1

Torsade de Pointes 

(Polymorphic ventricular tachycardia)

2

Supraventricular Tachycardia 

3

Atrial Fibrillation 

4

Ventricular Tachycardia 

5

Pericarditis 

(Saddle shaped ST elevation)

6

2nd Degree Heart Block (Mobitz II) 

7

Atrial Flutter 

 

(Saw tooth baseline)

8

Sinus Ryhthm  

 

(All complexes normal and frequency is between 60 to 100 beats per minute.)

9

Sinus Bradycardia 

 

(A sinus rhythm of less than 60 beats per minute.)

10

Sinus Tachycardia 

 

(The sinus node sends out electrical signals faster than usual, speeding up the rate. A sinus rhythm of more than 100 beats per minute.)

11

Ventricular Fibrillation

12

First Degree Heart Block 

(involves affixed prolonged PR interval (>200 ms). Occurs between the SA node and the AV node (i.e. within the atrium).) 

 

13

Second Degree Heart Block (Mobitx I) 

 

(: if the PR interval slowly increases then there is a dropped QRS complex (beat). This is a mobitz type I second degree AV block (Wenckebach). Occurs in the Av node. This is the only piece of conductive tissue in the heart which exhibits the ability to conduct at different speeds.)

Second Degree Heart Block (Mobitx I) 

15

Second Degree Heart Block (Mobitx I) 

16

Second Degree Heart Block (Mobitx I) 

17

Second Degree Heart Block (Mobitx II) 

 

(if the PR interval is fixed but there dropped beats, this is mobitz type II second degree heart block (clarify that by the frequency of dropped beats e.g. 2:1, 3:1, 4:1. Occurs after the AV node in the bundle of His or Purkinje Fibres. DROPPED QRS complex) 

18

Third Degree Heart block (Complete heart block)

 

In complete heart block, there is complete absence of AV conduction – none of the supraventricular impulses are conducted to the ventricles.
