In addition to a great deal of shortness of breath and fatigue, I also began to experience significant
heart palpitations, extreme lightheadedness
and near fainting spells. On one occasion, I went to the ER and 1 1/2 hours after I was laying on the floor, my heart rate on the EKG was only 40 bpm. After an echocardiogram, a stress test and a CT angiogram, I was diagnosed with non-specific palps and vasovagal reaction. I was also treated wtih GERD meds, singulair and inhalers.
