Cardiac catheterization offers a way to look inside the heart and assess its valves and blood vessels. Most often, our board-certified cardiologists at Sunnyvale Cardiology use this minimally invasive procedure to investigate certain symptoms and diagnose heart problems — but we can also use it to facilitate further cardiac testing...

If you’ve been diagnosed with a heart rhythm disorder (arrhythmia) or severe congestive heart failure, our board-certified cardiologists at Sunnyvale Cardiology may prescribe a pacemaker. This small, implantable device emits continuous electrical pulses that keep your heart beating normally. A pacemaker can: Speed up a slow heart rhythm (bradycardia) Slow...

An arrhythmia is an abnormal heart rhythm that’s triggered by a problem with the heart’s electrical system. It can cause the cardiac muscle to beat too quickly, too slowly, or in an irregular pattern. Atrial fibrillation (A-fib) is the most common type of arrhythmia. While mild arrhythmias often self-correct and...

Atrial fibrillation, or AFib, is the most commonly treated form of arrhythmia, or irregular heartbeat. Over 5 million people in the United States are living with AFib, and more than 12 million Americans are projected to have it by 2030.  Researchers are calling AFib the “new cardiovascular disease epidemic of...

Nearly 7 million Americans are living with congestive heart failure, and about 960,000 more are diagnosed with it each year. This serious cardiovascular condition is also a leading cause of mortality, contributing to 1 in 9 adult deaths in the United States.  Despite its name, heart failure doesn’t mean that...

When it comes to your health and longevity, an ounce of prevention is worth a pound of cure. This is especially true when it comes to the health of your cardiovascular system — the vital body system that drives and supports all other aspects of your physical function and vitality. ...

Peripheral artery disease (PAD) occurs when the blood vessels in your legs (and sometimes in your arms) are narrowed and hardened by atherosclerosis — or the accumulation of sticky plaque deposits in the walls of the vessels that carry blood to your extremities.  When it’s spotted early, this progressive condition...

Your heart’s electrical system is a network of cells and nodes that generates and delivers the electrical impulses that coordinate the organ’s pumping action. When something goes wrong with this “cardiac conduction system,” you may need a pacemaker to rectify the problem.  At Sunnyvale Cardiology in Sunnyvale, Texas, our cardiologists...

An electrocardiogram is a simple, noninvasive diagnostic test that measures and records your heart’s electrical activity — a central marker of normal heart function and health. Also called an ECG or EKG, this gold standard cardiovascular evaluation tool provides helpful insight about how well your heart is working. At Sunnyvale...

A stress test measures cardiac function while you exercise on a treadmill or stationary bike. This standard, noninvasive evaluation shows how well your heart works when it’s pumping harder during physical exertion, making it easier to identify cardiac problems and certain forms of heart disease. At Sunnyvale Cardiology in Sunnyvale,...

The amount of sleep you get each night can affect your heart health! Studies published in the Journal of the American College of Cardiology show that getting between six and nine hours of sleep each night can offset genetic risks for heart attacks. Click here to learn more about this...

As you age, it's important to stay on top of your health to detect different conditions. Chances for developing coronary artery disease specifically increases as we age! Men over the age of 45 and women over the age of 55 have a greater risk for coronary artery disease. Make sure...

For those who experience symptoms of a heart condition, cardiac catheterization helps to diagnose the condition. It's an imaging procedure used by Sunnyvale Cardiology to evaluate heart function or enhance another heart procedure. Learn more.https://www.sunnyvalecardiology.net/services/cardiac-catheterization/

Some of the early signs of a heart attack include chest discomfort, upper body discomfort, shortness of breath, and nausea. It's essential to call 911, even if you're not sure it's a heart attack! It's best to get these symptoms checked out to ensure that you are healthy. 

Atrial fibrillation can cause a heart attack or stroke, making early detection and treatment crucial. At Sunnyvale Cardiology in Sunnyvale, Texas, cardiologists Prasad Maddukuri, MD, FACC, MRCP, Saleem H. Mallick, MD, FACC, and Larry Moore, MD, FACC.  Atrial fibrillation is a heart arrhythmia, or a problem with the speed or...

Heart Health Screening Q & A What is a heart health screening? A heart health screening is a preventive tool designed to ensure your heart stays healthy. Certain factors significantly increase your risk of heart disease. Knowing those factors — and how to mitigate them — can make all the...

What is congestive heart failure? Congestive heart failure, also known as heart failure, occurs when your heart can’t pump blood efficiently enough to meet your body’s demands. Your heart hasn’t stopped working, but it isn’t functioning properly. Symptoms of congestive heart failure include: Tiredness or severe weakness Shortness of breath...

Exercise stress testing is used to determine how well your heart handles its workload. It is primary used to determine if your heart receives enough oxygen and proper blood flow when it is under stress such as when you are exercising. The test usually employs the “Bruce” protocol, Exercise is...

Cardiac catheterization (or coronary angiogram) is a procedure used to diagnose and treat cardiovascular disease. Cardiac catheterization provides information on how well your heart works, identifies problems and allows for procedures to open blocked arteries. During cardiac catheterization, a long thin tube called a catheter is inserted in an artery...

This is an echocardiogram that is performed in combination with Exercise stress testing. This test can be used to visualize the motion of the heart’s walls and pumping action when the heart is stressed. It may reveal a lack of blood flow that isn’t always apparent on other heart tests.
