The dangers of non-paroxysmal atrial tachycardia are also very numerous, and the first step is to analyze the causes of non-paroxysmal atrial tachycardia. If the non-paroxysmal atrial tachycardia occurs because of the developmental problems and the conduction problems of the heart itself, it is not harmful. The heart rate is not too fast, but exceeds the atrial tachycardia of the junctional zone, but does not reach the atrial tachycardia. The heart rate is usually in the range of 100 beats per minute, and this condition is not very harmful. The other condition is pathological, such as myocardial infarction, heart failure, resulting in non-paroxysmal atrial tachycardia, which is very dangerous. It may affect the hemodynamic stability and requires active treatment of the primary disease in order to improve the arrhythmia.
