An ECG (electrocardiogram) is a diagnostic tool used by healthcare professionals to visualize the heart's electrical activity. Angina, a symptom of coronary artery disease, can be detected through changes in the ST segment and T-waves on an ECG. However, diagnosing angina requires a comprehensive evaluation, including medical history, physical examination, angina blood tests, and other tests.
Angina on an ECG is characterized by ST-segment depression, T-wave changes, and dynamic fluctuations in response to oxygen demand. Unstable angina can exhibit transient ST-segment changes, T-wave abnormalities, and arrhythmias. ECG findings may not always reflect angina during symptom-free periods, emphasizing the need for a multifaceted diagnostic approach involving clinical history, stress tests, and imaging. Prompt medical attention and nitroglycerin use can alleviate angina symptoms. ECG limitations include its inability to reveal structural abnormalities, intermittent arrhythmias, and other heart conditions, necessitating additional diagnostic methods for a complete assessment.
