FIRST YEAR PHYSIOLOGY: CVS PART 2 (STUDY OF ECG)

 STUDY OF ECG :

IMPORTANT QUESTIONS FOR SEQs :

Chapter # 11:

*ECG graph with different waves
* characteristics of waves in ECG record
*How the current flows around the heart?
* ECG leads
* Einthoven's Triangle
* Different types of ECG leads
*Different intervals and segments in ECG record (PR,QT interval and ST segment etc)

Chapter # 12

* Hexagonal reference system ( diagram)
*axis of bipolar and unipolar leads
*vectocardiogram
*Right and left axis deviation of heart
* current of injury
*Right and left bundle branch block
*Abnormalities of QRS complex and T wave

Chapter # 13

* Tachycardia and Bradycardia
*carotid sinus syndrome
*Atrioventricular heart blocks( 1,2,3 degree)
*what is stokes Adam syndrome
* premature contractions
* compensatory pause
*paroxysmal tachycardia
*circus movement in ventricular fibrillation
* Difference b/w atrial fibrillation and ventricular fibrillation
*cardiac arrest

Note:
All ECG graphs of chapter 13 are very important especially heart blocks, premature contractions, atrial and ventricular fibrillation.
