What is heart block?
Heart block, also called AV block, is when the electrical signal that controls your heartbeat is partially or completely blocked. This makes your heart beat slowly or skip beats and your heart can’t pump blood effectively. Symptoms include dizziness, fainting, tiredness and shortness of breath. Pacemaker implantation is a common treatment.
What is the mildest heart block?
First-degree heart block: The electrical impulse still reaches the ventricles, but moves more slowly than normal through the AV node. The impulses are delayed. This is the mildest type of heart block. Second-degree heart block is classified into two categories: Type I and Type II.

What is the AV node?
The AV node is a cluster of cells that connect the electrical activity – like a bridge – from the top chambers of your heart to the bottom chambers. If you have heart block, the electrical signal does not travel through the AV node to the ventricles.
What is the difference between type 2 and type 2?
The electrical signal gets slower and slower until your heart actually skips a beat. Type II, also called Mobitz Type II: While most of the electrical signals reach the ventricles every so often , some do not and your heartbeat becomes irregular and slower than normal.
How does exercise help with heart failure?

Extends the exercise capacity of heart failure patients as measured by the distance they can walk in 6 minutes. Reduces the number of days patients spend in the hospital and the total number of hospitalizations.

Biventricular Pace Maker. The U.S. Food and Drug Administration (FDA) recently approved the first of a new type of pacemaker that paces both ventricles of the heart to coordinate their contractions and improve their pumping ability.
What is a pacemaker?
The U.S. Food and Drug Administration (FDA) recently approved the first of a new type of pacemaker that paces both ventricles of the heart to coordinate their contractions and improve their pumping ability. According to the test results presented to the FDA, cardiac resynchronization therapy (CRT): 1 Increases the amount of daily activities patient can perform without the symptoms of heart failure 2 Extends the exercise capacity of heart failure patients as measured by the distance they can walk in 6 minutes 3 Improves the overall quality of life as judged by standard measurements 4 Promotes changes in heart anatomy to improve cardiac function 5 Reduces the number of days patients spend in the hospital and the total number of hospitalizations
How do pacemakers work?
They are small devices that are implanted beneath the skin below the collarbone and connected to a pace wire (s) positioned inside the heart via a vein; this delivers a small electrical impulse to stimulate the heart to beat when it is going too slow.
What is radiofrequency ablation?
A technique pioneered at UCSF, radiofrequency catheter ablation destroys or disrupts parts of the electrical pathways causing the arrhythmias, providing relief for patients who may not have responded well to medications, or who would rather not or can't take medications.
What is the treatment for Wolff-Parkinson-White syndrome?
For conditions like Wolff-Parkinson-White syndrome, in which a hair-thin strand of tissue creates an extra electrical pathway between the upper and lower chambers of the heart, radiofrequency ablation offers a cure.
When was internal cardioversion developed?
Internal cardioversion for conversion of atrial fibrillation and atrial flutter to a normal sinus rhythm was developed here at UCSF Medical Center in 1991. Internal cardioversion is low energy electrical shock (1 to 10 joules) delivered internally in the heart through two catheters inserted in a vein in the groin and a small electrode pad applied to the chest. This procedure is performed in the electrophysiology lab by our electrophysiologist.
What is the treatment for heart block?
Treatment. For second- and third-degree heart block, you may get a small device called a pacemakerin your chest. This is considered “minor” surgery and you’ll be sedated for it. Like a backup electrical system, it reminds the heart to beat at a normal rate if it slows or stops. Life After Heart Block.
What happens when your heart beats?
Every time your heart beats, an electrical signal travels from the upper to the lower chambers. Along the way, the signal tells your heart to contract and pump blood. When that signal is slowed down or kept from sending its message, it causes a condition called heart block.
What happens when you have a heart block?
When you have heart block, the electrical signal from your heart's upper chamber slows down or gets interrupted on its way to the lower chambers. You can get mild AV block as your heart adapts to an intensive exercise routine. It's sometimes called "athlete's heart.".
What is a third degree heart block?
Third-degree. No electrical pulses will get through, which is why it's sometimes called complete heart block. Other parts of your heart, like your AV node or ventricles, will have to create their own current. But these signals are less reliable.
How does the heart work?
Your heart has four chambers that work together. They team up to pump blood through your body. An electrical signal starts out in a spot called the sinoatrial (SA) node. It's known as your heart's natural pacemaker. The current heads down to a group of cells called the atrioventricular (AV) node.
Why does my heart hurt?
Some diseases and infections can hurt your heart, like rheumatic fever, sarcoidosis, lupus, and Lyme disease. Electrolyte imbalance. Your heart may not beat normally if you don't have the right amount of minerals in your blood. AV block may happen if you have too much potassium. Heart surgery.

What is AV block?
The result: a condition called atrioventricular (AV) block or heart block. Certain health conditions, heart defects, and medicines can cause it. You might not have symptoms or need treatment. But if you do, a doctor can help you manage your condition. Without the right care, serious AV block can be life threatening.
What causes AV block?
The most common causes of AV block include: Fibrosis or sclerosis. Extra tissue can thicken, scar, and damage the pathways that send signals from the upper part to the lower part of your heart. Coronary artery disease. This damages your heart's blood vessels. It may cause AV block before or after a heart attack.
What causes a block in the heart?

What is a first degree heart block?
First-degree heart block is a condition in which the wiring of the heart is slow to send electrical signals but all of the signals are able to pass successfully. There is no electrical block but rather a slowing or delay of the signal. It usually does not cause problems. Often it does not need treatment.
