The heart has four chambers, two upper chambers—the right and left atrium, and two lower chambers—the right and left ventricles. Fibrillation describes when the muscle fibers are all contracting at different times, so the end result is this quivering, or twitching movement.
Generally, diseases outlined within the ICD-10 codes G40-G47 within Chapter VI: Diseases of the nervous system should be included in this category. Subcategories This category has the following 4 subcategories, out of 4 total.
Atrial fibrillation is associated with an increased risk of heart failure, dementia, and stroke. [3] [12] It is a type of supraventricular tachycardia. [14] Atrial fibrillation frequently results from bursts of tachycardia that originate in muscle bundles extending from the atrium to the pulmonary veins. [15]
There are two major classes of cardiac fibrillation: atrial fibrillation and ventricular fibrillation. Atrial fibrillation is an irregular and uncoordinated contraction of the cardiac muscle of atria. It can be a chronic condition, usually treated with anticoagulation and sometimes with conversion to normal sinus rhythm.
Aortic regurgitation (AR), also known as aortic insufficiency (AI), is the leaking of the aortic valve of the heart that causes blood to flow in the reverse direction during ventricular diastole, from the aorta into the left ventricle.
Paroxysmal nocturnal dyspnea is a common symptom of several heart conditions such as heart failure with preserved ejection fraction, in addition to asthma, chronic obstructive pulmonary disease, and sleep apnea. [8] Other symptoms that may be seen alongside paroxysmal nocturnal dyspnea are weakness, orthopnea, edema, fatigue, and dyspnea. [9]
The person may, in fact, have too little fluid in their blood vessels, but if the low blood pressure is due to cardiogenic shock, the administration of additional fluid may worsen the heart failure and associated low blood pressure. If the person's circulatory volume is adequate but there is persistent evidence of inadequate end-organ perfusion ...
Catheter ablation is a procedure that uses radio-frequency energy or other sources to terminate or modify a faulty electrical pathway from sections of the heart of those who are prone to developing cardiac arrhythmias such as atrial fibrillation, atrial flutter and Wolff-Parkinson-White syndrome.
