As a medical professional with expertise in cardiology, I can tell you that the accuracy of an ECG, or electrocardiogram, depends on several factors. When performed and interpreted correctly by trained professionals, ECGs are highly valuable diagnostic tools for detecting a wide range of heart conditions, including heart attacks, arrhythmias, and other abnormalities in heart rhythm or structure.
However, like any medical test, ECGs are not infallible. There can be limitations and sources of error. For instance, an ECG might not detect all heart conditions, especially in their early stages. Additionally, certain conditions or factors, such as obesity, lung disease, or even the presence of an electronic device, can interfere with the ECG's accuracy.
It's also important to note that the quality of the ECG reading can be affected by the patient's position, the cleanliness of the skin where the electrodes are placed, and the proper placement of the electrodes. Furthermore, the interpretation of the ECG requires a high level of expertise to differentiate between normal variations and actual cardiac conditions.
In summary, while ECGs are generally accurate and reliable when used appropriately, they should be considered as part of a broader diagnostic approach that may include other tests and clinical assessments.

The ECG is by far not as accurate as many patients and doctors would like to believe. Often, the findings of a measurement are completely normal even though a heart attack has taken place. As a result, ECG does not detect two out of every three heart attacks at all or not until it is almost too late.
