I have been seeing a Cardiologist due to an abnormal stress test. The test showed atrial flutter with 2:1 heart block. I am almost 37, and I have had abnormal EKGs since at least about 1999/2000 that I know of because of bradycardia. My heart rate is usually in the high 40s to low 50s. I am not an athlete :). I had an echo that was normal with 60-65% EF and only trace tricuspid and pulmonic valvular regurgitation. The Cardiologist did a nuclear stress test that showed EF at 60% but abnormal EKG with NSR, anteroseptal MI. There was a "moderate sized basal and mid segment anterior wall perfusion abnormality of moderate intensity that worsens during stress, suggestive of reversible ischemia. Appeared to be old MI with mild peri-infarct ischemia". I also did a Holter which showed some supraventricular beats, but not much else. I had a left heart cath with EF 65% and only a mild increase in end-diastolic pressures. My arteries were not blocked. Meanwhile, for at least the last couple of years, my ankles and legs have been severely swollen and now will no longer respond to diuretics. I responded much better to fluid restriction, but I am still swollen. I have bouts daily with palpitations, chest pain, difficulty breathing when lying flat and sometimes while just sitting, and a weird dizziness that makes me feel as though I am going to pass out (I have never actually passed out). I have gained about 20 lbs in just a few months, mostly because of water retention. Other than nitroglycerin, I am not on meds. I was taking Diltiazem, but my cardiologist took me off after the heart cath, stating that nothing is wrong with my heart and it's just my Gerd. Because of the palpitations, chest pain, edema, and difficulty breathing while lying flat, I think I want to get a second opinion just in case. My maternal grandmother had CHF, so I am always a little concerned about my heart. My EF is good, but I know that a good EF doesn't always mean you're in the clear. My cholesterol is at 216, so I am making diet changes right now. My blood pressure is usually very good (example 116/78), but I do have occasional rises. Has anyone ever dealt with anything similar with a good EF? What was the issue? This whole thing is starting to baffle me, because everything seems to be good except the stress tests and how my body feels.
