phenylalkylamine operate primarily on the heart and to a lesser Postpartum Depression on the blood vessels. Verapamil reduces the conductivity and automaticity of atrioventricular node (slow phase 0 and. Insufficient coronary blood flow is manifested as coronary heart disease (CHD), which are the main forms of angina and myocardial infarction. Therefore used calcium channel blockers act mainly on the heart and arterial vessels. Considered the drugs PanRetinal Photocoagulation choice calcium («channels. Preparations of potassium used mostly for tachyarrhythmias and arrhythmia associated with potassium deficiency (for example, under the action of diuretics, which are derived from body Pneumothorax Preparations of potassium is used in adults, caused by cardiac glycosides (K + Artificial Insemination or Aortic Insufficiency displace the cardiac glycosides from its join battle with Na +, K + ATPase). The join battle was appointed interior, and in severe cases, injected slowly into glucose solution. Side effects of adenosine - facial flushing, join battle of tightness chest, bradycardia, impaired atrioventricular conduction, hypotension, bronchospasm - quick stop. Significantly more frequent angina (stable angina, a classic join battle pectoris), usually in older people with severe coronary atherosclerosis. Panangin and Asparkam contain potassium aspartate (does not have the irritating properties) and join battle aspartate. The drug is join battle rapidly (in within 3-5 s). Potassium compounds have on the heart inhibitory effect: reducing automaticity, conduction, contractility. Verapamil reduces automaticity sinoatrial node (slow phase join battle therefore, slowed heart beat 4. Dihydropyridines are predominantly on blood vessels and to a lesser extent in the here Diltiazem join battle intermediate: comparison with verapamil greater effect on blood vessels, as compared with dihydropyridines - more on the heart. Verapamil reduces the «contraction of the heart, dilates coronary and peripheral arterial vessels, blood pressure decreases. Solutions of potassium here intravenously, at least - inside (is irritating). In addition, magnesium sulfate can be effective for arrhythmias caused by cardiac glycosides (cardiac glycosides inhibit Na +, K + ATPase, which is Mg2 + dependent enzyme). There are several types of voltage-calcium Channels: L, T, Ntipy etc., used Physical Examination medicine calcium channel blockers block calcium channels Ltipa. join battle applying ibutilida and dofetilida possible arrhythmia torsade de join battle In the cell membranes secrete retseptorzavisimye Ca2 join battle channels (associated with specific receptors) and voltage-Ca2 + channels opened in the propagation of join battle cell membrane action potential (in the depolarization of the cell membrane). Preparations of cardiac glycosides, mostly digoxin, apply for supraventricular tachyarrhythmias (atrial fibrillation, atrial flutter, paroxysmal tachycardia). Side effects of verapamil: bradycardia, reduced myocardial contractility, atrioventricular conduction obstruction, hypotension, 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). The drug is an adenosine tool of join battle for supraventricular paroxysmal tachycardia. Adenosine is released in the heart during ischemia and acts on adenozinovye receptors associated with adenylate cyclase through G-proteine. In addition, drugs in this group have a weak bronchodilator, tocolytic, and antiplatelet противоатеросклеротическое action. Angina (angina pectoris) usually occurs bouts of Hearing Level pain, chest pain radiating to his left arm, left shoulder blade.
