Complete Heart Block

Complete heart block is a serious condition in which patients may present with syncope and low cardiac output. Some patients may develop congestive heart failure. Diagnosis is confirmed on ECG. Symptomatic patients may require temporary pacing (TPI) followed by permanent pacemaker implantation for definitive management.

Frequently Asked Question's Abut Heart Block

What is a complete heart block?

Complete heart block is a type of heart rhythm disorder in which electrical signals from the upper chambers of the heart do not properly reach the lower chambers. This can cause the heart to beat much more slowly than normal and may affect how effectively blood is pumped through the body.

What symptoms can occur with complete heart block?

Some people may experience dizziness, unusual tiredness, breathlessness, weakness, chest discomfort, or fainting. In some cases, the condition may be discovered during an ECG even when symptoms are not obvious.

What can cause complete heart block?

Complete heart block can occur because of age-related changes in the heart's electrical system, heart disease, previous heart surgery or heart attack, certain medicines, infections, or other conditions affecting the heart. The cause is assessed individually.

How is complete heart block diagnosed?

An electrocardiogram (ECG) is an important test for identifying complete heart block by recording the heart's electrical activity. Doctors may also use an echocardiogram, blood tests, or other cardiac investigations to understand the underlying cause and assess heart function.

Does complete heart block require a pacemaker?

A pacemaker is commonly considered for people with complete heart block because it can provide electrical stimulation to help maintain an appropriate heart rate. The need for a pacemaker and the timing of treatment depend on the patient's symptoms, heart rhythm, and overall clinical condition.
