Physiologic sinus tachycardia
WebbSinus Node Reentrant Tachycardia Atrial tachycardias arising from this region are presumed to be due to microreentry in tissue near the sinus node or perinodal region (superior crista terminalis). The P-wave morphology during tachycardia should be identical to that seen during sinus rhythm. WebbThe other so-called primary sinus tachycardias, which include inappropriate sinus tachycardia, postural orthostatic tachycardia syndrome and sinus node re-entry tachycardia, have fundamentally different clinical features, basic underlying etiologic mechanisms and treatment strategies.
