SVT or PSVT is a regular rythm but accelerated rate.


MAT : Irregular rythm. each QRS is preceeded by a P wave which is morphologically abnormal bec it does not arise from the SA node

AF: Irregular ryhtm. Not all P waves are followed by QRS there is a degree of heart block

Multifocal atrial tachycardia:3 or more P-waves of variable morphology and varying P–R intervals, plus tachycardia, which is a heart rate exceeding 100 beats per minute. Narrow QRS complexes are visible as well.

It is more common in the elderly.


It is most commonly associated with hypoxia and COPD
