What is ectopic tachycardia?With regard to heart disease

Ectopic tachycardia is a burst or continuous attack quickly and the basic rules of the ectopic rhythm, its sudden onset and termination of most of the past had been known as paroxysmal supraventricular tachycardia (paroxysmal tachycardia). Heart attack General 160 ~ 220 times / min, but there are also slow to 130 times / min or faster than 300 times / min's. Each attack sustainable than one seconds or continuing a few seconds, a few hours, a few hours or even days, automatically or after treatment termination. Was part of a recurring problem, the attack space of varying lengths.

Originated from the Greek branch of the Secretary-beam above the site of the tachycardia are collectively referred to as supraventricular tachycardia, ECG QRS wave attack mostly widened; Secretary beam into the sky from the Greek branch of the following sites are known as tachycardia ventricular tachycardia, attack mostly abnormal electrocardiogram widened QRS wave. However, the clinical electrophysiology study has confirmed a small number of the widened QRS tachycardia is tachycardia, and a very small number of ventricular tachycardia attack QRS not widened, resulting in tachycardia and ventricular tachycardia in the differential diagnosis Sometimes it is difficult to determine, which have wide-QRS tachycardia with narrow QRS tachycardia known. Supraventricular tachycardia of the more common than ventricular.

Over the past 20 years of ectopic tachycardia in a large number of research findings, has deepened its mechanism, electrocardiogram performance awareness and promote their classification, diagnosis and treatment updates.
