Pulse rhythm01:30

Pulse rhythm

952
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...

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

189
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...

Electrocardiogram01:29

Electrocardiogram

3.4K
An electrocardiogram (ECG or EKG) is a critical diagnostic tool that records the electrical signals produced by the heart during each heartbeat. This recording is achieved through electrodes placed strategically on the arms, legs, and chest. The electrocardiograph amplifies these signals and produces 12 distinct tracings, offering a comprehensive understanding of the heart's electrical activity.
Three major waveforms are present in a typical ECG recording: the P wave, the QRS complex, and...

Seizures: Classification

631
Epilepsy is primarily characterized by unpredictable seizures, either provoked by an identifiable factor, such as injury or illness, or unprovoked, occurring spontaneously without apparent cause.
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:

Electrophysiology of Normal Cardiac Rhythm01:19

Electrophysiology of Normal Cardiac Rhythm

7.0K
The normal cardiac rhythm is a synchronized electrical activity that facilitates the regular and coordinated contraction of the heart muscle. This process is essential for efficient blood circulation throughout the body. The fundamental elements involved in establishing and maintaining this rhythm include the unique electrical properties of cardiac muscle cells, the sinoatrial (SA) node's pacemaker function, the specialized conducting system, and the ionic mechanisms underlying each phase...

Disturbances in Heart Rhythm01:29

Disturbances in Heart Rhythm

1.3K
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...

Area of Science:

  • Cardiology
  • Biomedical Engineering
  • Artificial Intelligence

Background:

  • Electrocardiogram (ECG) signals are crucial for diagnosing heart diseases, with abnormal heartbeats like premature ventricular contractions (PVCs) indicating serious conditions.
  • Automated computer-assisted techniques are increasingly vital for reducing the diagnostic burden of identifying heart arrhythmias.
  • PVCs are a common arrhythmia originating in the heart's lower chambers, potentially leading to severe health issues.

Purpose of the Study:

  • To propose and evaluate a deep learning-based approach for accurate recognition of premature ventricular contractions (PVCs).
  • To leverage extracted ECG signal features for enhanced automatic arrhythmia detection.

Main Methods:

  • Extracted 10 heartbeat and statistical features, including morphological (RS amplitude, QR amplitude, QRS width) and statistical measures, from 20-second ECG signal segments.
  • Constructed feature vectors from the extracted ECG data.
  • Utilized a convolutional neural network (CNN) to analyze feature patterns for effective PVC classification.

Main Results:

  • The proposed pipeline demonstrated improved diagnostic performance in identifying PVCs.
  • The deep learning approach effectively classified unique patterns within the ECG features.

Conclusions:

  • The developed deep learning pipeline shows significant promise for improving the accuracy and efficiency of automatic PVC detection.
  • This method can aid in the early diagnosis of heart conditions, reducing the workload on medical professionals.
