Effect of tachycardia heart failure on the restitution of left ventricular function in closed-chest dogs.

abstract：BACKGROUND:The rate of coronary heart disease (CHD) mortality in eastern Finland has been the highest in the world. The official mortality statistics suggest, however, that is has declined by 60% during the past 20 years. The aim of the present study was to examine the contributions of incidence, recurrence, and case f...
