What is Heart Block?
Heart block is a condition that occurs when the electrical signals that coordinate the heart's beats are disrupted. This disruption can be partial or complete and results in a slower heart rate or irregular heart rhythms. The severity of heart block can vary, with some individuals experiencing mild symptoms while others may face significant health risks. Common heart block symptoms include fatigue, dizziness, shortness of breath, and palpitations. In more severe cases, it can lead to fainting or heart failure. Proper diagnosis and treatment are essential to manage heart block effectively and to maintain overall cardiovascular health.
