EKG Reports: Insights for Patients with APL and Dyspnea - Cardiology

Report Interpretation


Hello Dr.
Wu,
Earlier this year, I experienced shortness of breath and underwent an electrocardiogram (EKG) test.
Subsequently, I was diagnosed with acute promyelocytic leukemia (APL) and have been receiving treatment.
I have two EKG reports that I couldn't discuss with a cardiologist, so I would like to ask for your insights.
1.
Other forms of dyspnea
EKG Diagnosis:
■ Normal Tracing
2.
Acute myeloblastic leukemia, not having achieved remission
EKG Diagnosis:
■ Counterclockwise Heart Rotation
■ Flat T waves
What do these findings mean? The first report is from a cardiologist, and since I couldn't return for a follow-up, I'm unsure if everything is normal.
The term "Normal tracing" is unclear to me.
The second report is a follow-up during my treatment, and the cardiovascular oncologist did not provide much information.
I feel fine, but the results seem somewhat concerning, so I wanted to seek your advice.
Thank you.

Fred, 50~59 year old female. Ask Date: 2024/03/09

Dr. Wu Xueming reply Cardiology


The electrocardiogram report does not show any significant abnormalities.

Understanding EKG reports can be quite challenging, especially for patients dealing with complex conditions such as Acute Promyelocytic Leukemia (APL) and associated symptoms like dyspnea (shortness of breath). Let’s break down the findings from your two EKG reports and what they might mean for your health.


First EKG Report: Normal Tracing
The first report indicates a "Normal Tracing." This generally means that the electrical activity of your heart is functioning within normal parameters. A normal EKG shows a regular rhythm, appropriate heart rate, and no signs of ischemia (lack of blood flow) or other abnormalities. For someone experiencing dyspnea, a normal EKG is reassuring as it suggests that the heart is not the primary cause of your symptoms. Dyspnea can arise from various factors, including lung issues, anemia, or even anxiety, especially in the context of a serious illness like leukemia.


Second EKG Report: Counterclockwise Heart Rotation and Flat T Waves
The second report, however, presents some findings that warrant further discussion. The terms "Counterclockwise Heart Rotation" and "Flat T Waves" can indicate specific changes in heart function that may be related to your underlying condition or treatment.

1. Counterclockwise Heart Rotation: This term refers to the orientation of the heart's electrical activity. In a normal heart, the electrical impulses travel in a specific direction. A counterclockwise rotation can suggest that there may be some alterations in the heart's electrical conduction system. This could be due to various factors, including electrolyte imbalances, changes in heart size or shape, or effects from medications you may be taking for leukemia.

2. Flat T Waves: T waves represent the repolarization of the ventricles (the heart's lower chambers) after contraction. Flat or inverted T waves can indicate several issues, such as ischemia, electrolyte imbalances (like low potassium), or other cardiac conditions. In the context of leukemia, it may also reflect the effects of chemotherapy or other treatments that can impact heart function.


Implications for Your Health
Given that you have been diagnosed with APL and are undergoing treatment, it is essential to consider how your condition and its treatment may affect your cardiovascular health. Chemotherapy can have various side effects, including potential impacts on heart function. It is not uncommon for patients with hematological malignancies to experience cardiovascular issues, which can contribute to symptoms like dyspnea.


Recommendations
1. Follow-Up with Your Cardiologist: It is crucial to discuss these findings with a cardiologist, especially since you have a history of dyspnea and are undergoing treatment for leukemia. They can provide a more comprehensive evaluation and determine if further testing, such as an echocardiogram or additional EKG monitoring, is necessary.

2. Monitor Symptoms: Keep a close eye on your symptoms. If you experience increased shortness of breath, chest pain, or palpitations, seek medical attention promptly.

3. Consider Holistic Care: Managing APL and its treatment can be overwhelming. Ensure you have a support system in place, including healthcare providers who can address both your oncological and cardiovascular health.

4. Lifestyle Modifications: Depending on your overall health and treatment plan, consider lifestyle changes that can support heart health, such as a balanced diet, regular physical activity (as tolerated), and stress management techniques.

In summary, while your first EKG report is reassuring, the findings in the second report should be taken seriously. Engaging in a dialogue with your healthcare team will help clarify these findings and ensure that you receive the appropriate care for both your leukemia and any cardiovascular concerns.

Abnormalities in the electrocardiogram (ECG) must be interpreted by a physician in conjunction with clinical symptoms to determine whether the abnormalities have clinical significance. It is recommended that you visit a cardiology outpatient clinic for evaluation.
