The Attachment Unit Interface (AUI) is a physical and logical interface defined in the IEEE 802.3 standard for 10BASE5 Ethernet [1] and the earlier DIX standard. The physical interface consists of a 15-pin D-subminiature connector that links an Ethernet node's physical signaling to the Medium Attachment Unit (MAU), [ 2 ] sometimes referred to ...
Diltiazem has negative inotropic, chronotropic, and dromotropic effects. This means diltiazem causes a decrease in heart muscle contractility – how strong the beat is, lowering of heart rate – due to slowing of the sinoatrial node , and a slowing of conduction through the atrioventricular node – increasing the time needed for each beat.
An unusual side effect of digoxin is a disturbance of color vision (mostly yellow and green) called xanthopsia. Vincent van Gogh's "Yellow Period" may have somehow been influenced by concurrent digitalis therapy. Other oculotoxic effects of digoxin include generalized blurry vision, as well as seeing a "halo" around each point of light.
The most common indications for digoxin are atrial fibrillation and atrial flutter with rapid ventricular response, [12] [13] especially in older or less active patients, [14] though beta blockers and/or calcium channel blockers may be preferred in some patients, such as younger more active ones, or those without heart failure or hemodynamic instability.
Side effects of these drugs may include but are not limited to: Constipation; Peripheral edema, which can occur in as much as 70% of people receiving calcium channel blocker, is caused by calcium channel blockers' preferential arteriolar or precapillary dilation without commensurate dilation in the venous or postcapillary circulation.
Class III agents predominantly block the potassium channels, thereby prolonging repolarization. [2] More specifically, their primary effect is on I Kr. [3]Since these agents do not affect the sodium channel, conduction velocity is not decreased.
1,3-thiazepine 1,4-thiazepine Diltiazem. 1,4-thiazepine is the seven membered ring in the middle. Thiazepines are substituted thiepins, with a nitrogen replacing a carbon in the seven-membered heterocyclic compound. [1] Depending on the location of the nitrogen, one distinguishes 1,3-thiazepine and 1,4-thiazepine. [1]
Dantrolene may interact with the following drugs: [15] Calcium channel blockers of the diltiazem/verapamil type: Intravenous treatment with dantrolene and concomitant calcium channel blocker treatment may lead to severe cardiovascular collapse, abnormal heart rhythms, myocardial depressions, and high blood potassium.
