Area of Science:

  • Biomedical Engineering
  • Cardiology
  • Digital Health

Background:

  • Cardiovascular diseases are a leading cause of death globally and a significant concern in Honduras.
  • Specific cardiovascular events like stroke, heart failure, and myocardial infarction frequently lead to emergency room visits.

Purpose of the Study:

  • To design and manufacture a low-cost, three-lead electrocardiograph (ECG) device for primary care applications.
  • To evaluate the performance of this device, named Handy EKG, using machine learning and Bluetooth connectivity.

Main Methods:

  • A novel three-lead ECG device (Handy EKG) was developed for primary care.
  • Bluetooth connectivity and machine learning algorithms support the device's functionality.
  • Readings from the Handy EKG were compared against a conventional 12-lead ECG in volunteer participants.

Main Results:

  • The Handy EKG successfully provided readings comparable to lead one of a 12-lead ECG.
  • A high degree of similarity (96%) in wave morphology, amplitude, and duration was observed between the devices.
  • The device demonstrated potential for continuous monitoring and mobile connectivity in various healthcare settings.

Conclusions:

  • The developed Handy EKG platform is safe and operates with good quality.
  • The device provides ECG results equivalent to conventional methods in most cases, particularly for single-lead monitoring.
  • Its portability and connectivity make it suitable for primary care and intrahospital use.

Electrocardiogram

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...

Pulse rhythm01:30

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...

Electrocardiogram Fundamentals

Introduction
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.
Parts of an ECG
An ECG utilizes electrodes on the skin...

ECG Interpretation of Rhythms

An electrocardiogram (ECG)graphically represents the heart's electrical activity on ECG paper or a monitor.
Components of the Electrocardiogram
The primary components of a normal ECG waveform in Normal sinus rhythm(NSR) include the P wave, PR interval, QRS complex, ST segment, T wave, and occasionally a U wave.
ECG waveforms are divided by vertical and horizontal lines at standard intervals.
The horizontal axis measures time and rate, and the vertical axis measures amplitude or voltage....

Equipments Used To Measure Blood Pressure

Direct Method
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...
