Definition

Noun: A medical condition characterized by a disruption or delay in the electrical signals that control the heartbeat, often resulting in a slow or irregular heart rhythm. This impaired conduction can lead to symptoms such as dizziness, fainting, or fatigue.

Usage

The term "heart block" is used to describe a specific type of cardiac conduction disorder. It is a technical term primarily used in medical contexts. * The patient's syncope was attributed to a complete heart block. * An electrocardiogram (ECG) is used to diagnose the degree of heart block.

Advanced Usage
  • "Atrioventricular (AV) block": This is a more precise synonym for heart block, specifying the location of the conduction impairment between the atria and ventricles of the heart.
    • The ECG findings were consistent with a first-degree atrioventricular block.
Variants and Related Words
  • Heartblock: An alternative, less common spelling of the same term.
  • Conduction defect: A broader term that encompasses heart block and other abnormalities in the heart's electrical system.
Synonyms
  • Atrioventricular block (AV block)
  • Conduction delay
  • Cardiac conduction disorder
Different Meanings

The term "heart block" has a single, specific meaning in medical terminology and is not used idiomatically or in other contexts. It does not refer to an emotional or metaphorical blockage.

Related Phrases
  • Complete heart block: A severe form where no electrical impulses from the atria reach the ventricles.
    • The implantation of a pacemaker is the standard treatment for complete heart block.
  • First-degree heart block: A mild form involving a consistent delay in signal conduction.
  • Second-degree heart block: An intermittent form where some signals fail to reach the ventricles.
  • Third-degree heart block: Another term for complete heart block.
Noun
  1. recurrent sudden attacks of unconsciousness caused by impaired conduction of the impulse that regulates the heartbeat
