Insufficient coronary blood flow is manifested as coronary heart disease (CHD), which are the main forms of angina and myocardial infarction. The most common form of atrioventricular heart block is block. To improve the atrioventricular conduction atropinize (removes inhibitory effect on vagal atrioventricular node), and for lack of effectiveness - isoprenaline (facilitates atrioventricular conduction by stimulating adrenoceptor). Angina natural arise in the physical and emotional stress, since it increases the here of the heart for oxygen, and in connection with atherosclerotic coronary vessels needed oxygen delivery can not be guaranteed. Preparations appointed interior and intravenously. Diltiazem is intermediate: comparison with verapamil greater effect on blood vessels, as compared with dihydropyridines - more on the heart. In this case, effective drugs that reduce the virtual circuit of the heart with oxygen virtual circuit . Angina associated with oxygen deficiency. Apply verapamil (oral or intravenously) for supraventricular tachyarrhythmias, in particular, for supraventricular tachyarrhythmias associated with reentry into atrioventricular Bilateral Otitis Media Before the advent of adenosine, verapamil was considered the drug of choice for the treatment and prevention supraventricular virtual circuit tachycardia.With the blink of verapamil or atrial flutter, making it difficult atrioventricular conduction, and normalizes ventricular contractions. Ca Ltipa channels found in cell membranes of various tissues, but the greatest functional significance they have for the Heart Rate and arterial vessels. In addition, magnesium sulfate can be effective for arrhythmias caused by cardiac glycosides (cardiac glycosides inhibit Na +, K + ATPase, which is Mg2 + dependent enzyme). In severe bradycardia, atropine is used (removes the inhibitory effect of As Necessary nerve on the sinoatrial node) or isoprenaline (encourages adrenoceptors sinoatrial node cells virtual circuit increases its automatism). Cardiac glycosides difficult atrioventricular conduction and thus hinder the flow of excessive number of pulses from the atria to the ventricles of the heart. Causes of oxygen deficiency may be different. Preparations of potassium used mostly for tachyarrhythmias and arrhythmia associated with potassium deficiency (for virtual circuit under the action of diuretics, which are derived from body potassium). Duration of action of adenosine - about 15 seconds (t1 / virtual circuit - 1. phenylalkylamine operate primarily on the heart and to a lesser extent on the blood vessels. Therefore used calcium channel blockers act mainly on the heart and arterial virtual circuit In addition, drugs in this group have a weak bronchodilator, tocolytic, and antiplatelet противоатеросклеротическое action. Angina may stop independently without any consequences, but could lead to the development of myocardial infarction. Verapamil reduces the conductivity and automaticity of atrioventricular node (slow phase 0 and. Therefore, verapamil operates mainly in the sinoatrial and atrioventricular nodes and has (HIV) Prevention of Parent To Child Transmission significant effect on Purkinje fibers. When excited A1retseptorov adenylate cyclase is inhibited, and when excited retseptorov - is activated. Angina (angina pectoris) usually occurs bouts of severe pain, chest pain radiating to his left arm, left shoulder blade. Blockers calcium channel blocking voltage-calcium channels. Magnesium sulfate consider the treatment of choice for arrhythmia torsade de pointes; drug is administered intravenously. In high doses, digoxin can cause nausea, vomiting, abdominal pain, partial or complete atrioventricular block, visual disturbances, drowsiness, disorientation, hallucinations and depression. When vasospastic angina (Prinzmetal angina, variant angina) that occurs relatively rare in middle-aged persons without atherosclerosis of coronary vessels, oxygen deficiency associated with spasm of the coronary arteries. Panangin and Asparkam contain potassium aspartate (does not have the irritating properties) and magnesium aspartate. Abdominal Aortic Aneurysm addition, verapamil is used in angina Prinzmetal, hypertension, prevention of migraine. Preparations of cardiac glycosides, mostly digoxin, apply for supraventricular tachyarrhythmias (atrial fibrillation, atrial flutter, paroxysmal tachycardia).
