Short Term Hemodynamic Effects of Controlled Slow Breathing With Biofeedback in Patients With Heart Failure

Summary

Heart failure is associated with faster breathing, which has a negative impact on the functioning of the heart. This leads to fatigue, shortness of breath, and exercise intolerance. It has been shown that when slow breathing technique was taught to patients with heart failure, they had a reduction in their sensation of shortness of breath and an improvement in their exercise performance.

The study will compare the short-term effects of controlled slow breathing with biofeedback in normal healthy subjects, acute heart failure, and chronic stable heart failure. The purpose is to see if there is any change in the objective measurements of heart function while breathing at normal rates compared to a controlled slower rate.

Interventions

BEHAVIORAL

Slow breathing

The subjects will be given instructions in slow breathing at a rate of 6 to 10 breaths per minute and asked to practice it for some time. Hemodynamic measurements would be repeated before, during and after the trial of slow breathing. A Noninvasive Cardiac Output Monitor will be used. It uses a technology called impedance to measure cardiac output and other hemodynamic parameters by the passage of electric currents through the thorax. This device uses four electrode stickers applied to the thorax and the neck.
