On the Patterns of Cardiac Rhythm in Healthy Men, with Especial Reference to the Slow Rhythm Simulating Traube-Hering Waves of Blood Pressure

Abstract

1. The pattern of cardiac rhythm of man as observed by means of cardiotachograph, is to some extent, a characteristic to each individual.
2. By repeated and careful observations on twenty normal individuals there were recognized three main components of cardiac rhythm which characterized its pattern. That is 1) the respiratory arrhythmias, 2) the slow waves and 3) the irregular waves.
3. The features of these three components except the respiratory arrhythmias were described and discussed.
