| injections, intraventricular | Injections into the cerebral ventricles. (12 Dec 1998) |
|---|---|
| intraventricular | Injection into a ventricle. (16 Dec 1997) |
| intraventricular block | Delayed conduction within the ventricular conducting system or myocardium, including bundle-branch, peri-infarction blocks, the fascicular blocks, excitation, and the W-P-W (pre-expectation) syndrome. (05 Mar 2000) |
| intraventricular conduction | Conduction of the cardiac impulse through the ventricular myocardium, represented by the QRS complex in the electrocardiogram. H-R conduction time is from the onset of the first high frequency component of the His bundle electrogram to the onset of the QRS complex of the surface electrocardiogram (normally 43 ± 12 msec); H-V conduction time is from the onset of the first high frequency component of the His bundle electrogram to the onset of the ventricular electrogram (normally approximates the H-R interval but may be a little shorter). Synonym: ventricular conduction. (05 Mar 2000) |
| intraventricular haemorrhage | Extravasation of blood into the ventricular system of the brain. Grade Description, I GMH (bleed limited to germinal matrix), II GMH/IVH, without ventricular dilatation, III GMH/IVH leading to acute ventricular dilatation, IV GMH/IVH leading to extention into adjacent brain (21 Jun 2000) |
| intraventricular injection | The introduction of materials for diffusion throughout the ventricular and subarachnoid space by means of ventricular puncture. (05 Mar 2000) |
