Dr. John Hui,works with Dr. Clifford Birtwell, the inventor of the concept of counter-pulsation.
He is the last Fellow of Dr. Birtwell.

Dr. Zheng and his colleagues at Sun Yat Sen University in China report their studies of a newly
designed sequenced pulsation system using four sets of compression bladders on patient’s calves, thighs, buttocks and arms. They name these devices MC1 and MC2.
To differentiate this new system from the other ECP systems, Dr. Hui and his colleagues at Vasomedical call this technology Enhanced External Counterpulsation or EECP using the MC2
The FDA then approves EECP, and the use of the MC1 device for treatment of cardio-genic shock and myocardial infraction. (heart attack)
