When your heart starts beating fast or if it “feels funny,” or really just about anything related to the heart can be scary.
Here’s the short answer: Afib stands for atrial fibrillation, which is basically an irregular heartbeat, or arrhythmia. On the other hand, supraventricular tachycardia (SVT) stands for rapid heartrate.
Despite what you might think, they’re very different. For instance, a heart can beat quickly but not irregularly. Likewise, a heart can beat irregularly but not quickly.
According the American Heart Association, a heart rate of more than 100 beats per minute (BPM) in adults is called tachycardia. What’s too fast for you may depend on your age and physical condition.
A single panic attack can last a few minutes or an hour. A type of arrhythmia called supraventricular tachycardia (SVT) can make your heart beat as much as 150 to 250 times a minute. This is the heart arrhythmia most likely to be mistaken for a panic attack. An episode of SVT can last 5 seconds or until your doctor does something to stop it.
