Welcome to ep-easy.com – a project aimed at de-mystifying principles and concepts of cardiac electrophysiology. The main intended audience consists of cardiology & EP doctors in training and cardiac physiologists in training.
EP is a fascinating field – probably the most advanced of all specializations within cardiology – and most things that we do to treat rhythm disorders have fundamental technical principles which – at times can be daunting for the trainee – you bet it did for me.
There are numerous excellent textbooks that describe these in detail – but for the time -pressed trainee, reading all of them is not an option – and unfortunately most comprehensive books can be exhausting to understand – even for a simple principle.
Fortunately, majority of the common arrhythmia can be treated without a deep understanding these concepts – Unfortunately, the most hyped and fashionable disease – atrial fibrillation, does not require that much of “electrophysiolgy” – but being good in burning lines help. Given the burden of AF, basic electrophysiology is becoming a distant enigma for most trainees. The end result is the frustration in understanding and managing an arrhythmia which goes haywire from usual behavior.
My sincere goal is that readers of this project will understand and appreciate the wonderful mechanisms of cardiac arrhythmia and develop a scientific approach to managing them and become true electrophysiologists – not ablationists.
