Given what we know about anatomy, we can confirm that atrial flutter is the option listed that may not be considered an arrhythmia.
What is an arrhythmia?
- An arrhythmia is classified as an irregular beating of the heart.
- What this means is that the heart will beat at rhythms different from the normal.
- A normal heartbeat can increase or decrease in speed, but as long as the beating follows a regular rhythm it is not considered an arrhythmia
- The atrial flutter can cause the heart to beat much faster than normal but maintains a regularity.
Therefore, since the atrial flutter causes the heart to beat very fast, but maintains a regularity to it, we can confirm that this is not a type of arrhythmia given that an arrhythmia is classified as an irregular beating of the heart.
