The electrical pathway of the heart
Heart block describes a problem with the passage of electrical signals that coordinate the heartbeat. It is different from a blockage in a coronary artery. The seriousness depends on the type and its effect on the heart rate.
Symptoms that deserve assessment
A slow heartbeat may be associated with tiredness, dizziness or fainting. Some people have no symptoms. These concerns can have several causes and need assessment rather than self-diagnosis.
How the rhythm is assessed
An ECG and, in some cases, longer-term rhythm monitoring can help identify the problem. Tell your clinician about medicines, when symptoms happen and any previous episodes of fainting.
Treatment is individual
Some findings are monitored; others need treatment, which may include a pacemaker. Your cardiologist explains the type of block, the options and follow-up. Collapse or severe associated symptoms require emergency care.
