Cardiac arrhythmias are disturbances in the normal rhythm of the heart. They may present as very fast, very slow or irregular heartbeats. One of the most frequent and relevant is the atrial fibrillation<\/strong>which increases the risk of stroke by up to five times. In this article you will learn how to identify them, their main causes, and the treatment options available at Puerto Vallarta<\/strong>.<\/p>\n\n\n\n

What is a cardiac arrhythmia?<\/h2>\n\n\n\n

An arrhythmia is any change in the sequence of heartbeats that causes the heart to beat too fast (tachycardia<\/em>), too slow (bradycardia<\/em>) or irregularly shaped.
The heart has an internal electrical system that coordinates its contractions. When this system is disturbed, abnormal rhythms appear, which may be temporary or persistent.<\/p>\n\n\n\n

Atrial fibrillation: the most common arrhythmia<\/h2>\n\n\n\n

Atrial fibrillation occurs when the atria (upper chambers of the heart) beat in a rapid and disorganized manner, preventing efficient contraction. This can cause blood to pool and form clots, which when dislodged may travel to the brain and cause a stroke<\/strong>.<\/p>\n\n\n\n
