About Atrial tachycardia disease
Atrial tachycardia (atrial tachycardia) is defined by various types of tachycardia. Atrial tachycardia is one of the most common diseases of the circulatory system. t is estimated that atrial tachycardia is responsible for 10% – 15% of cases of tachycardia at an advanced age. This phenomenon is associated with structural diseases of the heart muscle and ischemic heart disease, which appears after various operations in the heart, and following chronic obstructive pulmonary disease (Chronic Obstructive Pulmonary Diseases), an imbalance in the electrolytes or electrolytes Prescription drugs, especially digoxin, note that atrial tachycardia occurs occasionally, even in people who are not sick.
Atrial tachycardia often occurs in the form of seizures but, in some cases, tachycardia is inherent. People with this condition often complain of the following symptoms: palpitations – a feeling of heartbeat, rapid pulse, anxiety, shortness of breath, chest pressure and sometimes dizziness and fatigue. Atrial tachycardia is classified according to the mechanisms of the phenomenon: Intraatrial reentry, automated atrial tachycardia, and atrial tachycardia caused by the presence of a stimulating agent (Triggered atrial tachycardia).
1. Intra atrial reentry: This condition affects people with primary heart disease or impairment of the speed of heart systems originating in the atria, such as cases of atrial flicker or atrial flutter. The mechanism of this phenomenon is not entirely clear, but the speed of the heartbeat is between 120 and 240 beats per minute. In general, the ratio of the pulse rate between the atrium and ventricle is two to one (2: 1) in such a way that it does not show any signs of disease or, in extreme cases, it is accompanied by slight signs. It is sometimes difficult to distinguish them from other arrhythmias. In some cases, drug therapy is a contributor to diagnosis, such as adenosine, which blocks the AVN blocker. Accurate diagnosis is made by electrophysiologic testing and then ablation by radio frequency. The success rate for this type of treatment is approximately 75%. Anti-arrhythmic treatments are not effective.
2. Automated atrial tachycardia: This condition usually occurs when there is external stimulation of the ventricle, ie it does not stem from the sinus node (sinus node). It may have originated from the right atrium or the area of the pulmonary veins on the left atrium. The mechanism of this phenomenon is not clear enough. This phenomenon is commonly found in people with a warm-up phenomenon, known as cardiac tachycardia after it has started. This condition of tachycardia is not affected by stimulation from the vagus nerve (Nervus vagus) and often tachycardia is continuous or permanent. Drugs from the family of beta-blockers, such as Propranolol, are effective treatments to reduce atrial tachycardia. Adenosine is useful in the treatment of cardiac tachycardia temporarily and rarely stops the phenomenon completely. Verapamil, which belongs to the group of drugs blocking the calcium channel, is not considered an effective treatment for the phenomenon. The next treatment for this type of permanent atrial tachycardia is by ablation using radio waves.
3. Atrial tachycardia caused by an external stimulus (Triggered atrial tachycardia): This type of tachycardia is less prevalent than the previous types and usually appears in older patients. Hypersensitivity to sympathetic nerve stimuli is usually the beginning of this type of tachycardia. This condition is treated with adenosine medications or drugs that fall under the group of calcium channel blockers such as Verapamil. Also, ablation using radio waves is the preferred treatment.
