When should I see a non-interventional cardiologist?
Not all heart concerns require procedures. While interventional cardiologists focus on performing minimally invasive treatments like stents or valve replacements, non-interventional cardiologists specialize in the prevention, diagnosis, and medical management of heart disease.
Your doctor may refer you to a cardiologist if you experience symptoms such as chest pain, palpitations, shortness of breath, dizziness, or irregular heartbeats. You may also be referred if you have risk factors such as high blood pressure, high cholesterol, diabetes, or a family history of cardiovascular disease.
Our cardiology team provides comprehensive care through diagnostic testing, medication management, and lifestyle guidance—helping patients protect their heart health and reduce the need for procedures whenever possible.
We welcome patients through self-referrals as well as referrals from primary care physicians and other specialists.

FAQs
Recognizing heart attack symptoms early is crucial. Common signs include chest pain or discomfort (pressure, squeezing, or fullness), shortness of breath, upper body pain (arms, back, neck, jaw, or stomach), nausea or vomiting, cold sweats, and dizziness. If you or someone else experiences these symptoms, seek immediate emergency medical attention.
Atrial Fibrillation (AFib) is an irregular heart rhythm that increases stroke risk. Treatment options include medications to control heart rate and prevent blood clots, cardioversion to reset the heart's rhythm, and catheter ablation to destroy abnormal heart tissue. Lifestyle changes, such as stress management and maintaining a healthy weight are also important. In some cases, a pacemaker may be implanted. Early diagnosis and treatment of AFib can prevent complications.
Pacemakers are used for conditions that cause the heart to beat too slowly, irregularly, or with dangerous pauses. They help regulate rhythm, maintain steady blood flow, and reduce symptoms like fatigue, dizziness, or fainting.
Heart Conditions That May Require a Pacemaker:
- Bradycardia – when the heart beats too slowly.
- Heart block (AV block) – when electrical signals between the upper and lower chambers of the heart are delayed or blocked.
- Sick sinus syndrome – when the heart’s natural pacemaker (sinus node) doesn’t work properly, causing alternating slow and fast rhythms.
- Atrial fibrillation with slow ventricular response – when AFib causes the lower chambers of the heart to beat too slowly.
- Congenital heart disease – some people are born with electrical system abnormalities that require pacing support.
- Post–heart surgery or heart attack rhythm problems – when the heart’s electrical system is damaged and doesn’t recover.
Recent advancements in heart disease treatment include minimally invasive procedures like TAVR, advanced imaging technologies for earlier diagnosis, wearable health devices for real-time monitoring, personalized medicine, regenerative therapies, robotic surgery, and expanded access through telemedicine.
