Queen-what you describe is the way my Lyme literate Cardiologist explained it.
I wore a monitor for 24 hours and had an echocardiogram. I just saw the Cardiologist this afternoon for the results. At my earlier appt he had told me that I had irregularities but he believed those were from the disease and not from damage to my heart.
The echo showed that my heart is in excellent shape. The monitor showed that I have PACs and PVCs.
I'm cutting and pasting the info below from here if anyone wants to read it more thoroughly.
www.medicinenet.com/heart_rhythm_disorders/page3.htm"Many people may have heart rhythm disturbances and never be aware of them. Premature atrial contractions (PACs) and premature ventricular contractions (PVCs) are variations of normal and most often, people are unaware that an extra beat has occurred. However, some patients are keenly aware of any extra heartbeat, even if it is a normal variant and requires no treatment.
That said, the initial symptom of dysrhythmia is often palpitations, a sensation that the heart is beating too quickly, too slowly, beating irregularly, or skipping a beat. The palpitations may be intermittent or may require medical intervention to resolve.
Because of the heart rhythm abnormality, other symptoms may occur because of decreased cardiac output (the amount of blood that the heart pushes out to meet the body's demand for oxygen and energy). The patient may complain of lightheadedness, weakness, nausea and vomiting, chest pain, and shortness of breath."
My doctor said that mine are coming from the same spots every time so he believes that's where the disease has decided to get comfortable. Continued treatment will make these dissipate and exercise is not a concern.
