This book represents another in the long list of texts devoted to arrhythmias of the heart. The book is aimed primarily at students and practitioners; to this end, it is written clearly, succinctly, and with little equivocation. The number of visual aids is prodigious and, in the main, of high quality and purpose. The authors have successfully blended electrophysiologic events with their mechanical counterparts, and the emphasis on functional or hemodynamic consequences of arrhythmias is refreshing. In particular, I approve of the distinction between benign and malignant ventricular tachycardia. The latter occurs when the impulse originates in a fashion so as to compromise effective contraction with consequent fall in blood pressure and output. The mechanism is altered contractility here and not solely a function of rate which may actually be normal.
On the deficit side of the ledger, any text aimed at tl._ student should have a more extensive and
