When coudl a cardiovascular problem that could be diagnosed by a cardiologist using an electrocardiogram?

A cardiovascular problem that can be diagnosed by a cardiologist using an electrocardiogram (ECG) is atrial fibrillation. This condition is characterized by an irregular and often rapid heart rate, which can be detected through the abnormal electrical activity shown on an ECG. Other issues such as myocardial infarction (heart attack) and arrhythmias can also be diagnosed using this non-invasive test, providing critical information about the heart's rhythm and overall electrical function.
