February is HEART MONTH


Did you know that RVH offers Cardiopulmonary Diagnostics?

These are services available right here, close to home for your Heart Health!

Cardiac Stress Testing

A treadmill test for the investigation of chest pain, dyspnea and palpitations, which  assists in the detection of ischemia for diagnostic and management purposes and assists in diagnosing abnormal exercise capacity, heart rate, blood pressure.

Cardiopulmonary Stress Testing

A treadmill exercise test with a mouthpiece for the measurement of oxygen uptake and carbon dioxide production.

Cardiopulmonary stress testing is a useful tool in the assessment of patients with cardiovascular and pulmonary disease. Oxygen uptake, carbon dioxide production, minute ventilation, and anaerobic threshold are measured. “VO¬≤ max” is the standard index of aerobic capacity and cardiopulmonary function.

Indications for Cardiopulmonary Stress Testing

  • to assess exertional dyspnea to differentiate cardiac from pulmonary disease
  • to provide post MI risk stratification
  • to provide follow-up post CABG/PTCA for exercise prescription
  • to provide fitness appraisal with VO2 max (maximal oxygen consumption)
  • to determine the cause of exercise impairment
  • to determine exercise capacity
  • to identify abnormal responses to exercise
  • to evaluate impairment/disability
  • to assist with selection of patients for cardiac transplant
  • to assist with pre-op risk stratification


An ultrasound Doppler examination of the heart.

Useful in the diagnosis of:

  • dyspnea
  • heart murmur
  • source of emboli
  • pericardial effusion

Useful in the assessment of:

  • systolic and diastolic function of the right and left ventricles
  • valve function
  • LV size in hypertension

Echocardiography is myocardial infarction will evaluate:

  • wall motion
  • clots
  • ejection fraction
  • effusions
  • ruptures

Body Plethysmography

This state-of-the-art pulmonary function test consists of four components:

  • Spirometry which assists with making differential diagnoses, and monitoring the course of a disease or response to therapy
  • Airways Resistance which helps to differentiate central from peripheral airways disease. It is very sensitive to obstruction in central airways.
  • Diffusion which helps to differentiate asthma from underlying emphysema, and intrinsic lung disease from an extra-pulmonary process.
  • Lung Volumes which help to establish or confirm a diagnosis of restrictive/obstructive lung disease.
