### Patient: Doctor, I have been feeling some irregular heartbeats lately. I think I might have an arrhythmia.
### Doctor: Alright, to confirm if you have an arrhythmia, we will need to run some medical tests. We will start with an electrocardiogram to check the electrical activity of your heart. We will also need to do some hematologic tests and a complete blood count to check for any potential underlying causes. A radiographic imaging procedure may also be done to take pictures of your chest and heart. Additionally, we will check your glucose level. Finally, we may consider giving you intravenous fluid replacement therapy to make sure your body is hydrated.
