Effect of inspiratory and expiratory phases of normal quiet breathing, deep breathing and savitri pranayam type breathing on heart rate and mean ventricular QRS axis was investigated in young, healthy untrained subjects. Pranayam type breathing produced significant cardioacceleration and increase in QRS axis during the inspiratory phase as compared to eupnea. On the other hand, expiratory effort during pranayam type breathing did not produce any significant change in heart rate or QRS axis. The changes in heart rate and QRS axis during the inspiratory and expiratory phases of pranayam type breathing were similar to the changes observed during the corresponding phases of deep breathing.
在年轻、健康且未经训练的受试者中，研究了正常安静呼吸、深呼吸和萨维特里呼吸法类型的呼吸的吸气和呼气阶段对心率和平均心室QRS轴的影响。与平静呼吸相比，呼吸法类型的呼吸在吸气阶段会产生显著的心动加速和QRS轴增加。另一方面，呼吸法类型的呼吸过程中的呼气努力并未使心率或QRS轴产生任何显著变化。呼吸法类型的呼吸的吸气和呼气阶段中心率和QRS轴的变化与深呼吸相应阶段中观察到的变化相似。
