ECG QUIZ
DR.B.Gowrishankar MD pg
Prof.DR.G.Sundaramurthy’s unit(M7)
• WHAT IS THE DIAGNOSIS ?• HOW DO YOU ARRIVE AT IT ?
Features of multifocal atrial tachycardia
-different P wave morphology
-narrow complex, irregular tachycardia.
Atrial Flutter with 2:1 AV block
-flutter line
-QRS rate is half the flutter rate.
Saw tooth waveform (250-350 bpm)Irregular AV conduction
-QRS complexes conducted in 3:1 & 4:1 ratio
Non-specific intraventricular conduction delay(RsR’ complexes in II,aVF & V6.
Features of this ecg-paroxysms of atrial tachycardia rate of 150 bpm.
3:2 sinoatrial exit block
Normal QRS axis.
Ventricular tachycardia, 160 bpm, RAD +100` -wide complexes & AV dissociation
-a capture beat
-a fusion beat.
Sinus rhythm-monomorphic wide complex tachycardia.
AV Dissociation ,independent atrial activity.
Features of Inferior wall MI-deep Q waves,ST elevation & T wave inv. In leads III and aVF.-reciprocal ST depression in leads I & aVL.
Sinus rhythm –atrial ectopics.RAD, incomplete RBBB patternComplete heart block.
Acute inferior MI-ST elevation in leads II & III-reciprocal changes in leads I,V4-6.
Polymorphic VT-multiple morphologies-varying R-R intervals
Wide complex tachycardiaLAD --60`
A short R-S intervalNo AV dissociation.
