A 26yrs old lady who has complained of palpitations in past, is admitted
in ER with palpitations. HER ECG shows:
• Narrow complex tachycardia
• Rate about 200/min
• NO P waves
• Normal axis
• Regular QRS complexes
• Normal ST segments & T waves
 Diagnosis:
Supraventricular tachycardia (SVT)
Narrow QRS complex
Rate about 200/min
No P waves
No P waves
A 55yr old man presented with h/o chest pain at rest for 6 Hrs. There are
no abnormal physical findings. His ECG tracing shows:
• Sinus rhythm
• Normal axis
• Normal QRS complexes
• ST segment depressions, Horizontal in V3-V4
• ST segment depressions, Downward sloping in lead 1, aVL, V5-V6
 Diagnosis:
Anterolateral Ischemia(unstable angina)
ST segment depression, Horizontal
ST segment depression,
downward sloping
These 3 rhythm strips (all lead II) came from the ECGs of three different
patients. They were all in their eighties & C/O breathlessness. What
diagnosis would you consider?
A. No P waves
Irregular baselines
QRS complexes are broad, regular & slow
 Diagnosis:
Atrial fibrillation with complete block
B. Constant PR interval
2:1 conduction defect
Diagnosis:
Sinus rhythm with 2nd
degree block
C. No correlation between P waves &
QRS complexes
 Diagnosis:
Complete (3rd
degree)
heart block
a. No P waves Broad, regular, slow QRS
b.
Constant PR interval 2:1 conduction defect
No correlation b/w P waves & QRS complex
c.
This ECG was recorded from a 60 yrs old man being treated as an out patient for
severe CCF. What might be diagnosis of underlying heart conduction?
• Atrial fibrillation
• Ventricular rate of 75-200/min
• Normal axis
• Normal QRS complexes
• Downward sloping ST segment depression
esp, V5-V6
 Diagnosis:
AF with uncontrolled Ventricular rate &
digoxin effect (ST segmrnt depressions)
No P waves. Irregular HR.
(AF)
ST depression
A 15yr old boy was referred to the outpatient for heart murmur. He had
no symptoms. What does this ECG shows?
• Sinus rhythm

• Broad QRS complexes
• RSR pattern in lead I
• Wide & slurred S waves in V5
• Normal ST segments & T waves
 Diagnosis:
Right bundle branch block (RBBB)
Broad QRS complex
RSR pattern
Wide & slurred S waves
This ECG was recorded from a 25yr old pregnant women. She
complaints of an irregular heart beat. Auscultation revealed a soft systolic
murmur but her heart was otherwise normal
• Sinus rhythm
• Normal axis
• Normal QRS complexes & T waves
• Ventricular extra systoles
 Diagnosis:
Sinus rhythm with ventricular extra systoles
Ventricular Extra systole

This ECG was recorded from 60yr old women with rheumatic heart
disease. She had been in heart failure but this had been treated & she was
no longer breathless. What does this ECG shows?
• AF with ventricular rate of 60-65/min
• Normal axis
• Normal QRS complexes
• Prominent U waves in V2 (Suggest Hypokalemia)
