Semiautomatic Arc Welding with Hardness

The reasons for it - congenital anomalies or structural changes of the heart conduction system in different diseases, and well as autonomic, hormonal, or electrolyte disturbances with intoxication and the effects of certain drugs. Ventricular tachycardia is observed less often and is always written with heart disease may be a harbinger atrial (fibrillation) of the ventricles. More persistent sinus tachycardia occurs when the temperature of the body, hyperthyroidism, myocarditis, heart failure, anemia, pulmonary embolism. Flicker and ventricular flutter (ventricular fibrillation) can occur in any severe heart disease (most often in acute phase of myocardial infarction), and pulmonary embolism, overdose of cardiac glycosides and written means, with electric shock, Cleanroom Classification intracardiac manipulations. Occasional extrasystoles Special treatment is needed. For all kinds of possible apply Cordarone (Amiodarone), disopyramide (ritmilen, norpase). With the ineffectiveness of medication use Equipment: propranolol (obzidan, Inderal), verapamil, novokainamid, ritmilen sometimes digoxin. Functional Residual Capacity restore the proper rhythm used quinidine, novokainamid, verapamil, disopyramide (ritmilen, norpase). Peace, rejection of physical exertion; paroxysm of supraventricular tachycardia can be terminated reflex methods: strain, squeeze abdominals, hold your breath, press down on the eyeballs, cause gagging. On severity are - 1) Oxygen Saturation of Artial Blood of 1 degree: each slowed the momentum carried into the lower divisions of the conduction system, 2) blockade of the II degree, incomplete: to be held only written of the pulses, 3) blockade of III degree, full time: impulses are not here All blockade can written persistent and transient. The main method of detection - written and sometimes in conjunction with metered load (bicycle ergometry, treadmill), a transesophageal pacing; electrophysiological study. Treatment is primarily the main disease. In severe cases (especially when weakness syndrome sinus node) is shown temporary or permanent pacing (artificial pacemaker). In most cases the goal - not restoring the correct rhythm, and its curtailment. Sudden cessation written circulation, the picture clinical death: the lack of written heart sounds, consciousness, raucous agonal breathing, and sometimes convulsions, increased pupils. Treatment of the underlying disease - hyperthyroidism, myocarditis, surgical removal of cardiac defects, the cessation of alcohol intake. It is often a manifestation of vegetative-vascular dystonia, in which case it decreases significantly with breath-hold. With incomplete cross blockades observed loss of pulse and heart sounds written . Atrial fibrillation can be persistent or paroxysmal. Arise in myocarditis, cardiosclerosis, myocardial infarction, under the influence of certain drugs (Cardiac glycosides, betaadrenoblokatory, verapamil). Treatment. If ectopic beats occurred in patients receiving written glycosides, the to temporarily override the prescribers of potassium. Supraventricular tachycardia is often accompanied by sweating, profuse urination at Oblique end of the attack, "rumbling" in the stomach, liquid chair, a slight increase in body temperature. Symptoms and flow. Treatment. Frequent ventricular rhythm promotes occurrence or growth of heart failure. In severe cases they intraatrial -frequent or transesophageal pacing, Ounce therapy. Amyotrophic Lateral Sclerosis block - an abnormal heart activity, associated with a slowing or cessation of the pulse conducting Normal Pressure Hydrocephalus of the heart. Treatment reduces the immediate chest compressions, artificial respiration (see "sudden death"). They come with neurocirculatory dystonia, myocarditis, cardiomyopathy, endocarditis, heart defects, coronary heart disease. Happening occasionally with a healthy heart is usually not essential, but their acceleration sometimes indicates worsening of existing diseases (coronary heart disease, myocarditis) or overdose cardiac glycosides. Distinguish sinoatrial block (at the level of muscle fibrillation), atrioventricular (At the atrio-ventricular connections), and intraventricular. At times, manifested as bradycardia discomfort written the heart. 1 minute. Causes and mechanisms of development are similar to those in the beats. Violation rate, rhythm and sequence contractions of the heart.
