The practical wrist pulse of the healthy person and the coronary heart disease patient were analyzed by wavelet transform (WT) and hilbert huang transform ( HHT), and the characteristic information (percentage of energy density) of the pulse signal was discussed. The simulation results show that both WT and HHT are efficient ways in analyzing and processing pulse signal, and can draw main characteristic information from pulse signal. However the basis function is preselected in WT, it doesnt need to be preselected in HHT. In HHT the intrinsic mode function (IMF) is obtained by empirical mode decomposition (EMD), it can reflect the instantaneous frequency of pulse signal, and has the actual physical meaning. The resolving power of time and frequency in WT is restricted by Heisenberg uncertainty principle, and is restricted by each other. While the resolving power of time and frequency in HHT is adaptively changed according to signal intrinsic characteristics. The HHT is more adaptive than WT in analyzing pulse signal. The HHT can offer a new idea to diagnose cardiovascular disease by wrist pulse signal.

Background: Coronary heart disease patients shall experience physical, psychological and social changes that will affect life. The psychological condition of outpatients that has been investigated include anxiety, depression and quality of life, all of these problems can be attributed to resilience.Objective: The purpose of this study was to determine the image of resilience of coronary heart disease patient following up the acute attack in outpatient ward.Methods:  The research method used quantitative descriptive using CD-RISC instrument 25. Instrument had validity value r = 0.83, P <.0001 and reliability value of Cronbach’s α 0.89. The selection of sample with consecutive sampling and got sample number 50 people for 2 weeks. Data were analyzed based on the value of each respondent categorized using tertile to see the overall resilience picture, while for the five sub-variables measured using the mean and standard deviation.Result: The results showed that almost half of respondents had 70-75 resilience. The mean value of sub-variables if sorted from the lowest to the highest is trust and reinforcement (2.71±0.58); competence and resilience (2.88±0.53); relationships with others (2.92±0.48); self-control (3.04±0.62) and spiritual influence (3.33±0.45). These results are influenced by lack of self-efficacy, optimism and family support.Conclusion: The conclusions of the research resilience of patients are in the medium category, for the lowest sub-variable value is trust and strengthening, while the highest is the spiritual influence. So, it is advisable to provide education to improve management skills post-acute attacks and increase social support in the care of patients at home.

Coronary heart patients are very strong subjects in the research of verbal interaction profiles. Because a lot of verbal interactions must be understood by patients as communicators. Simple communication theory to find this interaction has several elements, namely Communicator, Message (Message), Channel, Communicative, and Feed back. This type of research uses qualitative descriptive methods including observations in the location of the safira panjen Malang Main clinic, in-depth interviews with coronary heart patients who were included in the informant's criteria as a sample, namely Mr. Suryadi who had long been treated as a coronary heart disease patient, as the primary informant , and supporting informants namely the closest person and specialist doctor and then data analysis. The results of this study can be concluded 1.) the profile of verbal interaction of coronary heart patients in communicating has Determinism the use of verbalization generally has conditions directed to meet the desired goals of coronary heart patients (communicators) in expressing messages in the form of language, symbols, chennel in the form of senses and HP in communicating, Feed Back with communicants, this leads to healing, and verbal interactions of a coronary heart patient (communicator) experience repeated conditions with the assumption that using Indonesian or Javanese language kromo inggil, Channel, Feed back given by communicant in this is like; family environment, workplace and physician at the same time) in Communicating Coronary Jatung Patients who finally get the full understanding and comfort and discomfort to influence their health condition, 2.) Obstacles are also experienced in interacting which lead to Polarization, Evaluation of Stasis in Coronary Heart Patients, Stereotypes Between Patients with Coronary Hearts (Communicators) with their communicants.
