Are you seeing a Cardiologist? If not, ask for a referral to one.

A Holter Test might best serve you to find out what is going on.

Good luck.

Arrythmia & palpitations, or ''irregular heartbeat''. It is good that ur heart is solid under stress, so no angina or valve problems.

This is usually a drug reaction, or caffeine, or stress; even panic attack. Cocaine is the worst culprit; next anti-histamines & cold medications. They r not to be taken by people with heart symptoms. You know ur history & the reason for the stress test/treadmill?

Then remove what is causing it, or visit the emergency/doctor, if u see no probable cause.

l suggest you get off the internet and go to a hospital.

Sounds like palpitations which may indicate an arrhythmia. Often a sensation of ''skipped beats'' is due to an arrhythmia called premature atrial contractions which is not anything to worry about. Your doctor could have u wear a holter monitor (like a portable EKG) to determine if you're having a dangerous arrhythmia throughout the day. A good stress test is reassuring that u do not have a serous arrhythmia but for ur peace of mind u may want to talk with ur doctor about it.
