Insights
Cardiac arrhythmias were detected in 39.2 per thousand individuals in a Thai population survey. Atrial fibrillation and ventricular premature beats were common findings, highlighting the prevalence of these heart rhythm disorders.
Area of Science:
- Cardiology
- Public Health
- Epidemiology
Background:
- Cardiac arrhythmias are common cardiovascular conditions.
- Understanding the prevalence of arrhythmias in diverse populations is crucial for public health strategies.
- The First National Health Examination Survey of Thailand provides a valuable dataset for epidemiological research.
Purpose of the Study:
- To determine the prevalence of cardiac arrhythmias in an adult Thai population.
- To identify the prevalence rates of specific arrhythmias, including atrial fibrillation and ventricular premature beats.
- To analyze the distribution of various electrocardiographic abnormalities in the studied population.
Main Methods:
- A resting 12-lead electrocardiogram (ECG) was performed on 3,822 men and 4,969 women aged 30 years and over.
- Participants were selected from the First National Health Examination Survey of Thailand.
- Data analysis focused on identifying and quantifying different types of cardiac arrhythmias and ECG abnormalities.
Main Results:
- A total of 362 subjects (age-adjusted rate: 39.2 per thousand) exhibited cardiac arrhythmias.
- The prevalence of atrial fibrillation was 3.6 per thousand, with equal rates in males and females.
- Ventricular premature beats occurred at a rate of 12.1 per thousand (males 7.3, females 15.6). Other arrhythmias like atrial premature beats (4.0/thousand) and right bundle branch blocks (7.0/thousand) were also reported.
Conclusions:
- Cardiac arrhythmias, particularly atrial fibrillation and ventricular premature beats, are prevalent in the adult Thai population.
- The study provides essential epidemiological data on cardiac arrhythmias in Thailand.
- Further research may be warranted to explore risk factors and clinical implications of these findings.
Abstract:
The resting 12 leads electrocardiogram was recorded in 3,822 men and 4,969 women (aged 30 years or over), who participated in the First National Health Examination Survey of Thailand and the data was used to determine the prevalence of cardiac arrhythmias. In this apparently normal population 362 subjects (the standard age adjusted rate was 39.2 per thousand) had cardiac arrhythmia. The prevalence rate of atrial fibrillation was 3.6 per thousand (males 3.6, females 3.6) and ventricular premature beat was 12.1 per thousand (males 7.3, females 15.6). For atrial premature beat, complete and incomplete right bundle branch blocks, sinus arrhythmia, first degree atrioventricular block and delta wave, the prevalence rates were 4.0, 7.0, 4.6, 2.7, 2.4 and 1.3 per thousand respectively. Complete and incomplete left branch blocks, left anterior hemiblock, second degree antrioventricular block and short PR interval were rare in this survey.
