ECG is a significant diagnostic tool when it comes to assessing heart health. However, the question comes to our mind whether it can detect blocked arteries. Below, the top doctors of the best echocardiogram centre in Newtown have discussed the role of ECG in detecting blocked arteries.
Detection of blocked arteries
Blocked arteries often occur as a result of Coronary Artery Disease (CAD). It can significantly obstruct the blood flow to the heart muscle. ECGs are valuable when it comes to detecting changes in the electrical patterns of the heart that can further indicate blockages. When the flow of blood is reduced due to a blocked artery, the heart’s electrical signals can shift from their normal patterns, and can be easily identified by an ECG.
How does an ECG detect blocked arteries?
1. ST-Segment changes: One of the key signs of blocked arteries is changes in the ST-segment in the ECG. The ST segment indicates the time between polarization and depolarization of the ventricles. When a blockage occurs, the blood supply to a part of your heart muscle gets compromised, causing changes in the segment. Such changes are commonly known as ST-segment depression and elevation. This can be indicative of ischemia or a heart attack.
2. Exercise Stress Testing: In an exercise stress test, patients are asked to perform strenuous physical activities while an ECG monitors the heart beat. The test can detect abnormal changes in the electrical patterns of the heart, which might be due to blocked arteries. This test serves as an initial screening method for detecting blocked arteries.
An ECG cannot operate in isolation when it comes to detecting blocked arteries. Doctors combine the results of an ECG test with the evaluation of patient’s medical history, risk factors, and symptoms to offer a comprehensive diagnosis. For instance, identifying high-risk individuals enables doctors of the best echocardiogram test in Newtown to perform additional procedures and tests to confirm the diagnosis.
So, if you experience shortness of breath, chest pain, lightheadedness, and heart palpitations, make sure to consult the doctors of the best echocardiogram centre in Newtown for an early diagnosis and treatment.
