Junctional escape beat

Index Junctional escape beat

A junctional escape beat is a delayed heartbeat originating not from the atrium but from an ectopic focus somewhere in the atrioventricular junction. [1]

Atrioventricular node

The atrioventricular node, or AV node is a part of the electrical conduction system of the heart that coordinates the top of the heart.

Atrium (heart)

The atrium is the upper chamber in which blood enters the heart.

Bradycardia

Bradycardia is a condition wherein an individual has a very slow heart rate, typically defined as a resting heart rate of under 60 beats per minute (BPM) in adults.

Cardiac cycle

The cardiac cycle is the performance of the human heart from the beginning of one heartbeat to the beginning of the next.

Dizziness

Dizziness is an impairment in spatial perception and stability.

Ectopic beat

Ectopic beat (or cardiac ectopy) is a disturbance of the cardiac rhythm frequently related to the electrical conduction system of the heart, in which beats arise from fibers or group of fibers outside the region in the heart muscle ordinarily responsible for impulse formation (i.e., the sinoatrial node).

Hypotension

Hypotension is low blood pressure, especially in the arteries of the systemic circulation.

Junctional rhythm

Junctional rhythm describes an abnormal heart rhythm resulting from impulses coming from a locus of tissue in the area of the atrioventricular node, the "junction" between atria and ventricles.

Lightheadedness

Lightheadedness is a common and typically unpleasant sensation of dizziness and/or a feeling that one may faint.

Sinoatrial node

The sinoatrial node (SA node), also known as sinus node, is a group of cells located in the wall of the right atrium of the heart.

Syncope (medicine)

Syncope, also known as fainting, is a loss of consciousness and muscle strength characterized by a fast onset, short duration, and spontaneous recovery.
