Abstract： This article introduces Professor JI Yunxi's clinical experience in treating palpitations based on the yang-supporting theory. Professor JI believes that yang deficiency is the root cause of palpitations，which leads to the development of phlegm-dampness， blood stasis， and qi stagnation. Therefore， the differentiation and treatment of palpitations should prioritize supporting yang. The treatment often starts with warming and tonifying heart yang， strengthening the transportation and transformation of spleen yang，and replenishing kidney essence，supplemented by methods such as activating blood circulation and resolving stasis，as well as calming the spirit and stabilizing the mind. In clinical practice， his self-formulated Xinji Prescription is used as the basic prescription and modified based on symptom types，demonstrating significant therapeutic efficacy.
