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.

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...

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...
