Heart rhythm disturbances - Arrhythmia
Heart rhythm disturbances called arrhythmias expertly among the most common heart disease. They arise as a consequence of a different formation or conduction of electrical impulses in the heart. Hearts are normally downloads a 60-100krát per minute when the first contraction occurs atria and then the ventricles. This rhythm is called sinus. Sometimes, even in healthy people the heart works more slowly (e.g., sleep) or rapidly (eg during exercise). When cardiac arrhythmias, heart rhythm is either irregular or abnormally slow or fast vice versa. In most cases, it is a completely non-fatal arrhythmia, which affected person is unaware and which can be captured only long-term electrocardiogram monitoring. Furthermore, though there are numerous seizure or persistent cardiac arrhythmias, which can cause the patient considerable difficulties. Whereas in otherwise healthy people constitute arrhythmia exceptions immediate threat to life in patients with heart disease (e.g. myocardial infarction) may be some lethal arrhythmias.
What are the symptoms of arrhythmia?
Symptoms of slow heart rhythms (bradyarrhythmias) may vary depending on what the fault is and how quickly arises. In cases where the heart works slowly and fails to accelerate its activity during exercise, the patient suffers from vertigo, dizziness or increased zadýcháváním and tiredness. If the heart rate at rest is very slow or present a few seconds of attacks in the creation of electrical impulses, may even short-term loss of consciousness. If there is fault sequentially or if transient, symptoms may be only insignificant (for example, dizziness, fatigue etc.). It will be appreciated that similar symptoms may be caused by a variety of other diseases (e.g. epilepsy, stroke, etc.), And therefore, professional judgment of the situation lékařem.Nejčastějším flagged when an abnormally rapid heart rate (tachyarrhythmia) palpitations. It is an unpleasant feeling of perceived rapid or strenuous palpitations. In many cases it is only "hiccup" or "missed" heartbeat. The basis of such rhythm disorders are known. Extrasystoles or premature contractions coming. The most common sustained tachyarrhythmia is called. Atrial fibrillation, which occurs in the atria of normal fault propagation of electrical impulses, and these circles after many varying circuits. An irregular and rapid transfer of such impulses to ventricular arrhythmias such as felt differently rapid and irregular heartbeat, sometimes accompanied by increased tiredness or shortness of breath. For other types of arrhythmias difficulties manifest regular bouts of rapid heartbeat. These forms of seizure usually have a sudden onset and termination. They are often accompanied by a feeling of tightness, shorter of breath or weakness to short-term loss of consciousness.
It will be appreciated that there is a direct relationship between the severity of the arrhythmia and its perception. In other words, absolutely meaningless rhythm disorder that the patient does not life-threatening, it can be subjectively perceived very uncomfortable and prevent the patient a normal life, while more serious arrhythmia may be virtually perceived.
What are the treatment options to manage arrhythmias?
Currently, the most common method of treatment a slow heartbeat pacemaker implantation. This exercise is performed from a small skin incision below the collarbone, where through subclavian vein is introduced into the heart of a thin flexible electrode. This is then connected to a pacemaker, which are sown in a pre-created small pockets in the skin. After wound healing is another control and programming the pacemaker happen transmitting radio waves from the programming device through the skin. Continuing technical progress enables the most pacemakers mimic the normal activity of the heart and in case of failure of the formation of normal impulses in the heart of the heart to stimulate proportion to the degree zátěže.Oproti bradyarytmiím featured treatment of rapid heart rhythms, until recently a major problem. Although a wide variety of tachyarrhythmias can be effectively discontinue use of some medicines used to treat arrhythmias (ie. Antiarrhythmics) or an electric shock from a defibrillator for short-term suspend patient (shock discharges across the heart and allows the resumption of normal electrical activity of the heart), more difficult to prevent a repeat disorders rhythm. Real coup brought the introduction of new methods for removal of cardiac arrhythmias using the so-called. Ablation. In this exercise are running through a blood vessel in the groin to the heart introduced special thin electrode catheters (similar long flexible trubičkám diameter of about 2 mm) and placed so that they can sense electrical signals from the individual chambers of the heart. Then use the analysis of the recorded electrical signals to pinpoint the area of heart tissue, which is involved in the formation and maintenance of arrhythmia. It is mostly small precinct of the heart muscle, which for some reason gives rapid electrical pulses or an electrical impulse which circles around. This site may be using a special steers
