These surface ECG characteristics are consistent with sinus tachycardia. However, considering that the patient's preoperative baseline …

A narrow QRS complex (<120 ms) reflects rapid activation of the ventricles via the normal His-Purkinje system, which in turn suggests that the arrhythmia originates above or within the His bundle (ie, a supraventricular tachycardia). The mechanism of tachycardia may be in the sinus node, the atria, the AV node, the His bundle, or some ...

WitrynaSinoatrial node reentrant tachycardia (SANRT) is caused by a reentry circuit localised to the SA node, resulting in a P-wave of normal shape and size that falls before a regular, narrow QRS complex.
