EKG Testing For Early Detection and Expert Care
An EKG is a quick, painless test that measures the electrical activity of your heart to determine how well it’s functioning. If you’re experiencing chest pain, shortness of breath, irregular heartbeat, fatigue, dizziness, swelling in the legs, or high blood pressure, an EKG can be the key to understanding what’s going on inside your heart.
At Advanced Cardiology, located at Katy and proudly serving Sugar Land, Richmond, and the Greater Houston area, we offer state-of-the-art EKG (electrocardiogram) testing as a first step in identifying heart conditions before they become critical.
With expert guidance from our board-certified cardiologist, Dr. Adnan Khalid, your EKG results will be thoroughly reviewed to determine the next steps in your heart care. Early testing can prevent serious conditions by detecting problems like arrhythmias, ischemia, or previous silent heart attacks.

Why Cardiologists Recommend an EKG
Get peace of mind with fast, accurate EKG testing in Katy, Sugar Land, and Houston—your heart health starts here. Our cardiologist recommends an EKG when patients experience symptoms that could point to heart issues. The EKG provides vital information that helps diagnose or rule out various heart conditions.
Common Symptoms That May Require an EKG:
Chest Pain or Discomfort
Why It Matters: Chest pain may be a sign of angina or a heart attack.
How EKG Helps: An EKG can detect ST-segment changes, T-wave inversions, or abnormal Q waves—classic indicators of myocardial ischemia or a heart attack. It helps determine if the pain is cardiac-related or due to another issue like reflux or muscle strain.
Shortness of Breath
Why It Matters: Could signal heart failure or reduced oxygen supply due to a cardiac issue.
How EKG Helps: It may show ventricular hypertrophy, arrhythmias, or signs of strain if the heart isn’t pumping efficiently.
Irregular Heartbeat or Palpitations
Why It Matters: May indicate arrhythmias such as AFib or tachycardia.
How EKG Helps: It records the heart’s rhythm, identifying abnormalities like AFib, SVT, PVCs, or bradycardia to guide treatment options.
Dizziness or Fainting (Syncope)
Why It Matters: Could stem from abnormal heart rhythms or sudden drops in heart rate.
How EKG Helps: Helps detect heart blocks, bradycardia, or prolonged QT intervals that could cause fainting or near-fainting.
Fatigue Without Clear Reason
Why It Matters: May be due to poor cardiac output.
How EKG Helps: Shows signs of heart damage or conduction delays that point to potential heart failure or cardiomyopathy.
High Blood Pressure (Hypertension)
Why It Matters: Chronic hypertension can damage heart structure and function.
How EKG Helps: May reveal left ventricular hypertrophy or strain patterns, which are signs of heart remodeling under stress.
Heart symptoms shouldn’t wait—visit our Katy or Sugar Land clinic for same-week EKG appointments and expert care.
What the EKG Results May Show
Heart Rhythm Problems (Arrhythmias):
EKG detects irregular, fast, or slow heartbeats like AFib or bradycardia—essential for guiding treatment, medications, or pacemaker consideration.
Previous Heart Attacks:
May show Q waves or ST changes that indicate past heart damage—even if you never had symptoms.
Poor Blood Flow (Ischemia):
ST depressions or abnormal T waves could indicate narrowed or blocked arteries. May lead to further testing like stress tests or angiography.
Heart Enlargement (Hypertrophy):
Abnormal waveforms suggest the heart is enlarged or overworked, often due to high blood pressure. Follow-up may include an echocardiogram.
Electrolyte Imbalances:
Abnormal T waves or prolonged QT intervals may indicate low or high potassium, calcium, or magnesium—important for preventing dangerous arrhythmias.
Based on the results, your cardiologist may recommend further testing or immediate treatment. Sometimes, an EKG can help prevent a serious cardiac event by catching early warning signs.
At Advanced Cardiology, we provide fast, reliable EKG testing in Katy and Sugar Land so you can move forward with confidence.
