The 12 lead ECG (electrocardiogram) is a quick, painless, and non-invasive test that records the electrical activity of your heart. By placing small sensors on your chest, arms, and legs, we can capture a detailed picture of your heart rhythm and rate in just a few minutes. This test is often the first step in investigating symptoms such as palpitations, chest pain, or shortness of breath, and it can help detect arrhythmias, previous heart attacks, and other cardiac conditions. Results are available immediately, allowing your cardiologist to discuss findings with you during the same visit.
