O que (quem) é antidromic - definição

Antidromic conduction; Antidromal; Antidromic response

antidromic         
[?ant?'dr??m?k]
¦ adjective Physiology (of an impulse) travelling in the opposite direction to that normal in a nerve fibre. The opposite of orthodromic.
Origin
early 20th cent.: from anti- + Gk dromos 'running' + -ic.
Antidromic         
An antidromic impulse in an axon refers to conduction opposite of the normal (orthodromic) direction. That is, it refers to conduction along the axon away from the axon terminal(s) and towards the soma.
Supraventricular tachycardia         
  • Atrial fibrillation: Red dots show atrial fibrillation activity.
  • A 12-lead ECG showing paroxysmal supraventricular tachycardia at about 180 beats per minute.
  • Mechanisms of supraventricular tachycardias
ABNORMALLY FAST HEART RHYTHM ARISING FROM IMPROPER ELECTRICAL ACTIVITY IN THE UPPER PART OF THE HEART
Tachycardia, supraventricular; AV re-entrant arrhythmia; Narrow complex tachycardia; Narrow QRS complex tachycardia; Narrow QRS tachycardia; Supra Ventricular Tachyardia; Orthodromic AVRT; Antidromic AVRT; Sinoatrial node reentrant tachycardia; Circus movement tachycardia; Junctional reciprocating tachycardia; Persistent junctional reciprocating tachycardia; Supraventricular takycardia; Supraventricular arrhythmia
Supraventricular tachycardia (SVT) is an umbrella term for fast heart rhythms arising from the upper part of the heart. This is in contrast to the other group of fast heart rhythms – ventricular tachycardia, which start within the lower chambers of the heart.

Antidromic

An antidromic impulse in an axon refers to conduction opposite of the normal (orthodromic) direction. That is, it refers to conduction along the axon away from the axon terminal(s) and towards the soma. For most neurons, their dendrites, soma, or axons are depolarized forming an action potential that moves from the starting point of the depolarization (near the cell body) along the axons of the neuron (orthodromic). Antidromic activation is often induced experimentally by direct electrical stimulation of a presumed target structure. Antidromic activation is often used in a laboratory setting to confirm that a neuron being recorded from projects to the structure of interest.
