Also known as atrioventricular block, heart block is a condition where the heart beats too slowly. It occurs within the heart’s electrical system where the signals that command the heart to contract are partly or completed blocked between the upper and lower chambers. There are three types of heart block: First-degree heart block Second-degree heart block or Wenckabach block Third degree heart block or Complete block
The symptoms experienced due to this condition depend on the type of heart block you have. First-degree heart block may not cause any signs and symptoms. Whereas symptoms of second and third-degree heart block include: Fainting Chest pain Shortness of breath Dizziness Fatigue
Some common causes of heart block are: Heart attacks Complication of lyme disease Infection of the heart valves Sarcoidosis or hemochromatosis Scarring of the heart’s electrical system
Even if you are not experiencing any symptoms, heart block is generally diagnosed during routine tests. Moreover, your cardiologist will review your complete family and medical histories to suggest some tests for further examination of your condition. Electrocardiogram (ECG) Holter and event monitors Physical exam Electrophysiology study
Treatment depends on the kind of heart block you have. You may not require treatment for first-degree heart block. But cases of second and third-degree heart block need to be treated regardless of the severity. You may be asked to lower the dosage of a certain medicine if it is the main cause for your heart block. Pacemaker A pacemaker detects an abnormal heart rate and then it releases electrical impulses that recondition the heart to beat at a normal rate. Transcutaneous pacing It is a temporary means of pacing a victim’s heart and should be initiated without delay.
