After some test results that were good, I am left wondering why am I having these heartbeats that are so random and out of synch. What I want to know is, can they be caused only by having anxiety (I can understand that panic attacks cause them, but just anxiety, although admittedly because of the beats my anxiety is very high)? Also, once you have them can they ever go away? Is it possible for your heart to retrain itself to ignore whatever is causing the rythm to go awry?

I am hoping and hoping someone is going to tell me they aren't a lifelong condition.

Okay, this has been discussed many times. Just because you experience symptoms does not mean that something is wrong. You have to acknowledge this fact in order to begin moving beyond your anxiety where this is concerned. Let me give you an example for illustration; If you place your arm in the proper extended position, it is quite common for the radian and medial nerves to become slightly compressed and cause parasthesia along the forearm, hand and outer digits. This does not mean that you have a damaged nerve or that disease is responsible for the symptoms. The very same circumstances hold true for Vagus nerve stimulation and associated anxiety. The Vagus nerve is responding inappropriately due to stimulation, but it does not mean that the symptoms produced are caused by "disease" of any kind.

Patients become very frustrated by this because when their heart acts abnormally from what they normally expect and exprerience, it can become very frightening and the first conclusion drawn is that it represents something wrong. It is just not the case here, nor will it ever be the case under these circumstances. Negative tests are negative, negative, negative and will not change just because benign symptoms are present. Patients are simply accustom to making direct relationships between symptoms and illness. It does not apply here. You have a condition and not an illness or disease of any type. It will never cause your heart to become damaged, nor will it ever cause you to experience a cardiac event of any type. Knowing this, you must logically begin to accept this and look for ways to improve your knowledge on the topic, which will improve your rationale about the events and diminish anxiety.  

You're going to be fine. Time spent educating yourself about the symptoms and their cause will go a long way to reduce anxiety and boost your outlook on things.

And finally, many if not most patients experience a reduction in symptoms when anxiety is reduced or abated through professional counseling and treatment where necessary. Spontaneous resolution is also very common.

Best regards and Good Health
