The heartbeat is produced by an electrical signal produced in an area of ​​specialized cells in the right atrium or upper right chamber of the heart, also known as the sinus node.

The condition of heart block occurs when the electrical signals that control the heartbeat are partially or completely blocked. Common causes of heart block include heart attack, heart failure, rheumatic fever, heart disease, or cardiomyopathy (enlarged heart). However, it can also be the result of an accident during heart surgery or exposure to toxins.

The classification of heart block is first, second or third-degree, depending on the degree of alteration of the electrical signal. First-degree heart block shows no symptoms, while second and third-degree heart block reveals possible symptoms such as dizziness, fatigue, fainting, shortness of breath, and chest pain. Third-degree heart block is fatal and requires immediate medical attention due to a very slow heart rate. Therefore, it is ideal to consult a cardiology physician in case of apprehension to detect heart block in the early stages for the safety of your life. book an appoinmtnet with best cardiologist in india
