What reason is tachycardia arrhythmia caused

summary

Tachycardia can be pathological or physiological. Pathological tachycardia also includes sinus tachycardia and paroxysmal supraventricular tachycardia. Both types of tachycardia have their own characteristics. Sinus tachycardia, for example, can be accompanied by palpitation and shortness of breath. Paroxysmal tachycardia will make the patient appear chest tightness palpitation phenomenon. Abnormal sinus node activation or slow conduction of sinus node activation can lead to arrhythmia. This is a kind of abnormal heart beat caused by heart conduction disorder.

What reason is tachycardia arrhythmia caused

First: arrhythmia can be caused by organic heart disease, such as coronary atherosclerosis, coronary heart disease, cardiomyopathy or myocarditis. In addition, rheumatic heart disease often causes arrhythmia.

Second: if people have heart failure or memory myocardial infarction, this time will also be accompanied by arrhythmia. In addition, some people may lead to arrhythmia due to autonomic nerve dysfunction, which is relatively rare. The use of anesthetics or hypothermia can also cause arrhythmias.

Third: the occurrence of premature beat may be caused by the parallel contraction of the heart, and it may also be caused by the activation of the heart. In addition, atrial lesions, such as ventricular fibroblast membrane permeability changes can cause premature beats. In addition, premature beat caused by atrial autonomic enhancement can also cause premature beat.

matters needing attention

Weidensky phenomenon can reduce the potential of the ectopic pacemaker and change the gradient of the diastolic depolarization of the ectopic pacemaker. When the above two phenomena appear, the sinus impulse reaches the ectopic pacemaker and causes premature beat.
