What to Expect During a Heart Stress Test: Preparation, Procedure & Recovery

A heart stress test assesses how well your heart performs during physical exertion. It is commonly used to investigate chest pain, shortness of breath, or possible coronary artery disease. Understanding what to expect during a stress test can help you feel more confident and prepared.

Before the test, you may be advised to avoid caffeine, heavy meals, or certain medications. Wear comfortable clothing and supportive shoes, as the test usually involves walking on a treadmill or cycling on a stationary bike.

During the procedure, ECG electrodes are placed on your chest to monitor your heart rhythm. Your blood pressure and heart rate are also checked regularly. The exercise intensity increases gradually, allowing clinicians to see how your heart responds as demand rises. You will be closely supervised at all times.

Most stress tests last 20–40 minutes, including preparation and recovery time. The exercise portion itself is usually shorter, often around 10–15 minutes. You can stop at any time if you feel unwell, excessively tired, or develop symptoms.

After the exercise phase, you’ll be monitored while your heart rate and blood pressure return to normal. Many people feel slightly tired but recover quickly and can resume normal activities later the same day.

Stress tests are safe and widely used, providing valuable information about blood flow to the heart and exercise tolerance. They help cardiologists decide whether further investigations or treatments are needed.
