Exercise ECG Reports: Insights into Cardiac Health - Cardiology

More Info

---

Understanding exercise ECG reports is crucial for assessing cardiac health, particularly in individuals experiencing symptoms such as chest pain. Your report indicates several key findings that warrant careful interpretation.


Overview of the Report
1. Resting ECG: The report notes a sinus rhythm with non-specific ST-T changes. This suggests that while the heart is functioning normally at rest, there are some minor abnormalities in the electrical activity of the heart that could be indicative of underlying issues.

2. Exercise Test Summary:
- Protocol: The Bruce protocol is a standard treadmill exercise test used to evaluate cardiovascular fitness and the heart's response to stress.

- Max Heart Rate: Achieving a peak heart rate of 162 bpm, which is above the predicted maximum heart rate (MHR) indicates a good effort during the test.

- Exercise Duration: The total exercise time of 6 minutes and 23 seconds with a METS achievement of 8.2 suggests a moderate to high level of exercise capacity.

3. Blood Pressure Response:
- Resting blood pressure was recorded at 145/87 mmHg, which is slightly elevated.
- The peak systolic blood pressure reached 182 mmHg during exercise, indicating a normal physiological response to exercise, as blood pressure typically rises with increased physical activity.

4. Termination Reasons: The test was terminated because an adequate heart rate was achieved, which is a standard practice to ensure the patient is not overexerted.

5. ECG Changes During Exercise: The report highlights a significant finding of ST-T horizontal depression greater than 1 mm in leads II, III, aVF, V4, V5, and V6. This is particularly concerning as it may indicate myocardial ischemia, which is a condition where the heart muscle does not receive enough blood and oxygen during exertion.


Interpretation and Recommendations
The presence of ST segment depression during exercise is a potential indicator of coronary artery disease (CAD) or other cardiac issues. Given your symptoms of chest pain, this finding should not be taken lightly. Here are some considerations:
1. Further Evaluation: Given the ST-T changes observed during the exercise test, it is advisable to pursue further diagnostic testing. This could include:
- Coronary Angiography: This is an invasive procedure that allows for direct visualization of the coronary arteries to assess for blockages.

- Myocardial Perfusion Imaging: A non-invasive test that can provide information about blood flow to the heart muscle during rest and stress.

2. Symptom Management: Since you are experiencing chest pain, it is crucial to monitor these symptoms closely. If they persist or worsen, immediate medical attention is warranted.

3. Lifestyle Modifications: In conjunction with any medical treatment, lifestyle changes such as a heart-healthy diet, regular exercise (as tolerated), and smoking cessation (if applicable) can significantly improve cardiac health.

4. Medication Review: If you are already on medications for blood pressure or cholesterol, ensure that these are reviewed and adjusted as necessary by your healthcare provider.

5. Follow-Up: Regular follow-up appointments with your cardiologist are essential to monitor your condition and adjust treatment plans as needed.


Conclusion
In summary, while your exercise ECG report shows some positive aspects, the ST-T changes during exercise raise concerns that should be addressed promptly. It is essential to work closely with your healthcare provider to determine the best course of action for further evaluation and management of your cardiac health. Your symptoms of chest pain should not be overlooked, and proactive measures are necessary to ensure your safety and well-being.
