Holter system electrocardiographic studies on 617 cases

T Tanabe, H Furuya, N Kanemoto

    The Tokai Journal of Experimental and Clinical Medicine
    |January 1, 1980
    PubMed
    Summary

    Holter electrocardiograms are effective for diagnosing arrhythmias like ventricular premature contractions and assessing prognosis. However, their utility for diagnosing ischemic heart disease, excluding variant angina, remains limited.

    Area of Science:

    • Cardiology
    • Diagnostic Medicine
    • Cardiac Electrophysiology

    Background:

    • Arrhythmias are common cardiac conditions requiring accurate diagnosis.
    • Holter monitoring is a standard tool for ambulatory electrocardiogram recording.
    • Evaluating the diagnostic and prognostic capabilities of Holter monitoring is crucial.

    Purpose of the Study:

    • To assess the diagnostic utility of Holter electrocardiograms (EKGs) for various arrhythmias.
    • To determine the effectiveness of Holter EKGs in identifying ischemic heart disease.
    • To evaluate the prognostic value of Holter monitoring in cardiology patients.

    Main Methods:

    • Retrospective analysis of Holter EKGs from 617 patients.
    • Categorization and quantification of different types of arrhythmias detected.

  • Correlation of EKG findings with diagnoses, including ischemic heart disease and variant angina.

    • Main Results:

    • Ventricular premature contraction (VPC) was the most frequent arrhythmia (69% of 423 cases with arrhythmia).
    • Severe arrhythmias including ventricular tachycardia (VT) and ventricular fibrillation (VF) were identified.
    • Significant ST segment changes suggestive of ischemia were rare (2.9%), with variant angina being a notable exception.

    Conclusions:

    • Holter EKGs are highly valuable for diagnosing a wide spectrum of arrhythmias.
    • Holter monitoring can aid in prognosis assessment for certain cardiac conditions.
    • The diagnosis of ischemic heart disease using Holter EKGs is limited, except for variant angina pectoris.
