First-degree heart block or AV (arterioventricular) block, or PR prolongation, is a disease of the electrical conduction system of the heart in which the PR interval is lengthened beyond 0.20 seconds.
First-degree heart block rarely causes any symptoms or problems and normally remain undiagnozed.

Time is imaginary
may be caused by rheumatic fever, some types of Heart disease and by some drugs. First-degree heart block produces no symptoms.
An artery is a pathway for the blood to travel to and from the heart. If the artery is block, the heart cannot release or receive blood, and therefore, causes heart problems.
it is not a cracked engine block it is just a loose block
One thing that I know of is " Congenital Antrioventricular Block". It CAN cause a heart to swell in size. Usually the person has irregular heart beats and eventually can need a pacemaker. I'm not saying this is what caused it in this specific question, but this is one that I know of. You should check out www.emedicine.com and look it up. It shows symptoms, causes, treatments, etc.
what are cysts on the heart caused from
Heart attacks are causes by having blockages in the arteries that surround the heart. This causes a lack of blood flow which in turn damages muscle. And is true so.......
Right bundle branch block happens less often from underlying heart disease.
An artery is a pathway for the blood to travel to and from the heart. If the artery is block, the heart cannot release or receive blood, and therefore, causes heart problems.
A blocked (occluded) coronary artery is what causes a heart attack.
No, damage to the AV node causes total heart block, in which signals from the atria fail to reach the ventricles and the ventricles beat at their own intrinsic rhythm of 20 to 40 bpm.
third degree heart block
In second-degree heart block, not every impulse reaches its destination.
Buy Some bandaids and harden up
Cholesterol can play an important part in the material that causes the blocking of blood vessels leading to thrombosis stroke and heart attack.
if you eat too much heavy things in like 3 seconds and then it just goes strait down to your heart to attack i then it suddenly blocks your heart from pumping blood i know that because i happened to me last year
it is not a cracked engine block it is just a loose block
Interruption of the impulses in the heart's conduction system is known as heart block. Heart block may be caused by scar tissue from a heart attack, among other things.
Third-degree block, also called complete heart block, is the most serious.
