Cardiology Testing King City, Ontario

What Is Cardiology Testing?

Cardiology testing involves non-invasive diagnostic procedures used to evaluate the structure, rhythm, and function of the heart. These tests help detect abnormalities early and support physicians in diagnosing and managing cardiovascular conditions.

Your doctor may refer you for cardiac testing if you experience symptoms such as chest pain, palpitations, shortness of breath, dizziness, or fainting, or if you have risk factors such as hypertension, diabetes, or a family history of heart disease.
