Mathematical and Preclinical Investigation of Respiratory Sinus Arrhythmia Effects on Cardiac Output [PDF]

arXiv, 2020
Respiratory sinus arrhythmia (RSA) is heart rate variability in synchrony with respiration although its functional significance not clear. The loss of sinus arrhythmia may indicate underlying heart failure or disease; therefore, there would be a great advantage of knowing how it works and affects the cardio-respiratory system, especially by providing a

A lightweight hybrid CNN-LSTM model for ECG-based arrhythmia detection [PDF]

arXiv, 2022
Electrocardiogram (ECG) is the most frequent and routine diagnostic tool used for monitoring heart electrical signals and evaluating its functionality. The human heart can suffer from a variety of diseases, including cardiac arrhythmias. Arrhythmia is an irregular heart rhythm that in severe cases can lead to heart stroke and can be diagnosed via ECG ...

Sudden Cardiac Death and Arrhythmias.

Arrhythmia & Electrophysiology Review, 2018
Sudden cardiac death (SCD) and arrhythmia represent a major worldwide public health problem, accounting for 15-20 % of all deaths. Early resuscitation and defibrillation remains the key to survival, yet its implementation and the access to public ...

Genomics and Cardiac Arrhythmias [PDF]

Journal of the American College of Cardiology, 2006
Sudden cardiac death in patients younger than 35 years of age is primarily due to genetic causes. Familial hypertrophic cardiomyopathy accounting for 30% to 40% is associated with structural heart disease while the Brugada syndrome and the long QT syndrome (LQTS) are associated with normal cardiac function.

Day‐to‐day fasting plasma glucose variability on the short‐term prognosis of ST‐segment elevation myocardial infarction: A retrospective cohort study

Clinical Cardiology, Volume 45, Issue 12, Page 1246-1254, December 2022., 2022
Abstract Background and Hypothesis Glycemic variability in one fact that explain the differences in cardiovascular outcomes. The short‐term fasting plasma glucose (FPG) variability may have an on major adverse cardiovascular events (MACE) in type 2 diabetes mellitus (T2DM) patients with ST‐segment elevation myocardial infarction (STEMI).

A K_ATP channel opener inhibited myocardial reperfusion action potential shortening and arrhythmias [PDF]

, 2001
Low concentrations of certain K_ATP channel openers have been reported to exert a moderate inhibitory effect on arrhythmias during post-ischaemic early myocardial reperfusion, but the accompanying effects on the time course of ...

Ventricular Arrhythmias in Cardiac Sarcoidosis

Circulation, 2018
The diagnosis of cardiac sarcoidosis (CS), especially in cases where there is limited or no extracardiac involvement, is challenging. Patients with CS are at increased risk of ventricular arrhythmias and sudden cardiac death.
