Percutaneous Transhepatic Cholangiography vs Oral Contraceptive Pill

Verapamil reduces the «contraction of the heart, dilates coronary and peripheral arterial vessels, secund pressure decreases. Side effects of verapamil: bradycardia, reduced myocardial contractility, Premature Baby conduction obstruction, secund dizziness, statement, peripheral edema, especially ankle edema (associated with selective expansion of arterioles and prekapillyarov; in arteriovenous shunts widen the artery but not vein, inadequate venous outflow). Ca Ltipa channels found in cell membranes of various tissues, but the greatest functional significance they have for the hearts and arterial vessels. Angina may stop independently without any consequences, but could lead to the development of myocardial infarction. In applying ibutilida and dofetilida possible arrhythmia torsade de pointes. The action of adenosine is due mainly to difficulty of atrioventricular conduction (adenosine stimulates adenozinovye A receptors, with a G-proteine inhibited adenylate cyclase and activate K + channels). In severe bradycardia, atropine is used (removes the inhibitory effect of vagus nerve on the sinoatrial node) or isoprenaline (encourages adrenoceptors sinoatrial node cells and increases its automatism). Magnesium sulfate consider the treatment of choice for arrhythmia torsade de pointes; drug is administered intravenously. Therefore used calcium channel blockers act mainly on the heart and arterial vessels. Preparations appointed interior and intravenously. In addition, secund in this group have a weak bronchodilator, tocolytic, and antiplatelet противоатеросклеротическое action. Angina associated with oxygen deficiency. More appropriate to prevent attacks angina. When vasospastic angina (Prinzmetal angina, variant angina) that occurs relatively secund in middle-aged persons without atherosclerosis of coronary vessels, oxygen deficiency associated with spasm of the coronary arteries. In high doses, digoxin can cause nausea, vomiting, abdominal pain, partial or complete atrioventricular block, visual disturbances, Natural Killer Cells disorientation, hallucinations and depression. blockers for vasospastic angina is not recommended, as it blockers narrow the coronary vessels. If you blink (atrial fibrillation), atrial (tahiaritmicheskaya shape) of digoxin does not eliminate the arrhythmia in the atria, but secund to difficulties slowed atrioventricular conduction (normalizes) ventricular (translates tahiaritmicheskuyu atrial fibrillation in normosistolicheskuyu). The drug is injected rapidly (in within 3-5 s). Heart block called conduction disturbances of the heart conduction system. Causes of oxygen deficiency may be different. According to the chemical structure Platelets calcium channel blockers distinguish: phenylalkylamine - verapamil, gallopamil; benzotiazepiny - diltiazem, dihydropyridines - nifedipine, amlodipine, izradipin, felodipine, nitrendipine, nizoldipin, nicardipine, etc. Therefore, each angina need as quickly as possible (in minutes) to stop (to arrest).
