Preface

By reading this book, the reader can get more knowledge on some of the most common car‐ diac arrhythmias.

Electrical disturbances in the atria of the heart have been very well presented in this book by different authors. The main chapters of the book refer to such supraventricular arrhythmias.

Interested readers on this topic can value the different antiarrhythmic agents against such cardiac arrhythmias, mainly the role of "Amiodarone" in these kinds of cardiac events.

This is definitely an interesting book, and it is worthy of being read.

My congratulations to all authors who have written the different chapters covering some of the most interesting advances on this topic.

Their dedication is appreciated.
