    An arrhythmia is a heart rhythm that isn’t normal*. Some common examples include the heart beating too fast when you’re at rest or not beating in a regular pattern. Arrhythmias can range from harmless to serious, with or without symptoms. There are several options to treat arrhythmias, but not all people with arrhythmias require treatment.
    An arrhythmia is an abnormal heartbeat (**note: the term "arrhythmia" refers to any change from the normal sequence of electrical impulses in the heart**). Some arrhythmias are brief and do not significantly affect the overall heart rate or rhythm.
    Arrhythmias can be caused by changes to heart tissue, such as damage or stiffening, which can alter the normal electrical signals that control the heartbeat. This can result in an irregular heart rhythm. Other causes include a delay or blockage of the electrical signals and another part of the heart taking over as pacemaker. Excessive exertion, strain, or stress can also contribute to arrhythmias.
    The prognosis for arrhythmia varies greatly depending on the type. Arrhythmias range from harmless to serious, with symptoms and without. What is important to note is that some people with arrhythmias don’t need treatment. The passage goes on to describe arrhythmia as a condition that disrupts the normal heartbeat signals.
