Your Exercise ECG Report: Key Insights for Patients - Internal Medicine

Understanding your exercise ECG report is crucial for assessing your cardiovascular health and determining any potential risks. Based on the details provided in your report, let's break down the key components and their implications.


Key Components of Your Exercise ECG Report
1. Target Heart Rate (THR): Your target heart rate was set at 181 beats per minute (BPM), and you achieved a maximal heart rate of 176 BPM, which is 97% of your THR. This indicates that you were able to reach a high level of exertion during the test, which is generally a positive sign of cardiovascular fitness.

2. Resting ECG: The report indicates that your resting ECG showed normal sinus rhythm (NSR). This is a good sign as it suggests that your heart is functioning normally at rest.

3. Termination of Exercise: The test was terminated due to shortness of breath (SOB) after completing stage 4 of the Bruce protocol, lasting 10 minutes and achieving a workload of 11.8 METs. This level of exertion is commendable and indicates a good level of fitness, although the onset of SOB is something to monitor.

4. Blood Pressure Response: Your maximal blood pressure during the test was recorded at 232/69 mm Hg. While the systolic pressure (232 mm Hg) is elevated, it is not uncommon for blood pressure to rise significantly during intense exercise. However, it is essential to discuss this with your healthcare provider, as sustained high blood pressure during exertion could indicate underlying issues.

5. Exercising ECG Findings: The report notes sinus tachycardia with premature atrial contractions (PACs) and non-specific ST-T changes. Sinus tachycardia is a common response to exercise, indicating that your heart is working harder to supply oxygen to your muscles. PACs are generally benign but can be a sign of increased atrial irritability. Non-specific ST-T changes can occur in response to various factors, including exercise, but they warrant further evaluation to rule out any underlying ischemic changes.

6. Conclusions: The overall conclusion of the exercise ECG is negative, suggesting that there were no significant ischemic changes during the test. This is a reassuring finding, indicating that your heart is likely functioning well under stress.


Implications and Recommendations
While your exercise ECG report shows several positive indicators, there are a few areas that warrant further discussion:
- Shortness of Breath: The occurrence of SOB during the test should be evaluated further. It may be beneficial to discuss this symptom with your healthcare provider, especially if it occurs frequently during physical activity.

- Elevated Blood Pressure: The high systolic blood pressure recorded during exercise could be a point of concern. It is advisable to monitor your blood pressure regularly and discuss any necessary lifestyle modifications or medications with your physician.

- PACs and ST-T Changes: While PACs are often benign, they can sometimes indicate an increased risk for other arrhythmias. The non-specific ST-T changes should also be monitored, and if you experience any symptoms such as chest pain or significant fatigue, further testing may be warranted.


Conclusion
In summary, your exercise ECG report indicates that your heart is functioning well under stress, with no significant ischemic changes detected. However, the presence of shortness of breath, elevated blood pressure, and PACs should be discussed with your healthcare provider for a comprehensive evaluation. Regular follow-ups and monitoring will help ensure that any potential issues are addressed promptly, allowing you to maintain your cardiovascular health effectively. Always feel free to ask your doctor any questions or express concerns regarding your heart health and exercise tolerance.
