Paroxysmal tachycardia: arrhythmia

2021-06-01 03:12 PM

Paroxysmal tachycardia is usually stopped by a vagal response. The vague nerve response induced by stimulation of the constriction of the carotid sinus is sufficient to induce a response to stop the tachycardia.

Several abnormalities in different parts of the heart including the atria, Purkinje network, ventricles, which emit pulses that spread throughout the heart can be the cause of ventricular tachycardia. This phenomenon is thought to be caused by the pathway re-receiving the “circle move” pulse, which causes repetitive self-excitation. Because tachycardia due to a single stimulus becomes the pacing site of the whole heart.

“Paralyzed” means that the heart rate becomes intermittent tachycardia, with episodes lasting a few hours or longer. The episode ends as abruptly as it began, and the pacing point of return is the sinus node.

Paroxysmal tachycardia is usually stopped by a vagal response. The vague nerve response induced by stimulation of the constriction of the carotid sinus is sufficient to induce a response to stop the tachycardia. Antiarrhythmic drugs can be used to reduce conduction or prolong the refractory period of the myocardium.
