What is the most common type of arrhythmia?

Atrial fibrillation is recognized as the most common type of arrhythmia and is a significant health concern due to its prevalence and potential complications. This condition often leads to an irregular and often rapid heart rate, which can increase the risk of stroke and other heart-related issues.

Atrial fibrillation affects millions of people worldwide and is particularly common in older adults, those with hypertension, and individuals with certain underlying heart diseases. The disorganized electrical signals in the atria result in ineffective contraction, leading to issues with blood flow and the potential for thrombus formation in the heart.

Understanding the mechanisms and implications of atrial fibrillation is crucial in cardiovascular practice, as management strategies often focus on controlling heart rate, restoring normal rhythm, and preventing thromboembolic events. Thus, it is not only the frequency of occurrence that qualifies atrial fibrillation as the most common arrhythmia but also the clinical significance related to patient outcomes.
