(BQ) Part 1 book "Electrocardiography of arrhythmias - A comprehensive review" presents the following contents: Important concepts, sinus node dysfunction, atrioventricular conduction abnormalities, junctional rhythm, atrioventricular nodal reentrant tachycardia, atrioventricular reentrant tachycardias.
The past thirty years have witnessed the birth, growth, and evolution of clinical electrophysiology from a field whose initial goals were the understanding of arrhythmia
mechanisms to one of significant therapeutic impact. The development and refinement of implantable devices and catheter ablation have made non-pharmacologic
therapy a treatment of choice for most arrhythmias encountered in clinical practice.
The historical route to present-day patch clamping started with the
scientific recognition that electrical phenomena are part of animal physiology.
This bioelectricity was demonstrated in the nineteenth century in
frogs, where muscle movements could be evoked by applying electrical
stimuli to the animal. The recording of inherent electrical activity can be
charted by the development of increasingly sophisticated electrodes.
To my mind electrocardiogram interpretation is all about pattern recognition. This collection of 18 articles covers all the important
patterns encountered in emergency medicine. Whether you are a novice or an experienced clinician, I hope that you find this book
enjoyable and clinically relevant.
Unproven but of potential benefit.
Many experts favor verapamil as the first-line preventive treatment for patients with chronic cluster headache or prolonged bouts. While verapamil compares favorably with lithium in practice, some patients require verapamil doses far in excess of those administered for cardiac disorders. The initial dose range is 40–80 mg twice daily; effective doses may be as high as 960 mg/d. Side effects such as constipation and leg swelling can be problematic. Of paramount concern, however, is the cardiovascular safety of verapamil, particularly at high doses.
