I30-I52: Other forms of heart disease
I45: Other conduction disorders
Other conduction disorders are a group of conditions that affect the electrical system of the heart, specifically how electrical signals pass through the heart. This electrical system controls heart rhythm and helps the heart pump blood throughout the body. A conduction disorder can cause an irregular heartbeat, or arrhythmia, which could feel like a racing heart or make it hard for the heart to pump blood correctly. Causes can vary and may include heart disease, abnormal potassium or calcium levels, some medications, or an underlying genetic condition. Symptoms are often related to the irregular heart rhythm and can range from mild or no symptoms to very noticeable ones such as fatigue, dizziness, shortness of breath, chest pain, or even fainting. Other conduction disorders are usually progressive, which means they can get worse over time and can impact a person's quality of life or lead to more serious heart problems.
