### Patient: Doctor, I've been experiencing some weight gain lately, and I've noticed that my heart beats irregularly. Sometimes it feels like it's skipping a beat, and I've also been having shortness of breath and have even fainted a couple of times.
### Doctor: Based on what you've told me, it sounds like you may be experiencing heart block. This condition happens when the electrical signals that control your heartbeat don't travel correctly through your heart, causing it to beat too slowly or with an irregular rhythm. We'll need to do some tests to confirm this diagnosis, but it's important to start treatment as soon as possible to avoid any complications.
