Hi, Thanks for writing back.
1. "Pulmonary edema is often caused by congestive heart failure. When the heart is not able to pump efficiently, blood can back up into the veins that take blood through the lungs." If Edema occurs, the natural functions of the lung are impaired. Myself, since I was diagnosed with Chronic Urticaria (Hives) I was put on Singulair. As a result, my breathing has been much more normal now, and the rate of contracting colds seems to be at an adult (for me) all time low. Prior to taking Singulair, I was using a Steroid Inhaler, it just didn't work as well as Singulair does for me. If your lungs are compromised, it may be contributing to infections that are the prelude to pneumonia.
2. You may be regarded as Pacemaker Dependent, but ask your doctor for more specifics. The heart beat originates in the SA Node on the top of the heart, travels a pathway to the AV Node between the top and bottom of your heart, and then down to the bottom. Some patients with a Pacemaker have AV Node Ablation, preventing the erratic signals from your AFib from reaching the bottom of your heart. I'm no doctor, but I've read that once the patient is provided with a Pacemaker, and at some point the AV Node is ablated, that Atrial Fibrillation ceases to be a problem for your heart rate, it can't reach the Ventricles.
Is your fast heart rate due to Afib? What are they trying to ablate? The Pulmonary Veins that return oxygenated blood to the Left Atrium are a common source of Afib, there's 4 veins, and they have the unique distinction of being the only veins (vs Arteries) that carry Oxygenated Blood.
Look forward to hearing more.
GoodMorning @soliloquized am just now seeing your response (so sorry). The responses were going to my spam email and I was deleting the spam not knowing. Now that made me sad because I didnt get to read all the responses from my original post. My fast heartrate is due to Afib. They ablated back in Jun 2018 but it was unsuccessful. My heartrate jumps to 130 to 160 bpm so they have been upping my rythmol which is crazy it has my body feeling outright exhaused. I recently was told am having PAC in the upper chamber which is what may be causing my palpitations. Its a horrific feeling all off in my neck and only so at night. I think EP and cardiologist is thinking of ablating again but my body is so tired. They are trying to look into other options i was told by the nurse. Am not sure now what they are trying to ablate but I now will certainly ask. I am having these palpitations and night sweats often. Am so scared the heart will get tired and stop. Am just not sure what else to do or ask. Thank you so much for your response. Hope you are doing well...
