Questions about electrocardiogram (ECG) reports?
Hello Doctor: Last July, I underwent a health check-up, and the results of my resting electrocardiogram showed low voltage.
After exercise, the ECG results indicated ST elevation.
However, I had a cardiac ultrasound at another hospital that showed normal results.
This year, I have been experiencing discomfort in my heart (above the stomach) and headaches.
I would like to ask what conditions these symptoms might indicate and how I can improve them.
Can exercise help? Is there a relation to obesity as well? Thank you, Doctor.

Dr. Bu Shiyun reply Cardiology
If someone is particularly obese, the electrocardiogram (ECG) may indeed show low voltage due to the body being less conductive.
However, this is just one of the possible reasons and not necessarily the only one.
An elevation in the ST segment after exercise in asymptomatic young individuals may simply be a normal response to physical activity.
Discomfort in the upper abdomen is mostly related to gastric factors; typically, stomach pain reflects our stress levels.
Increased anxiety can also lead to headaches, which may indicate that you are experiencing higher stress or fatigue recently.
Exercise can help us relax and improve our well-being.
It might also be beneficial to talk to friends or mentors about the issues causing your anxiety to help shift your mood!

More Info
Understanding ECG reports and their implications for heart health can be quite complex, especially when symptoms are involved. Based on your description, it seems you have experienced a series of tests, including an ECG and an echocardiogram, with varying results. Let’s break down your situation and address your concerns regarding heart health, symptoms, and potential solutions.
ECG Reports and Symptoms
1. Low Voltage on Resting ECG: A low voltage ECG can sometimes indicate conditions such as obesity, chronic obstructive pulmonary disease (COPD), or pericardial effusion. However, it can also be a normal variant in some individuals.
2. ST Segment Elevation on Exercise ECG: ST segment changes during exercise can indicate myocardial ischemia, especially if they are accompanied by symptoms such as chest pain or dyspnea. However, ST elevation can also occur in athletes or individuals with a high level of fitness, where it may not indicate pathology.
3. Normal Echocardiogram: The echocardiogram showing normal results is reassuring. It suggests that the structural aspects of your heart, such as chamber sizes and wall motion, are functioning well.
Symptoms You Are Experiencing
You mentioned discomfort in the area above your stomach and headaches. These symptoms can be multifactorial and may not necessarily indicate a cardiac issue. However, they could be related to:
- Gastroesophageal Reflux Disease (GERD): Sometimes, heartburn or acid reflux can present as discomfort in the upper abdomen and can be mistaken for heart-related pain.
- Anxiety or Stress: Psychological factors can manifest as physical symptoms, including headaches and chest discomfort.
- Musculoskeletal Issues: Pain in the chest area can also arise from muscle strain or other non-cardiac sources.
Recommendations for Improvement
1. Lifestyle Modifications:
- Diet: A heart-healthy diet rich in fruits, vegetables, whole grains, and lean proteins can help manage weight and improve overall cardiovascular health.
- Exercise: Regular physical activity is crucial. It can help reduce weight, improve heart function, and alleviate symptoms related to anxiety and stress. Aim for at least 150 minutes of moderate aerobic exercise per week, such as brisk walking, swimming, or cycling.
- Weight Management: If you are overweight, losing even a small percentage of your body weight can significantly improve heart health and reduce the risk of cardiovascular diseases.
2. Monitoring Symptoms: Keep a diary of your symptoms, noting when they occur, their intensity, and any associated factors (like food intake or stress levels). This information can be valuable for your healthcare provider.
3. Consultation with a Specialist: Given your symptoms and previous test results, it would be prudent to follow up with a cardiologist. They may recommend further testing, such as a stress test or a Holter monitor, to assess your heart's function during physical activity and over a 24-hour period.
4. Stress Management: Techniques such as mindfulness, yoga, or cognitive-behavioral therapy can help manage anxiety and stress, which may alleviate some of your symptoms.
Conclusion
In summary, while your ECG and echocardiogram results provide some reassurance, your symptoms warrant further investigation. Lifestyle changes, particularly in diet and exercise, can significantly impact your heart health and overall well-being. It is essential to maintain open communication with your healthcare provider to address your concerns and develop a tailored plan for your health. If you experience any worsening symptoms, such as severe chest pain, shortness of breath, or dizziness, seek immediate medical attention.
