A Time-Frequency Domain Approach of Heart Rate Estimation From Photoplethysmographic (PPG) Signal [PDF]
, 2017 Objective- Heart rate monitoring using wrist type Photoplethysmographic (PPG) signals is getting popularity because of construction simplicity and low cost of wearable devices. The task becomes very difficult due to the presence of various motion artifacts.

Heart Diseases Prediction Using Block-chain and Machine Learning [PDF]
arXiv, 2023 Most people around the globe are dying due to heart disease. The main reason behind the rapid increase in the death rate due to heart disease is that there is no infrastructure developed for the healthcare department that can provide a secure way of data storage and transmission.

Study of conduction, block and reflection at the excitable tissues boundary in terms of the interval model of action potential [PDF]
arXiv, 2021 Some mechanisms of cardiac arrhythmias can be presented as a composition of elementary acts of block and reflection on the contacts of homogeneous areas of the conducting tissue. For study this phenomena we use an axiomatic one-dimensional model of interaction of cells of excitable tissue.

Circulation, 2008 A 56-year-old man of Turkish descent presented with severe bradycardia (37 bpm) and hypotension (65/35 mm Hg) in the emergency room. A liver transplantation had been performed 8 months before because of cirrhosis due to chronic hepatitis B. The patient was on a permanent regimen of tacrolimus, mycophenolate mofetil, lamivudine, and adefovir dipivoxil ...

Vision Transformers increase efficiency of 3D cardiac CT multi-label segmentation [PDF]
arXiv, 2023 Accurate segmentation of the heart is essential for personalized blood flow simulations and surgical intervention planning. Segmentations need to be accurate in every spatial dimension, which is not ensured by segmenting data slice by slice. Two cardiac computed tomography (CT) datasets consisting of 760 volumes across the whole cardiac cycle from 39 ...

Characteristics of the Kelch domain containing (KLHDC) subfamily and relationships with diseases
FEBS Letters, EarlyView.The Kelch protein superfamily includes 63 members, with the KLHDC subfamily having 10 proteins. While their functions are not fully understood, recent advances in KLHDC2's structure and role in protein degradation have highlighted its potential for drug development, especially in PROTAC therapies.
