disease Control and Prevention (CDC), every year about 935,000 people in the United States suffer from a heart attack and about 600,000 die from heart problems. Electrocardiograms (EKG or ECG) provide important information concerning the electrical activity of the heart as well as the quantity and quality of heart contractions. An EKG, along with blood work to measure troponin levels, can definitively determine whether or not a person has suffered from a myocardial infarction. In order to obtain an EKG, electrodes are strategically placed on the limbs and torso of a subject to measure the electrical current that is generated in the heart and transferred to the skin. The electrical signal is first generated in the sinoatrial node (SA node). It then travels to both the left and right atria to cause them to contract. Then, the signal goes to the atrioventricular node (AV node) where it is briefly delayed to allow all of the blood from the atria to move into the ventricles. It then moves through the Bundle of His toward the apex of the heart and then through the Purkinje fibers. This causes contraction of the ventricles to pump blood throughout the body and lungs. The purpose of this lab was to compare EKG at rest with and exercising EKG. In doing so, the subject’s heart health could be determined based on the results of being put under the stress of exercise versus when resting.…
As of 2011, there were 3 million people affected by atrial fibrillation with that number expected to increase by 2.5 fold by 2050. The cost of atrial fibrillation is more than $6 billion per year. With numbers like these, it is surprising that there is not a greater amount of research concerning this topic. The study addresses the problem of limited information concerning first-hand information from patients living with atrial fibrillation as demonstrated in the review of literature within the article. The point is made that though conditions such as myocardial infarction, coronary artery disease, and heart failure fall within the same rhelm as atrial fibrillation, this problem is unique to those living with it and deserves to be studied further (McCabe, Schumacher, & Barnason,…
Have an electrocardiogram (ECG) to evaluate your heart’s rhythm and look for abnormalities in the heart’s electrical system(cardiosmart,2013).…
2.3.e. What is an EKG? 2.3.f. How can an EKG be used in the diagnosis and treatment of heart disease? EKGs, or electrocardiographs (“electricity heart pictures”) measure the heart’s electrical activity and display it in the form of a picture: P wavesignal passes from SA node (sinoatrial node) to AV node (atrioventricular node), moving across atria QRS intervalsignal passes from AV node through Purkinje fibers & the ventricles contract T wavethe ventricles repolarize & the heart is relaxed…
Aging heart, is characterized by myocardial fibrosis and atrial dilation, which is a proper soil for AF to flourish. Atrial Fibrillation creates electrical and structural remodeling in the atria by shortening, mismatching, and lengthening the effective refractory period (increase of dispersion), depressing the intra-atrial conduction, and depriving its contractile function (Karamichalakis,& Letsas). Because A-Fib cases increase with age and women generally live longer than men, more women than men experience AFib as Center for Disease Control (CDC) shows in her Fact sheet.…
Antiarrhythmic drugs; these drugs control heart rate and include beta-blockers. Anticoagulant or antiplatelet therapy; these drugs reduce the risk of blood clots and stroke, these include warfarin or aspirin. Another blood thinner called Pradaxa (dabigatran) was approved in 2010 to prevent stroke in people with atrial fibrillation. Because everyone is different, it may take trials of several medications and doses to find the one that works best for…
This condition is diagnosed based on the description of your symptom. Your health care provider may performa a physical exam to listen to your heart. Your health care provider may also perform tests to rule out other conditions. These tests may include an electrical tracing of your heart called electrocardiogram (ECG). If you have this test, you may need to wear a portable ECG machine (Holter monitor) that records your heart beats for 24 hours or more.…
Since 1932, cardiac arrhythmias have been treated by the use of pacemakers. According to the article, “The Evolution of Pacemakers”, “An artificial pacemaker is a device that delivers a controlled, rhythmic electric stimulus to the heart muscle in order to maintain an effective cardiac rhythm for long periods of time” (Sandro A.P. Haddad, 2006). In the earliest stages, pacemakers were quite primitive but evolved to become much more practical in size, weight and mobility.…

Diagnosing for arrhythmia, what happens to begin with, is the specialist's first take a gander at your history to check whether it could really be feasible for you to have this. They generally search for coronary illness, hypertension, ailment, and wellbeing issues. At that point in the wake of looking over your history they do a physical exam. Nothing excessively distinctive when they do a physical exam, specialist's simply listen to your heart beat and mood to hear if…
