Achalasia, which is sometimes confused with acid reflux, causes problems with swallowing foods and liquids and can result in malnutrition and other serious issues. Here’s how it’s diagnosed.
A tear in the inner lining of the aortic artery can allow blood to seep between layers, impeding healthy blood flow. Doctors can now fix these “dissections” with a stent instead of open surgery.
A minimally invasive procedure called pulmonary vein ablation uses targeted energy to correct atrial fibrillation, which is a very fast, chaotic irregular heart rhythm. Here’s how the procedure works.
While extra heartbeats aren’t uncommon, sometimes they are long and sustained and signal a potentially serious issue. This can be caused by scarring from past heart attacks and other issues.
Sometimes a dangerously slow heartbeat occurs because the natural “battery” of the heart isn’t working as it should, or there’s another issue with the heart’s electrical system. Here’s how a pacemaker can help.
Almost everyone gets a feeling of extra heartbeats from time to time. While certain types of irregular heartbeats can be very serious and indicative of a serious health issue, sometimes there’s no reason for worry.
An implantable cardioverter defibrillator is an electronic device that constantly monitors your heart rhythm. This often life-saving device sends energy to the heart muscle when a very fast, abnormal rhythm is detected.
Open stent grafts provide a minimally invasive option for treating abdominal aortic aneurysms that occur above the kidneys. Learn how this works.
When all circuits are firing properly, your heart’s electrical system spreads electrical impulses seamlessly through the heart. However, sometimes an abnormality occurs that creates a block in the system. Learn how and why heart block occurs.
Your heart has its own electrical system, and like any electrical system, sometimes issues occur with the “wiring.” When this happens — usually due to a condition someone is born with — the result is an abnormally rapid heartbeat.
