Heart Rhythm Problems: Diary of Symptoms-Topic Overview If your doctor thinks you might have a heart rhythm problem, he or she may ask you to keep a diary of symptoms. This information can help your doctor find out what type of rhythm problem you have.

And if you have a rhythm problem, a symptom diary can help you keep track of your condition. You can then discuss your symptoms with your doctor at your next appointment.

In your diary, include the following:

• How fast or slow was your heart beating? Be aware that if your heart is beating very fast, you may not be able to accurately determine your heart rate.
• Was your heart rhythm regular or irregular?
• What symptoms did you have?
• What time of day did your symptoms occur?
• How long did your symptoms last?
• What were you doing when your symptoms started (such as drinking alcohol or smoking)?
• What may have helped your symptoms go away?
