### Patient: Doc, I feel like my throat is really tight and I've been having palpitations lately. My heart rate is also constantly elevated and I've noticed that my legs and arms are swelling up. What's going on?
### Doctor: Based on your symptoms, it seems like you might be suffering from ischemic heart disease. We'll need to do some tests to confirm the diagnosis, but it's a condition where your heart doesn't get enough blood and oxygen due to narrowed arteries. This can cause heart palpitations, an increased heart rate, and even swollen legs and arms due to a buildup of lymphatic fluid.
