AVJT

This is part of: Supraventricular Rhythms

AV junctional tachycardia / Junctional Ectopic Tachycardia (JET)
{{{locatieafbeelding}}}
Atrial rate	60-100 bpm
Ventricular rate	70-130 bpm
Regularity	regular
Origin	AV node
P-wave	RP > RP
Effect of adenosine	slows down heartrate
Example ECG: Lead II shows competition between the sinus rate and the nodal tachycardia. After around the third beat, some sinus beats are conducted and followed by QRS complexes. Thereafter the nodal tachycardia takes over resulting in a negative p-wave around the 8th beat, the proof of a junctional rhythm.
