ECG Patterns Flashcards
What rhythm is seen here?
MONOMORPHIC VENTRICULAR TACHYCARDIA
(Regular broad complex tachycardia)
What rhythm is seen here?
ATRIAL FIBRILLATION
(No P waves, irregularly irregular QRS, ragged baseline)
What rhythm is seen here?
SINUS ARRHYTHMIA
(All the features of sinus rhythm but the R-R interval is irregular)
What rhythm is seen here?
ATRIAL FLUTTER
(F waves, regular QRS, ventricular rate divisible by 300, ‘saw tooth’ pattern)
What rhythm is seen here?
POLYMORPHIC VENTRICULAR TACHYCARDIA
(Broad complex tachycardia, often associated with prolonged QT)
What rhythm is seen here?
JUNCTIONAL RHYTHM
(Normal QRS morphology with retrograde P waves)
What rhythm is seen here?
SINUS RHYTHM
(Every P wave is followed by a QRS, with a PR duration of < 200ms)
What rhythm is seen here?
SUPRAVENTRICULAR ECTOPICS
(Sinus rhythm, differing P wave morphology every 3 beats)
What rhythm is seen here?
VENTRICULAR FIBRILLATION
(Irregular random baseline with no clear waveforms)
What rhythm is seen here?
SUPRAVENTRICULAR TACHYCARDIA
(Regular, narrow complex tachycardia, often no clear P waves)
What rhythm is seen here?
1ST DEGREE HEART BLOCK
(PR prolongation)
What rhythm is seen here?
MOBITZ 1 HEART BLOCK
(Progressive PR prolongation until there is a dropped beat)
What rhythm is seen here?
MOBITZ 2 HEART BLOCK
(Every second QRS dropped)
What rhythm is seen here?
3RD DEGREE HEART BLOCK
(No relationship between P waves and QRS complexes)
What vascular territory is highlighted in blue?
Which artery does this correspond to?
Lateral
Left circumflex artery
What vascular territory is highlighted in green?
What artery does this correspond to?
Inferior
Right coronary artery
What vascular territory is highlighted in red?
What artery does this correspond to?
Anterior
Left anterior descending artery
What can be seen in this ECG?
What pathology is this suggestive of?
ST elevation in leads V1-V4, suggestive of an anterior MI affecting the left anterior descending artery
What can be seen in this ECG?
What pathology is this suggestive of?
ST elevation in leads II, III, aVF and V5/V6, suggestive of an inferior and lateral MI affecting the right coronary artery and left circumflex artery
Which type of bundle branch block is seen in this ECG?
Right bundle branch block
(+ left axis deviation = bifascicular block)
Which type of bundle branch block is seen in this ECG?
Right bundle branch block
Which type of bundle branch block is seen in this ECG?
Left bundle branch block
