PAT stands for paroxysmal atrial tachycardia. It's a type of paroxysmal supraventricular tachycardia (PSVT) that usually comes from a localized area of heart muscle in the top chambers of the heart called the atria. This means your heart suddenly starts beating very fast. This may feel like your heart is racing or pounding. Because it comes on so quickly, it's often scary. But this is usually not a dangerous condition. PAT can last seconds, minutes, or hours.
PAT can occur in otherwise healthy people who have used too much of a stimulant, such as tobacco or caffeine. Caffeine is found in coffee, tea, cola, and some medicines. Some over-the-counter cold and sinus remedies, diet pills, and some herbal supplements can also overstimulate the heart. The street drugs cocaine and amphetamine are the most powerful heart stimulants. You must not use these.
Overactive thyroid and some types of heart valve disorders can also cause PAT. You may have tests done to find out if this is the cause if your health care provider suspects it.
Home care
Follow these guidelines when caring for yourself at home:
-
Rest today. Go back to your normal activities as soon as you are feeling OK. Sometimes a long episode of PAT can leave you feeling tired and weak for a while.
-
To prevent having PAT come back, stay away from all the stimulants listed above. If you have trouble giving up coffee, switch to decaf. If you smoke, try to stop or at least switch to a filtered, low-nicotine type of cigarette while you look for a stop-smoking program.
-
If you have another episode of PAT, lie down and try to remain calm. These spells usually stop by themselves within a few minutes.
Follow-up care
Follow up with your health care provider within the week, or as advised.
When to get medical advice
Contact your health care provider right away if your palpitations continue longer than normal.
Call 911
This is the fastest and safest way to get to the emergency department. The paramedics can also start treatment on the way to the hospital, if needed.
