How to diagnosis multifocal atrial tachycardia or MAT

                           How to diagnosis multifocal atrial tachycardia or MAT


Multifocal atrial tachycardia is an irregularly irregular rhythm that is frequently associated with severe respiratory disease like decompensated  COPD , severe asthma , severe pulmonary infection.............

The irregularly irregular rhythm have 3 major dysrhythmia
      1. Atrial fibrillation
     2. Multifocal atrial tachycardia
     3. Atrial flutter with variable AV conduction
So when we see irregularly irregular rhythm we think to 3 diagnosis above , to day i will show you the EKG of Multifocal atrial tachycardia.
The pattern of this arrhythmia is
       1. Irregularly irregular RR interval 
       2. P wave precede each QRS complex
       3. at leas 3 morphorlogies of P wave ( multifocale origin of P wave )
      4. Heart rate > 100 per minute 


Here the EKG of MAT

                        

We see heart rate >100 , Irregularly irregular with differences P waves precede each QRS

Another case of MAT with exacerbation of COPD(chronic obstructive pulmonary disease)

    We apply the same criteria like above
