First-degree AV block is not considered a “true blockage,” but rather a slowing of electrical conduction between the atria and the ventricles. It differs from second- or third-degree AV block, where some — or even all — impulses fail to pass through the AV node.
Atrioventricular blocks (AV blocks) are delays or interruptions in the electrical signal traveling between the atria and the ventricles. This pathway, controlled by the AV node — the heart’s “electrical gatekeeper” — can be slowed to varying degrees.
Three degrees of AV block are recognized, ranging from a simple delay to a complete interruption of the signal.
The heart never takes a vacation. Even during the summer, cardiovascular diseases remain a concern. Chest pain, shortness of breath, fainting, heart failure, high blood pressure, or forgetting to take prescribed medications should never be ignored. Learn the essential precautions to take before and during your vacation, the warning signs that require prompt medical attention, and the healthy habits that can help you travel safely while living with cardiovascular disease.
A chronic total occlusion (CTO) is a coronary artery that has been completely blocked for several months. Learn about its symptoms, diagnostic tests, risks, and the treatment options available to reopen the artery and improve quality of life.
Pericarditis is an inflammation of the sac surrounding the heart, often caused by a viral infection. It typically causes chest pain and usually resolves without long-term consequences. Fluid may sometimes accumulate around the heart and requires monitoring, but treatment is generally straightforward and recovery is usually complete.
This sage parsnip ravioli is served with a beet and turnip carpaccio enhanced by an orange vinaigrette. A colorful and elegant recipe created by Chef Philippe Laloux.
Most of the treatments used today are the result of clinical research. By participating in a clinical study, patients help advance medical knowledge and improve the care that will be available to future generations.
Palpitations, dizziness, atrial fibrillation, Apple Watch, KardiaMobile, Cardiomemo, or extended Holter monitoring: several technologies are now available to monitor the heart’s electrical activity over extended periods. Learn how these different external cardiac monitoring systems work, their advantages, limitations, and their role in diagnosing heart rhythm disorders.
A sedentary lifestyle related to desk work is an important risk factor for cardiovascular disease. Risk factors do not simply add together — they interact and amplify one another, increasing the risk of heart attack and stroke. Simple changes, repeated over time, can lead to lasting improvements in health.
Ivabradine (Lancora™) is a medication used in certain forms of heart failure to slow the heart rate. Learn how it works, its benefits, possible side effects including phosphenes, and the precautions associated with this treatment.
