    Insights

    Electrocardiograms (ECGs) in premature infants at 1 year show right ventricular hypertrophy in those with lung disease. Neonatal patent ductus arteriosus did not impact these ECG findings.

    Area of Science:

    • Pediatrics
    • Cardiology
    • Neonatology

    Background:

    • Premature infants often experience respiratory issues like bronchopulmonary dysplasia.
    • Long-term cardiac effects of prematurity and associated lung disease require further investigation.
    • Electrocardiography (ECG) is a non-invasive tool for assessing cardiac health.

    Purpose of the Study:

    • To evaluate the 1-year cardiac status of premature infants using ECG.
    • To determine the correlation between bronchopulmonary dysplasia and ECG findings in this cohort.
    • To assess the influence of neonatal patent ductus arteriosus on long-term cardiac outcomes.

    Main Methods:

    • ECGs were collected from 461 premature infants at 1 year of age.
    • Infants were categorized based on the presence and persistence of bronchopulmonary dysplasia.
    • Data were compared to published norms for healthy infants and analyzed for specific cardiac abnormalities.

    Main Results:

    • ECGs of infants without bronchopulmonary dysplasia were similar to healthy norms.
    • A high prevalence of right ventricular hypertrophy indicators was observed in infants with a history or persistence of lung disease.
    • Neonatal patent ductus arteriosus did not significantly affect 1-year ECG findings.

    Conclusions:

    • ECG can reveal cardiac changes associated with chronic lung disease in premature infants.
    • The findings suggest ECG is a valuable tool for monitoring residual lung disease sequelae.
    • Further research can refine ECG's role in the long-term follow-up of high-risk infant populations.

    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 the T...
    Correlation between ECG and Cardiac Cycle01:25

    Correlation between ECG and Cardiac Cycle

    The electrical signals recorded on an electrocardiogram (ECG) occur before the mechanical processes of contraction and relaxation during the 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...
    Cardiac Action Potential01:30

    Cardiac Action Potential

    Cardiac action potentials are essential for proper heart function, enabling the rhythmic contractions needed for adequate blood circulation. Nodal cells and Purkinje fibers, specialized for electrical conduction, generate these action potentials.
    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.

    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 to...

    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. When...

    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...
