Summary about Heart Block

Heart block is a condition in which the heart beats more slowly or irregularly. It is caused by an issue with the electrical pulses that control how fast your heartbeats. The symptoms vary depending on the type of heart block you have. The mildest type, 1st-degree heart block, may not cause any symptoms. While 2nd-degree heart block can occasionally cause troubling symptoms that require treatment, 3rd-degree heart block, the most severe type, can be a medical emergency.
