Paroxysmal Tachycardia

Multifocal atrial tachycardia, also designated "chaotic atrial tachycardia". Multifocal atrial tachycardia (MAT) is an arrhythmia with irregular atrial rate greater than 100 beats per minute (bpm). Atrial activity is well organized, with P waves in least three morphologically distinct, irregular intervals, PP, and an isoelectric baseline between P waves, the arrhythmia developed during an acute illness in 18 cases (58%). However, it occasionally occurred in paroxysms without apparent cause in patients with chronic illness. arrhythmias is not associated with digitalis toxicity or rhythm disturbances.

Chaotic atrial tachycardia arrhythmia is relatively uncommon with a prevalence rate of 0.05 to 0.32% of patients who are hospitalized. The condition is even rarer in children and young adults. Chaotic atrial tachycardia was mainly observed in males. chaotic atrial tachycardia is frequently observed in elderly patients. The causes of chaotic atrial tachycardia are mainly related diseases such as COPD, heart disease, CHF, valvular heart disease, diabetes mellitus, hypokalemia, hypomagnesemia, and azotemia. Other causes are the condition and postoperative pulmonary embolism.

The treatment of this arrhythmia involves the manipulation and / or execution of the reason rush. Oral and intravenous amiodarone (300 mg tid PO or 450-1500 mg IV over 2-24 h) was used and is effective in the transition to the natural cycle of the sinus. Metoprolol has been used to support the ventricular rate. More patients change to a natural cycle of the sinuses during treatment with beta-blockers. Esmolol may also be used to slow the ventricular rate intravenous infusion. It has a very short half-life and can be terminated quickly in the event of an adverse reactionThe goals of pharmacotherapy are to reduce morbidity and prevent complications.
