ECG Exercises

Tachyarrhythmias

I. look attentively
II. wide and narrow QRS tachycardia in the same patient
III. on an attitudinal nomenclature
IV. PR<RP tachycardia
V. what to do first
VI. catch the differences
VII. widely surprised
VIII. RP < PR tachycardia with positive P waves in lead III
IX. an unusual ECG in a young male with palpitations
X. narrow tachycardia with positive P waves in inferior leads
XI. RP < PR tachycardia with P waves that are positive in inferior leads and negative and ‘w’-shaped in V1
XII. narrow QRS supraventricular rhythms

Bradyarrhythmias

I. 2nd degree AV block induced by exercise
II. exercise-induced improvement of AV conduction
III. AV conduction improvement during carotid sinus massage
IV. beware of atropine in 2:1 A-V block
V. 3 questions about one case
VI. concordant bundle branch block
VII. groups of beats separated by pauses
VIII. syncope in an old lady with a narrow QRS

Inverted T waves

I. is it myocardial ischemia?
II. is it intermittent LBBB?
III. these T waves look ischemic
IV. giant negative T-waves
V. giant negative T-waves with QT prolongation
VI. chest pain and negative T-waves deeper in V1-V2 than in V3
VII. acute chest pain and negative T-waves from V1 to V4 and beyond
VIII. what do you think of these negative T-waves from V3 to V6

Complex ECGs

I. be careful about the first impression
II. complete or 2nd degree AV block?
III. a bizarre ECG waveform
IV. analyze slowly
V. escape beats with LBBB configuration in acute inferior STEMI with AV block
VI. Wide QRS tachycardia with occasional narrower beats of different configuration

Indispensable ECGs

Indispensable ECGs
