Atrial Fibrillation Case Studies

311 Words2 Pages

Since Atrial Fibrillation (AFib) is an arrhythmia (irregular heartbeat) the symptoms are very similar to that of a heart attack. Such as angina pectoris (chest pain), shortness of breath (SOB), irregular pulse, feeling tired and weak, fast heart rate, and quivering feeling in chest. Chest pain occur due to the fact that the heart is having many extra activities within the atrium and that the myocardium (muscles in the heart) in not receiving oxygenated blood because it is not being delivered. Which then causes the rest of the body to become fatigue due to the lack of oxygen the organs are receiving. When low level of oxygen is picked up by the chemoreceptors (special cells that notes the level of oxygen and carbon dioxide) and it signals the medulla oblongata which controls the breathing rate and the heart rate. …show more content…

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

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.

Milton Larsen Case Summary

946 Words | 4 Pages

Presented is Milton Larsen, a 84 year-old African American veteran who lives with his step-daughter Dina in a small home. Mr. Larsen’s bedroom is located in the basement, where he spends most of his time with his cat Snuggles. The objective data gathered from Milton Larsen’s case scenario is as followed: a medical diagnosis of hypertension and left knee osteoarthritis. He is prescribed metoprolol tartrate and spironolactone for his hypertension and he takes ibuprofen for aggravation of the left knee related to frequent trips to the upstairs bathroom. At a recent visit to his primary care physician Milton Larsen stated the following subjective data “Dina gets mad at my cat and takes it out on me.”

Amiodarone Study

Figure 1 shows the electrocardiogram (ECG) after the angiography. A carotid endarterectomy was performed 5 months before due to an atheroembolic stroke. During the postoperative period, she presented atrial fibrillation with rapid ventricular response and amiodarone was added to her habitual treatment. Her current treatment is ASA 325 mg/day, atenolol 50 mg bid, enalapril 20 mg bid and amiodarone 200 mg bid. One month before the event she attended the outpatient clinic and an echocardiogram was performed, which showed: normal left ventricular dimensions, wall thickness mildly increased, normal left atrium and aorta, mild left ventricular dysfunction with an estimated ejection fraction of 50%, hypokinetic basal inferior and mid inferior segments and mitral inflow filling pattern of delayed relaxation (according to her age).

Abraham Lincoln Marfan Syndrome

The lung tissues may develop a pneumothorax. This causes the lungs to collapse by letting air escape into the chest cavity. This disease may affect the heart through aortic dilation. The aorta is a blood vessel that is responsible for transporting blood from the heart to the body. In aortic dilation, the aorta may overstretch or become weak.

2.Heart failure symptoms can include shortness of breath while sleeping or walking. Symptoms can show signs of chest pain or anxiety from stress. There are multiple signs and symptoms a person should look out for, such as dizziness, fatigue, rapid irregular heartbeat, or even swelling in the ankles, legs, and feet. But, in some cases there may be no symptoms at all. 3.Heart Failure can affect anyone of age, including infants, toddlers, children, teens, adults, and the elderly.

Valley Fever (Coccidioidomycosis) Overview- Coccidioidomycosis, or valley fever is a fungal infection caused by Coccidioides immitis spores. Mild cases of this condition are not common and treatment is not generally necessary. However, this disease is often misdiagnosed, due to the fact that you experience only mild or moderate symptoms, and these symptoms often takes 20 years to present. The most severe cases of Coccidioidomycosis causing the infection to spread to other parts of the body through the bloodstream, and people with compromised immune systems are at greatest risk. -causa

Explanations For Afib Treatments

545 Words | 3 Pages

AFib treatment options vary depending upon the severity of the disease and the underlying reasons or diseases that caused it to occur. Atrial fibrillation, also known as AFib, must be treated on a case-by-case basis in order to reduce the risk of other health problems or complications. Understanding AFib AFib occurs when the uppermost chambers of the heart beat irregualry and uncoordinated with the lower two chambers. AFib often causes a fast heartbeat that is irregular, chest pain, difficulty breathing, heart palpitations, weakness and dizziness. AFib episodes may happen sporadically or become chronic and occur regularly.

Autonomic Nervous System Case Study

Thus, the sympathetic nervous system increases heart rate, and the forced contractions widen the airways making it easier to breathe. Your body now releases stored energy, which allows for increased strength in muscles, and can also cause your palms to sweat, pupils to dilate, and hair to stand up. The parasympathetic division is most active during resting conditions, hence, why it can also be called, “rest and digest”. This division controls body processes during ordinary situations. It generally slows down your heart rate and decreases your blood

The pain started while he was shoveling snow from his walkway. He had experienced chest discomfort with activity previously, but the pain had subsided with rest and he sought no medical help. This time the pain did not subside and became increasingly severe, radiating to his left arm and lower jaw. In the emergency department, an ECG and cardiac enzymes were obtained.

Case Study Cardiogenic Shock

1075 Words | 5 Pages

This type of shock occurs when the heart is unable to pump blood effectively. This is evident to patients who have had myocardial infarction, such as John’s case. In this illness, the heart has decreased contractility resulting to decreased cardiac output. Such decrease will stimulate the sympathetic nervous system to activate the compensatory mechanism by increasing the heart rate as evident in John’s vital sign to increase the peripheral pressure and ventricular

Total Lung Capacity Essay

785 Words | 4 Pages

The heart may have the sinoatrial node (SA node) to trigger contraction, but in order for us to breath our nervous system has to signal for us to begin the process of ventilation (breathing). Our brain stem has three parts to it, but only the pons and medulla oblongata play a key role in breathing. The medulla helps set the respiratory rhythm by receiving and sending impulses to a bundle of neurons called the ventral respiratory group to the phrenic nerve to bring about contraction in the diaphragm and external intercostal muscles. All this only happens though due to the sensors of the chemoreceptors. The chemoreceptors located in the medulla and carotid and aortic bodies detect a rise in carbon dioxide (CO2).
