orthodromic

 [or″tho-drom´ik]
conducting impulses in the normal direction; said of nerve fibers.

or·tho·dro·mic

(ōr'thō-drō'mik),
Denoting the propagation of an impulse along a conduction system (for example, nerve fiber) in the direction it normally travels. Compare: antidromic.

or·tho·dro·mic

(ōr'thō-drō'mik)
Denoting the propagation of an impulse along an axon in the normal direction.
Compare: antidromic

The patient's ECG is consistent with SVT associating rate-dependent LBBB which is common in orthodromic atrio-ventricular reentry tachycardias [3].
[sup][30] High frequency stimulation of the upstream (EC) and downstream (FX) structures of the hippocampus both shown to affect the spatial memory associated with the hippocampus in our study, indicating that DBS may have an impact on the neural network, which is associated with the stimulated structure in both the orthodromic and antidromic directions.
For orthodromic sensory conduction of median nerve, surface recording electrode was placed 3cm proximal to the distal wrist crease and a reference electrode at 3cm proximal to recording electrode.
Orthodromic sensory nerve conduction studies of both the median and ulnar nerves and antidromic sensory nerve conduction studies in both sural nerves were also normal.
* Orthodromic atrioventricular reciprocating tachycardia (AVRT), or Wolff-Parkinson-White syndrome, is a narrow QRS complex tachycardia in which antegrade conduction is via the AV node and retrograde conduction is via an accessory pathway (bundle of Kent).
Orthodromic response is usually triphasic along the course of sensory nerve.
Median and ulnar nerve motor conduction velocity, distal motor latency, amplitude of compound muscle action potential, median and ulnar nerve antidromic sensory conduction velocity, distal sensory latency and amplitude of sensory action potential, median nerve palm-to-wrist segment mixed orthodromic sensory conduction velocity, radial nerve antidromic sensory conduction velocity and amplitude of sensory action potential were established.
The surface of the compound eye was observed immediately thereafter under a light microscope (Nikon FX) by epi (= orthodromic) illumination.
Tracks about 100-110[degrees] at sites C and D, and about 80-90[degrees] at sites R and 5, would be consistent with orthodromic migration routes extending via Davis Strait towards oceanic areas off the coast of West Africa.
In each subject, orthodromic motor parameters of the nerve were measured.
The ulnar and median nerves were stimulated at little and index fingers respectively with pick-up at wrist (orthodromic conduction); the radial cutaneous nerve action potential was recorded at the first web space following nerve stimulation over the radial side of the forearm (antidromic conduction).
The panels show the position of the action-potential trigger zone at location 2 and orthodromic and antidromic spread of the nerve impulse from the site of initiation.
