Pulmonary Atrial Tachycardia
Common: It's surprisingly common and can occur in normal hearts in the absence of heart disease. It can be caused by cardiac stimulants like caffeine, nicotine, amphetamine, alcohol, and certain medicines like bronchodilators, atropine, and adrenalin. Thyroid excess can cause it. Stress and lack of sleep can contribute. It occurs for no recognized reason in some. ...Read more
Atrial tachycardia is a symptom in which a person's heart rate is faster than normal for his age or for the activity he is doing, and the electrical impulse for his heartbeats starts in the upper part of the heart (the atria). An electrocardiogram (EKG or ECG) ...Read more
Tachycardia: Multifocal atrial tachycardia is a form of SVT. ECG and Holters should help. Sometimes you need electrophysiology study. ...Read more
SVT and MAT: Mat is a kind of svt. Usually mat implies significant cardiac or pulmonary pathology. Svt can happen in less abnormal hearts. ...Read more
What to do if I have atrial tachycardia and was wondering if I would be able to get a cool adventurous job?
Why not: Atrial tachycardia is common in people. When we get excited, frightened, run or do something strenuous. In most cases it will not interfere with our job related activities if it is mild. If you have another kind of tachycardia, then you need to give us a more definite diagnosis. ...Read more
Many tests ordered by cardiologist.He found "atrial tachycardia" on 48 hr holter during symptoms.All other tests good. What does this really mean?
Abn heart rhythm: Paroxysmal atrial tachycardia is an abnormal heart rhythm propagated by a variety of mechanisms. The HR typically is 170-240 but exceptions occur. It usually causes palpitations and, if prolonged, may cause shortness of breath and/or dizziness. The albuterol you take can precipitate it. It can occur in otherwise normal hearts. Meds or ablation can prevent it. ...Read more
If u have ectopic atrial tachycardia, does the ectopic signal cause the ventricles to beat too? And what's the difference with reentry tachycardia?
EAT: Atrial tachycardia, regardless of mechanism, conducts to the ventricles. The main issue with any form of atrial tachycardia is that the rapid ventricular rate can result in annoying symptoms and, if fast and persistent, can eventually weaken the heart. The difference between EAT and reentry is one of mechanism. (ie how the electrical impulse is conducted). Incessant EAT requires treatment. ...Read more
Automatic atrial tachycardia with exercise? How do you differentiate from innapropriate sinus tachycardia? Which would be more likely in an athlete?
Tachycardia: Inappropriate sinus tachycardia - elevated heart rate (HR) at rest > 100 sitting/standing. Athletes usually have a slow HR at rest. Atrial tachycardia/fibrillation/flutter with excessive HR more common in extreme athletes with exercise. Cause unclear - may be due to electrical changes from extreme endurance exercise to atrial electrical properties of the heart. More exercise not always better. ...Read more
Monitored for 5 days and they saw something they "thought" was ectopic atrial tachycardia.Could it have been something else like reentry tachycardia?
Yes: Ectopic atrial tachycardia is unusual and hard to pin down from a monitor. It was more likely re-entry. ...Read more
Sinoatrial node.: The normal heart rate "pacemaker" center is in the sinoatrial node, a part of the right atrium. Ectopic atrial tachycardia means that the pacemaker region (the part that is setting the heart rate) is in another location, & is acting erratically. Atrial tachycardia implies that it is the sinoatrial node that is acting erratically. They are similar, but the heartbeat starts at different points. ...Read more
EP procedure: This is generally done in a cath lab using wires similar or pacemaker electrodes. They are inserted through blood vessels in the leg, and place into the heart. There they "read" electrical activity to determine where the abnormal conduction is taking place. Then the offending circuit can be severed using radio-frequency ablation. ...Read more
Pacemaker: One solution for hard to treat atrial tachycardia may involve the use of a pacemaker; however, this is usually reserved for older people who can not tolerate other treatments, or they are ineffective. Medications can be tried. Catheter ablation is often a successful cure. Request a cardiac electrophysiology referral, to discuss options. ...Read more
Great question: It's variable depending on location (left vs right sided). Talk to the electrophysiologist who would perform to get best information specific. ...Read more
Neither: Neither is worse, both require treatment when they cause symptoms. ...Read more
No definite rules...: Can differentiate these 2 arrhythmia types, although ventricular tachycardia generally causes more severe symptoms such as chest pain, fainting and even a cardiac arrest. Atrial tachycardia almost never causes cardiac arrest, although can be felt as palpitations with lightheadedness or difficulty breathing. ...Read more
Ablation: Ablation therapy is done to destroy tissue in the heart that is causing electrical or mechanical problems. Usually the technique used is radiofrequency energy like microwaves but there are also other techniques. Most commonly these are performed by electrophysiology specialists. ...Read more
My ectopic atrial tachycardia first showed when becoming really stressed. How is this related? Do I have dysautonomia?
Results of a 24-hour holter test: 9 VPC's, 381 APC's, 3 nonsustained atrial tachycardia 4-9 beats each, at 100-102 beats/min. Is this normal?
like a bit too many APC''s The reason for this , in my opinion, should be determined..(EG Cardiac ECHO) Hope this helps!
BTW nothing "dangerous" but needs attention!

I have a pacemaker for bradycardia but over the past two months my pacemaker has been reading a high rate of atrial tachycardia should I be worried?
Monitor: To know what your pacemaker is recording, you must be seeing your doctor to have the device interrogated. You should ask your doctor the meaning of the rhythms that the device is recording and whether anything else is needed. ...Read more
Can atrial tachycardia start all of a sudden or have i had it all my life or can someone just develop a fast heart rate i'm f 30 no history of heart?
It can start suddenl: It is unlikely that you had it all your life without a doctor noticing it and without you knowing it. ...Read more
Have ectopic atrial tachycardia.Is it someting u are born with or can it develope over time?if the latter what can cause it?came after extreme stress
Happens: If it is truly ectopic atrial tachycardia as opposed to reentry tachycardia, it IS something that just happens over time and is usually due to extreme stress and/or cardiac stimulants such as nicotine/caffeine/asthma meds/amphetamines. A betablocker often will help. Reentry tachy requires that you're born with the predisposition, & can be treated with meds or ablation. ...Read more
What do you advise if I'm currently on medication for paroxsymal atrial tachycardia but have been experiencing fluttering and pain in chest for 3 days?
Adjust meds: You need to contact your cardiologist or electrophysiologist as your medications may need to be adjusted ...Read more
Yes.: Faster heart rates can lead to reduced blood supply to your heart, therefore pain... You need to investigate the causes with the help of a physician... Best luck and happy easter sunday! ...Read more
