Prevent heart attacks using advanced breath control

Breathing and the heart

Our breathing pattern has profound effects on the heart. In fact, about a century ago western doctors developed and studied the science which was called “cardiorespiratory physiology”. Why? Because of the close connections between cardiovascular and respiratory systems. Yale University Professor Yandell Henderson (1873-1944) was the father of cardiorespiratory physiology. He wrote first physiological textbooks.

A century ago, in 1908, he published some of his results in the American Journal of Physiology. The title of his study was “Carbon dioxide as a factor in the regulation of the heart rate”. Professor Henderson found that when breathing gets bigger and deeper, CO2 level in the blood drops below the norm, arteries and arterioles constrict, and it is more difficult for the heart to pump the blood. Moreover, forceful hyperventilation done by suction and exhaust pumps killed all his dogs in less than 30 minutes due to … cardiac arrest! He wrote, “… we were enabled to regulate the heart to any desired rate from 40 or fewer up to 200 or more beats per minute. The method was very simple. It depended on the manipulation of the hand bellows with which artificial respiration was administered… As the pulmonary ventilation increased or diminished the heart rate was correspondingly accelerated or retarded” (p.127, Henderson, 1908). Obviously, heavy breathing caused very high heart rate, spasms of coronary arteries, and death of his animals.

During more recent times it was also found that even slight over-breathing reduces heart blood supply (since CO2 is a vasodilator) and oxygenation (due to the suppressed Bohr Effect), creates abnormal excitability of pace makers, and suppresses perfusion of the heart muscle. Hence, over-breathing creates several different abnormalities in the cardiovascular system.
