### Patient: Doctor, I have been feeling very dizzy and weak lately. I'm also experiencing shortness of breath and chest pain, especially when I'm physically active. I think I might have a heart problem.
### Doctor: Based on your symptoms, we should conduct some tests to determine the cause of your condition. We need to start with an electrocardiogram to rule out any heart block. We also need to do radiographic imaging procedure, complete blood count, plain x-ray, glucose measurement, and cardiac enzymes measurement. We might also need to provide you with intravenous fluid replacement to see if that helps alleviate your symptoms.
