Doctors group heart block into categories based on how severe it is. This is the mildest form of heart block. The heart’s electrical signal is slowed but still gets where it’s going. These AV heart blocks include: AV 1st degree, Mobitz I (Wenckebach) 2nd Degree Type 1, Mobitz II 2nd Degree Type 2, and 3rd degree (complete heart block).

Symptoms: Most of the patients remain asymptomatic. Patients with mobitz 2 are more likely to be symptomatic than the patients with mobitz 1.The usual symptoms are lightheadedness and syncope.

A heart block is when the electrical impulses that control the beating of the heart muscle are disrupted. The most serious type of heart block known as a complete, or third degree, heart block will have symptoms, but often those with less serious heart block can have symptoms too.
Symptoms can include:
- shortness of breath
- palpitations (irregular heartbeat)
- dizzy spells/fainting
- nausea
How the heart beats
When the heart beats, the heart muscle contracts (pulls inwards) in order to pump blood around the body. The contractions are triggered by electrical impulses that are generated by a selection of specialised cells that are known as the sinoatrial node (SA node).
The SA node is often referred to as a natural pacemaker because, like artificial pacemakers, it generates a series of electrical impulses at regular intervals.
The impulse is then sent to another selection of cells that are known as the atrioventricular node (AV node). The AV node conducts the impulse into the two lower chambers of the heart (the ventricles).
A heart block occurs if the transmission of the impulse between the AV node and the ventricles is interrupted.
A heart block does not mean that the heart stops beating altogether, because other ‘back-up’ systems can take over. However, it can result in an abnormally slow heartbeat (bradycardia), leading to the body’s organs and tissue becoming deprived of oxygen.
Types of heart block
Hyperdock 1 8. There are three main types of heart block:
- first degree heart block
- second degree heart block
- third degree heart block
These are described in more detail below.
First degree heart block
A first degree heart block is where there is split-second delay in the time that it takes electrical pulses to move through the AV node. First degree heart block does not usually cause any noticeable symptoms and treatment is rarely required.
Second degree heart block
A second degree heart block is where there is a series of increasing delays in the time that it takes the AV node to send the pulse to the ventricle, until eventually a heartbeat is skipped.
There are two sub-types of second degree heart block:
Complete Heart 1 2 Commentary
- Mobitz type 1 - this is the least serious type of second degree heart block - it may occasionally cause symptoms of mild dizziness and does not usually require treatment
- Mobitz type 2 - this is a more serious type of second degree heart block - it may cause symptoms of light headedness, dizziness and fainting in some people and usually requires treatment
Third degree heart block
A third degree, or complete, heart block is where there is no transmission of electrical pulses between the AV node and the ventricles. As with second degree heart block, there are two sub-types of third degree heart block:
- congenital - where the condition is present at birth
- acquired - where the condition develops as a result of heart damage
A third degree heart block can cause a wide range of symptoms, some of which are life-threatening. This type of heart block is usually regarded as a medical emergency and may require immediate treatment with a pacemaker (an artificial electrical device that is used to regulate heartbeats).

How common are heart blocks?
First degree and Mobitz type 1 heart blocks are uncommon but not rare. It is estimated that 0.5-2% of otherwise healthy adults have these types of heart blocks.
Mobitz type 2 heart block is rare in the general population, but it is more common in people with certain heart conditions. For example, it is estimated that 1 in 30 people with heart failure will develop Mobitz type 2 heart block.
Congenital third degree heart blocks are rare, occurring in 1 in every 20,000 births.
Conversely, acquired third degree heart block is a common complication of heart disease, particularly in older people. It is estimated that 5-10% of people who are over 70 years of age, and have a history of heart disease, will develop a third degree heart block.
Conversely, acquired third degree heart block is a common complication of heart disease, particularly in older people. It is estimated that 5-10% of people who are over 70 years of age, and have a history of heart disease, will develop a third degree heart block.
Outlook
The outlook for all types of heart block is very good as long as appropriate treatment is given as and when it is required.
The most serious types of heart block respond very well to treatment with a pacemaker, and deaths that are caused by these conditions are very rare.
Heart Health 1, 2, 3, A Comprehensive Cardiovascular Disease Initiative for Diabetes Mellitus, Metabolic Syndrome and Obesity
A Comprehensive Cardiovascular Disease Initiative for Diabetes Mellitus, Metabolic Syndrome and Obesity.
In 2014, St. Mary’s Health Wagon implemented a Connections for Cardiovascular HealthSM program entitled, Heart Health 1,2,3, A Comprehensive Cardiovascular Disease Initiative for Diabetes Mellitus, Metabolic Syndrome and Obesity. This program continues today and aims to reduce the risk of a cardiac event occurring in individuals living with chronic disease and brings healthcare to patients. This program identifies individuals with metabolic syndrome, diabetes mellitus or nonalcoholic fatty liver disease (NAFLD) and correlates the risk for cardiovascular disease-related to these afflictions, therefore, minimizing and preventing the risk of a cardiac event through clinical measures and behavioral measures.
With the support of the AstraZeneca HealthCare Foundation, the Health Wagon has reached over 15,000 patients and tracked over 2,500 patients from 2014-2018 through the Heart Health 1,2,3 program.
A toolkit was created to share our program success and act as a guide for healthcare professionals who aim to alleviate the burden of chronic disease, especially as it relates to cardiovascular health. This toolkit is intended for but isn’t limited to nonprofit professionals, public health officials, and healthcare practitioners working in rural underserved areas. The program and its key components may be adapted/replicated for use in other cardiovascular health programs.
