Clinical Classification Guidelines
Inclusion Terms
- Premature beats NOS
Medical Intelligence & Overview
Unspecified premature depolarization is a type of cardiac rhythm disturbance characterized by early electrical impulses originating in the heart. These impulses cause premature contractions of the heart muscles, which can be felt as palpitation or skipped beats. This condition, classified under ICD-10 code I49.40, typically indicates an irregular heart rhythm that doesn't fit into more specific categories, hence the designation 'unspecified.' While often benign, frequent or persistent premature depolarizations can signal underlying heart issues requiring medical attention.
Causes & Symptoms
