Summary
Continuous 24-hour electrocardiography (Holter monitoring) is feasible for workers in physically demanding jobs. Ventricular extrasystoles were more prevalent in those with heart disease, while sinus node dysfunction appeared in those without.
Area of Science:
- Cardiology
- Occupational Health
- Diagnostic Monitoring
Context:
- Assessing cardiac function in physically active individuals is crucial for occupational health.
- The Holter method provides continuous electrocardiographic data over 24 hours.
- Understanding cardiac event prevalence in relation to physical exertion and underlying conditions is vital.
Purpose:
- To evaluate the feasibility and findings of 24-hour Holter monitoring in workers with physical occupations.
- To compare the occurrence of arrhythmias and heart rate patterns between workers with and without known cardiac disease.
- To investigate the relationship between physical activity intensity and heart rate trends during work hours.
Summary:
- Continuous 24-hour Holter monitoring was conducted on 64 workers, divided into groups with and without known cardiac disease.
- Results indicated Holter monitoring is viable even in demanding physical conditions, with heart rate trends correlating with activity intensity.
- Atrial arrhythmias were similarly frequent in both groups, but ventricular extrasystoles were significantly more common in the group with heart disease, particularly coronary patients.
Impact:
- This study demonstrates the utility of Holter monitoring in occupational cardiology, even under challenging physical conditions.
- Findings highlight differences in arrhythmia prevalence (ventricular extrasystoles) between healthy workers and those with cardiac conditions.
- The study underscores the need for established normal values for Holter monitoring interpretation in physically active populations.
