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.

An echocardiogram is a non-invasive ultrasound of the heart that uses sound waves to produce detailed images of heart structure and function.

It is used to evaluate:

  • Heart chambers and valves
  • Pumping function of the heart
  • Blood flow through the heart
  • Heart muscle strength
  • Structural abnormalities

A 72-hour Holter monitor is a portable device that continuously records the electrical activity of your heart over three days while you carry out normal daily activities.

It is used to detect:

  • Intermittent arrhythmias
  • Irregular heart rhythms
  • Palpitations
  • Unexplained dizziness or fainting
  • Medication effectiveness

A 14-day Holter monitor provides extended heart rhythm monitoring over two weeks, increasing the likelihood of capturing infrequent cardiac events.

It is used for:

  • Rare or intermittent arrhythmias
  • Ongoing palpitations
  • Unexplained syncope (fainting)
  • Long-term rhythm assessment
  • Post-treatment monitoring

Our cardiology consultations provide expert assessment and evaluation of cardiac symptoms and test results.

  • Review of cardiac symptoms and history
  • Interpretation of diagnostic tests
  • Risk assessment for heart disease
  • Treatment recommendations
  • Referral for further cardiac testing if needed

An EKG is a quick, non-invasive test that records the electrical activity of the heart.

It is commonly used to detect:

  • Irregular heart rhythms

Our cardiology testing includes non-invasive exams such as ECG (electrocardiogram), echocardiogram, and Holter monitoring, each of which helps physicians assess a different aspect of heart rhythm, structure, and function without surgery or sedation. An ECG records the heart’s electrical activity in just a few minutes, an echocardiogram uses ultrasound to visualize the heart’s chambers and valves, and a Holter monitor is worn for an extended period, typically 24 to 48 hours, to capture heart rhythm during normal daily activity.

Cardiovascular disease remains a leading cause of illness in Canada; general information on risk factors and prevention is available from Public Health Ontario, and details on OHIP coverage for cardiac diagnostic testing are available on the Government of Ontario’s website.
