reentry

 [re-en´tre]
in cardiology, reexcitation of a region of cardiac tissue by a single impulse, continuing for one or more cycles and sometimes resulting in ectopic beats or tachyarrhythmias; see also circus movement.
atrioventricular (AV) nodal reentry an arrhythmia-causing mechanism in which two opposing pathways are established within the atrioventricular node (longitudinal dissociation); the anterograde pathway, which is usually slower, activates the ventricles and the retrograde pathway, which is usually faster, activaties the atria. This mechanism is responsible for approximately half of symptomatic paroxysmal supraventricular tachycardias.

re·en·try

(rē-en'trē),
Return of the same impulse into a zone of heart muscle that it has recently activated, sufficiently delayed that the zone is no longer refractory, as seen in most ectopic beats, reciprocal rhythms, and most tachycardias.

re·en·try

(rē-en'trē)
Return of the same impulse into a zone of heart muscle that it has recently activated, sufficiently delayed so that the zone is no longer refractory, as seen in most ectopic beats, reciprocal rhythms, and most tachycardias.

(8) Reentry into the atmosphere at these speeds would generate a shock wave in which the atmosphere is heated to many thousands of degrees, even approaching 12,000 F, which exceeded the melting point of tungsten, the metallic element with the highest known melting point, 6,116 degrees Fahrenheit.
Before discussing individual test and operational reentry vehicles, a brief discussion of testing methods, both for ground and flight is necessary.
(73) But the trend of reentry courts in recent years as a response to the unforgiving legacy of the sanction-driven War on Drugs is a hopeful transformation.
As noted, judges are in a prime position to lead, and their involvement in the reentry court model has been effective.
Although reentry is often discursively positioned as opposing mass imprisonment, arguments that fundamentally question punishment are foreclosed.
Ultimately, reentry reforms posit that we can have imprisonment and rehabilitation in the service of a cost-efficient punishment system.
This new reentry device enabled successful performance of EVT for this tough CTO lesion.
The 0.035-inch wire was not in the true lumen, however, so we subsequently used a reentry device called an Outback Elite catheter (Cordis, Florida, USA) to attempt to gain access to the true lumen.

(125.) See generally BOAR & WATLER, supra note 14, at 15 (explaining that sanctions should be proportional to the violation and consistently applied); FAROLE, supra note 89, at 8, 12 (stating that reentry court planners, as well as community representatives, discuss what are appropriate and effective sanctions and incentives; and also that the sanctions should be relevant to the offender).
