Quick ECG Testing for Early Heart Insight
An ECG (electrocardiogram) is a fast, painless test that records the heart’s electrical activity. It helps your physician understand if your heart is functioning normally or if there are early signs of disease. If you’re experiencing chest tightness, lightheadedness, fatigue, shortness of breath, or unusual heart rhythms, an ECG may be your first step toward answers.
At Advanced Cardiology, serving Katy, Sugar Land, Richmond, and the Greater Houston area, we offer advanced ECG diagnostics for early detection of cardiac conditions—often before symptoms worsen.
Led by Dr. Adnan Khalid, a board-certified cardiologist, your test results are interpreted with precision and care. Whether it’s arrhythmia, heart damage, or signs of blocked arteries, a timely ECG can change the course of your health.
