My mother has atrial fibrillation. There are heart problems on my dads side. And I ve developed an arrhythmia with occasional syncope, Loss of breath, vertigo and occasional weakness and exhaustion. It interfere witg my work so im on leave. My dr sent me for blood work to check my iron and thyroid. I had an ecg and an echo as well as 2 -24hr holter monitor all that were done when palpitations weren t present. They come and go but mostly they are a daily struggle. My dr since then has prescribed mr 10mg of cipralex and .25 mg of xanax sayin that im depressed and suffer from anxiety. Im not depressed in the least. Im actually happier than II have been before and don t suffer from racing heart only during exertion. Now I have seen the health care warning with cipralex and im hesitant to go on it ...
