The first EKG shows a regular, narrow-complex tachycardia at 143 bpm. The broad term for these rhythms is supraventricular tachycardia which, if analyzed, only means a rhythm originating above the ...

Assess the differences in cardiac activation between ventricular and supraventricular tachycardias, and how these may relate to electrocardiographic changes. Discuss the electrocardiographic ...

A narrow complex tachycardia results with P wave morphologies that are different than normal sinus P waves. The QRS complex can be wide if aberrancy is present (ie, right or left bundle branch ...

A shortcut review was carried out to establish whether increasing the paper speed during ECG recording could improve the accuracy of diagnosis of narrow complex tacycardias. Altogether 256 papers were ...

The remaining physical examination was unremarkable. A lead II rhythm strip showed a broad complex tachycardia with a QRS duration of 140 ms. A lead III rhythm strip showed an apparent narrow complex ...

The term “SVT” can be confusing at times. In general, this term is used to describe a narrow complex tachycardia not including atrial fibrillation or atrial flutter. The term SVT frequently ...

The preceding rhythm is sinus rhythm. The rate of the broad-complex rhythm is slightly faster than the sinus rate but still within 10% of the rate of the sinus rhythm. This differentiates an AIVR from ...
