Pulse rhythm

Pulse rhythm

Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac...

Disturbances in Heart Rhythm

Disturbances in Heart Rhythm

Arrhythmia or dysrhythmia refers to an abnormal heart rhythm caused by a defect in the heart's conduction system. It can cause the heart to beat irregularly, too quickly, or too slowly, leading to symptoms like chest pain, shortness of breath, and fainting. Factors such as stress, caffeine, alcohol, nicotine, cocaine, certain drugs, congenital defects, diseases, and electrolyte abnormalities can trigger arrhythmias.
Arrhythmias are categorized by their speed, rhythm, and origin. A slow...

Area of Science:

Cardiology
Medical Informatics
Artificial Intelligence in Medicine

Background:

Accurate prediction of paroxysmal and persistent atrial fibrillation (AF) subtypes is challenging without immediate electrocardiogram (ECG) monitoring.
Current methods lack reliable prediction of AF subtypes prior to ECG confirmation.

Purpose of the Study:

To develop a machine learning model for predicting paroxysmal and persistent AF subtypes using readily available baseline data.
To identify the key influencing factors in AF subtype prediction.

Main Methods:

Collected demographic, medication, serological, and cardiac ultrasound data (50 variables).
Utilized Spearman correlation, recursive feature elimination, and LASSO regression for variable selection.
Developed and evaluated AF prediction models using three machine learning algorithms.
Analyzed variable importance with Shapley additive explanations.

Main Results:

An optimal set of 10 variables was identified for the prediction model.
The model demonstrated strong predictive performance with an AUC of 0.870 (95% CI: 0.858-0.882).
Left atrial size (LA) and NT-proBNP were identified as the most significant predictors, except in specific subgroups.

Conclusions:

The developed model enables prediction of AF subtypes from baseline admission data.
This predictive capability supports early, individualized intervention strategies to potentially improve clinical outcomes in AF patients.
