At the end of the study period, it was found that the practice of pranayama had helped each and every patient, but especially those suffering from angina and ischemia. Many other research studies have verified that pranayama is extremely beneficial for the heart. The practices minimize the stress put on the cardiac system by day-to-day life. Breathing with slow, deep and long breaths gives rest to the heart. Many heart conditions can be managed through pranayama.
Nadi shodhana pranayama in particular exercises the whole cardiac system. In this practice the ratio of 1:2 maintained between inhalation and exhalation has a direct relationship with the systolic and diastolic periods of the cardiac rhythm. When the heart is damaged, the ratio between the systolic and diastolic periods often becomes 2:1, 3:1 or even 5:1; however, with regular practice of nadi shodhana, the correct rhythm can be restored. One can observe from the pulse that the heart rate speeds up with inspiration and slows down with expiration.
