3 days ago · 315,000 with atrial flutter (2019) [10] Atrial fibrillation ( AF, AFib or A-fib) is an abnormal heart rhythm (arrhythmia) characterized by rapid and irregular beating of the atrial chambers of the heart. [11] [12] It often begins as short periods of abnormal beating, which become longer or continuous over time. [4]

May 15, 2024 · What it is. Atrial fibrillation, often called AFib or AF, is the most common type of treated heart arrhythmia. An arrhythmia is when the heart beats too slowly, too fast, or in an irregular way. When a person has AFib, the normal beating in the upper chambers of the heart (the two atria) is irregular, and blood doesn't flow as well as it should ...
May 26, 2024 · The heart is a muscular organ found in most animals. This organ pumps blood through the blood vessels of the circulatory system. [1] The pumped blood carries oxygen and nutrients to the body, while carrying metabolic waste such as carbon dioxide to the lungs. [2]
4 days ago · Cardiology is a branch of medicine that deals with disorders of the heart and the cardiovascular system. The field includes medical diagnosis and treatment of congenital heart defects, coronary artery disease, heart failure, valvular heart disease, and electrophysiology.
May 9, 2024 · In normal sinus rhythm, the P-P interval (the time between consecutive P waves) is the same throughout the ECG. Also, the heart rate (how fast the heart is beating) is between 60 and 100 beats per minute, and the P waves are the same shape throughout. In sinus arrhythmia, the P-P interval is slightly varied by 120 milliseconds or more.

2 days ago · A number of exploratory studies examined other ECG indices as risk stratifiers. Yap and associates (St. George's Hospital Medical School, London, United Kingdom) examined the changes in heart rate after a premature ventricular contraction (PVC) (termed "heart turbulence"). They showed that the normal cardiac slowing followed by acceleration ...

May 25, 2024 · bradycardia, type of arrhythmia (abnormal heart rhythm) characterized by slowing of the heart rate to 60 beats per minute or less. A slow heart rate in itself may have little medical significance; bradycardia is frequent among young adults, especially in highly trained athletes or during sleep. However, bradycardia may indicate significant ...
