Cardiac Arrhythmia In Anaesthesia

Abstract

The essay deals first with the anatomy of the conductive system of the hea,

/.JI which is one of the factors that may cause arrhythmia.

The study then deals with the electro-physiological changes occurring in cells df

. myocardium during passage of impulses. .

Then generally we deal with the factors which lead to arrhythmia and tJe mechanism of arrhythmogenesis of each factor . These factors are either:

- Disorder of impulse formation.

- Disorder of impulse conduction.

• . Then we deal with antiarrhythmic drugs , their classication , mechanism of action, dosage and side effects of each . . / fl Then we deal with causes of cardiac arrhythmia in the peri-operative period ahd these are classified into: -Group (A) Cardiac diseases (as systemic hypertension).

-Group (B) Other system diseases which may be

. Autonomic imbalance.

. Temperature imbalance.

. Drugs ( including anaesthetic agents)

Then the study deals with diagnosis of each type of arrhythmia , its ECG

manifestations and the treatment of each type. . . /

Then the study deals with the diagnosis and treatment of cardiac arrest rhytm , which are either : -Shockable (ventricular tachycardia and ventricular fibrillation) Non-shockable (Asystole and pulseless electrical activity)
