When Is an ECG Needed?
Doctors recommend an ECG for new or unusual chest pain, especially when linked to symptoms like shortness of breath or dizziness. It's a quick, non-invasive test that can help detect heart attacks or arrhythmias. Even if the pain feels different from past episodes, an ECG provides valuable insights.
What Can an ECG Detect?
An ECG can identify irregular heart rhythms, signs of a heart attack, or other heart issues like pericarditis. Changes in the heart's electrical activity are visible on an ECG, guiding doctors in diagnosing your condition. It’s often the first step in evaluating unexplained chest pain.
Beyond the ECG
While ECGs are essential, they are just one piece of the diagnostic puzzle. Other tests like chest X-rays or stress tests may be needed for a comprehensive evaluation. Your symptoms and medical history will guide further testing.
