Myocardial contraction is 5-fold more economical in ventricular than in atrial human tissue.

abstract：:The last decade has seen a dramatic increase in the understanding of the molecular basis of arrhythmias. Much of this new information has been driven by genetic studies that focused on rare, monogenic arrhythmia syndromes that were accompanied or followed by cellular electrophysiological or biochemical studies.
