[Changes of the first electrocardiographic derivative in patients with ischemic heart disease]
Insights
Analyzing the first electrocardiographic derivative aids in early ischemic heart disease (IHD) detection. This method reveals significant changes in ventricular repolarization during myocardial ischemia, improving diagnosis.
Area of Science:
- Cardiology
- Medical Diagnostics
- Physiology
Background:
- Early detection of ischemic heart disease (IHD) is crucial in cardiology.
- Identifying pathological myocardial changes requires continuous research.
- Electrocardiography (ECG) is a key diagnostic tool, with advanced analysis offering deeper insights.
Purpose of the Study:
- To evaluate the utility of the first electrocardiographic derivative in diagnosing myocardial ischemic changes.
- To explore novel methods for early recognition of IHD.
Main Methods:
- Analysis of the first electrocardiographic derivative in patients with proven IHD.
- Comparison with a control group of subjects without cardiovascular diseases.
- Assessment of temporal and velocity parameters of ventricular repolarization.
Main Results:
- Significant alterations in temporal and velocity parameters of the first electrocardiographic derivative were observed during myocardial ischemia.
- Intervals were notably lengthened, and velocity parameters decreased.
- These changes were distinct in patients with IHD compared to the control group.
Conclusions:
- The analysis of the first electrocardiographic derivative shows promise for the differential diagnosis of myocardial ischemic changes.
- This advanced ECG analysis can provide valuable information for identifying IHD.
- Further research may establish this method as a standard diagnostic approach.
Abstract:
Timely recognition of ischemic heart disease (IHD) is one of the main tasks of cardiology. As a result the search for ways of early recognition of pathologic changes of the myocardium is continuing. Analysis of the first electrocardiographic derivative allows making more detailed assessment of repolarization processes in ventricles. Aim of this study was to assess possibility of the use of analysis of the first electrocardiographic derivative in diagnosis of ischemic changes of myocardium. We examined 61 patients (mean age 63.9+/-9.4 years) with proven ischemic heart disease (IHD). Control group included 92 subjects (mean age 33.1+/-15.4 years) without cardiovascular diseases. Basing on obtained results a conclusion was made that temporal and velocity parameters of the first electrocardiographic derivative changed dramatically during myocardial ischemia: all intervals became lengthened and velocity parameters decreased. Thus analysis of the first electrocardiographic derivative can be useful in differential diagnosis of myocardial ischemic changes.

Cardiac Action Potential
The cardiac action potential process involves a series of phases characterized by the movement of ions across the cardiac cell membranes, leading to the depolarization and repolarization of the cardiac myocytes.

Correlation between ECG and Cardiac Cycle
A cardiac action potential originates in the SA node and spreads throughout the atria and the AV node in approximately 0.03 seconds. This results in the P wave in an ECG and triggers atrial contraction. The action potential is then briefly slowed at the AV node, allowing the atria to contract and fill the ventricles with blood before...
