R001 - Slow heart rate (less than 60 beats per minute) without a specific underlying cause identified

International Classification of Diseases

Last updated: 10/3/2025

What is a ICD-10 Code?

ICD-10 (International Classification of Diseases, 10th Revision) codes are used to classify and code all diagnoses, symptoms, and procedures recorded in association with hospital care. These codes provide a standardized way to track health conditions and their treatment outcomes.

Detailed Description

Bradycardia means your heart is beating slower than normal - typically less than 60 beats per minute when at rest. 'Unspecified' means your doctor has documented that you have a slow heart rate, but hasn't yet determined or specified the exact cause. This could be due to various factors like medications, heart conditions, or sometimes it can be normal for very athletic people. Your doctor will likely want to investigate further to understand why your heart rate is slow and determine if any treatment is needed.

Additional Information

Bradycardia can be normal in athletes or may indicate an underlying condition requiring treatment. Symptoms may include fatigue, dizziness, or fainting, but some people have no symptoms at all.
