Atrial tachycardia is a type of arrhythmia where the upper chambers of the heart beat faster than normal.
Understanding Atrial Tachycardia
Atrial tachycardia is a form of supraventricular tachycardia (SVT), an irregular heart rhythm. When someone experiences atrial tachycardia, the atria (upper chambers) of the heart beat rapidly, typically between 100 and 250 beats per minute. This is much faster than the normal heart rate, which usually ranges from 60 to 100 beats per minute.
Key Features of Atrial Tachycardia:
- Arrhythmia: An irregular heart rhythm.
- Rapid Heart Rate: Atria beat between 100 to 250 beats per minute.
- Location: Originates in the atria (upper chambers of the heart).
- Type of SVT: A specific type of supraventricular tachycardia.
Comparison Table
Feature | Atrial Tachycardia | Normal Heart Rate |
---|---|---|
Heart Rhythm | Irregular (Arrhythmia) | Regular |
Heart Rate (Atria) | 100-250 beats per minute | 60-100 beats per minute |
Location of Origin | Atria (Upper chambers of the heart) | Sinoatrial (SA) node in the right atrium |
In essence, atrial tachycardia disrupts the normal electrical signals in the heart, causing the atria to beat too quickly and potentially leading to symptoms like palpitations, dizziness, or shortness of breath.
