The most common narrow complex regular tachycardias are sinus tachycardia, atrial flutter, atrial tachycardia that blocks, and paroxysmal supraventricular tachycardia. Carotid sinus massage is useful in differentiation. Irregular narrow-complex tachycardias are usually atrial fibrillation.

Read moreHow is the QRS complex described in atrial fibrillation?
The diagnosis of atrial fibrillation is confirmed with a standard 12-lead ECG. P waves are absent, coarse “fibrillatory waves” can frequently be seen and sometimes no atrial activity can be identified. The QRS complexes are “irregularly irregular ”, with varying R-R intervals.
Read moreCan you see P waves in atrial flutter?
This is because the P waves (flutter waves) in atrial flutter occur at about 250-350 per minute (usually around 300). At this rate, it can appear that there is a P wave in front of each QRS and a T wave after each QRS . This causes the misdiagnosis of sinus tachycardia or SVT.
Read moreWhy P wave is absent in atrial flutter?
A lack of visible P waves preceding QRS complexes suggests a lack of sinus beats; this may occur with sinus dysfunction or in the presence of fibrillation or flutter waves. The P wave may also be hidden within the QRS complex. … Absence of P Waves.
