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 heart...

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 muscle...

ECG Interpretation of Arrhythmias II: Atrial, Junctional and Ventricular Arrhythmias

ECG Interpretation of Arrhythmias II: Atrial, Junctional and Ventricular Arrhythmias

Arrhythmia is a condition characterized by an irregular heart rhythm, with ECG changes that differ based on its origin and nature. The types of arrhythmias discussed below include atrial, junctional, and ventricular arrhythmias.Atrial ArrhythmiasPremature Atrial Complexes (PACs): PACs are early atrial beats caused by stress, caffeine, alcohol, electrolyte imbalances, hypoxia, hyperthyroidism, or certain medications (e.g., bronchodilators and decongestants). The ECG shows early P waves with an...

Dysrhythmias IV: Characteristics of Bradyarrhythmias

Dysrhythmias IV: Characteristics of Bradyarrhythmias

Bradyarrhythmias are cardiac rhythm disorders characterized by a slower-than-normal heart rate, typically defined as fewer than 60 beats per minute. Some of which are discussed here:Sinus BradycardiaSinus bradycardia presents a heart rate lower than 60 beats per minute, with a regular rhythm originating from the SA node. The ECG typically shows normal P waves preceding each QRS complex, a normal PR interval (0.12 to 0.20 seconds), and a normal QRS duration (0.06 to 0.10 seconds).First-Degree AV...

Assessment of apical radial pulse

Assessment of apical radial pulse

Apical-Radial (A-R) Pulse Assessment
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

Dysrhythmias VI: Management of Dysrhythmias

Dysrhythmias VI: Management of Dysrhythmias

Dysrhythmia management involves a multifaceted approach, incorporating pharmacological treatments, medical procedures, surgical interventions, lifestyle modifications, and patient education.Pharmacological ManagementAntiarrhythmic Drugs:Class I (Sodium Channel Blockers): This class includes quinidine and procainamide, which reduce the speed of impulse conduction in the heart, stabilize the cardiac membrane, and control arrhythmias. Quinidine and procainamide are Class IA agents that prolong the...

Area of Science:

Cardiology

Artificial Intelligence

Background:

Surface Electrocardiogram (ECG) is a primary noninvasive tool for diagnosing heart conditions.
Ectopic beats, common in both healthy individuals and patients, introduce significant errors in ECG analysis.
Accurate ECG interpretation requires effective methods for ectopic beat cancellation.

Purpose of the Study:

To present a novel method for electrocardiogram ectopic beat cancellation using Radial Basis Function Neural Networks (RBFNN).
To develop a customizable ECG beat classifier through a trainable neural network ensemble for improved ECG processing.
To enhance individualized healthcare by improving the accuracy of ECG analysis.

Main Methods:

Utilized the MIT-BIH arrhythmia database to obtain six types of heartbeats: Normal Beats (NB), Premature Ventricular Contractions (PVC), Left Bundle Branch Blocks (LBBB), Right Bundle Branch Blocks (RBBB), Paced Beats (PB), and Ectopic Beats (EB).
Extracted four morphological features from each heartbeat after preprocessing.
Applied a Radial Basis Function Neural Network (RBFNN) based ensemble approach for beat classification and ectopic beat cancellation.

Main Results:

The RBFNN-based method achieved an average ectopic beat reduction (EBR) of 7.23 ± 2.18.
Traditional methods achieved a best-case EBR of 4.05 ± 2.13.
The RBFNN method demonstrated highly accurate ectopic beat reduction with minimal distortion of the QRST complex.

Conclusions:

Radial Basis Function Neural Networks offer a superior approach for ectopic beat cancellation in ECG signals.
The proposed method significantly enhances the accuracy of ECG analysis by reducing ectopic beats.
This technique holds promise for improving diagnostic precision and enabling more personalized cardiac healthcare.
