Which condition Cannot be detected by ECG? ›

Valvular defects cannot be detected using an ECG. Chest X-ray can be used to determine such defects. Therefore, an ECG can detect arrhythmia, myocardial infarction and also heart block but not valvular defects.

Valvular defects are not detected by ECG.

An ECG is a great test to analyse heart signals and can directly or indirectly help spot heart blockages or artery issues.

The atrial repolarization cannot be identified on an ECG tracing because it is hidden behind the QRS complex. Lastly, the T wave represents ventricular repolarization, in which the ventricles are relaxed, recharging and filling with blood.

Which of the following conditions are detected by the ECG? From the ECG it is possible to detect abnormal heart rhythms, conduction problems, and the location of damaged heart muscle.

An electrocardiogram (ECG) can help recognize types of angina and other serious heart problems. Certain ECG patterns can be a sign of unstable angina or vasospastic angina. However, your ECG may sometimes be normal even if you have angina.

Atrial Septal Defect

As a result, blood flow to the lungs increases. Small holes in the septum can go undetected until adulthood.

An echocardiogram can show how blood moves through the heart and heart valves. Parts of the heart that move weakly may be caused by a lack of oxygen or a heart attack. This may be a sign of coronary artery disease or other conditions. Exercise stress test.

There is no distinctly visible wave representing atrial repolarization in the ECG because it occurs during ventricular depolarization.

What could show up on an ECG? ›

An ECG can help detect: arrhythmias – where the heart beats too slowly, too quickly, or irregularly. coronary heart disease – where the heart's blood supply is blocked or interrupted by a build-up of fatty substances. heart attacks – where the supply of blood to the heart is suddenly blocked.

Exercise or smoking before the test. Certain medicines. Electrolyte imbalances, such as too much or too little potassium, magnesium, or calcium in the blood.

You may have trouble breathing, an irregular heartbeat, swollen legs, neck veins that stick out, and sounds from fluid built up in your lungs. Your doctor will check for these and other signs of heart failure. A test called an echocardiogram is often the best test to diagnose your heart failure.

A CT coronary angiogram can reveal plaque buildup and identify blockages in the arteries, which can lead to a heart attack. Prior to the test, a contrast dye is injected into the arm to make the arteries more visible. The test typically takes 30 minutes to complete.
