Can anyone tell me something about ectopic atrial tachycardia? I had an ablation for avnrt, but still have breakthrough episodes and doc says this.

Ablation. you might be having recurrence of avnrt, another type of arrhythmia but first the episodes should be documented with tests like Holter, event recorder before jumping into conclusions.
Atrial Tachy. Ectopic atrial tachycardia is cause by an abnormal focus in the atrium causing the heart rate to increased. This can certainly be ablated but complexity depends on the location - right vs. Left atrium. Medication may also be tried. Best of luck.
Different focus. Assuming your av nodal re-entrant tract was well and fully ablated, and you're now having a different tachycardia, your cardiologist is suggesting that there is an abnormal spot in the atrium initiating rapid abnormal beats. May need different drugs or another procedure.

Does reentry tachycardia and ectopic atrial tachycardia look the same way? I was connected to telepathy for 5 days in hospital and doc said I had EAT

Yes. Depending on the rate, a reentry tachycardia usually has no visible p waves on telemetry or EKG whereas an ectopic atrial tachycardia often will have a visible p wave, but not always. They can be hard to distinguish on external (non intracardiac) tracings. Read more...

The doctor said that they "think" I have ectopic atrial tachycardia. Can it actually have been interpretated wrong on the ECG or should I trust them?

ECG=not best. The ECG only provides clues to the mechanism of an atrial tachycardia. The exact mechanism can only be determined with intra-cardiac electrodes. Nonetheless, I would stick with your doctors - there are many treatment options, but they the must be tried empirically. If the problem is refractory, an electrophysiologic study can always be done down the road. 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...

Dysautonomia - MVP . You may have dysautonomia which is associated with mitral valve prolapse syndrome - neither are usually life threatening but both cause patients anxiety about their symptoms. Read dr. Richard hoffman's book on mvp on amazon.Com. Increase fluid and salt intake, try magnesium supplements. Ultra low dose beta blockers can be initiated and then up-titrated to control symptoms . Read more...
