Research Hypothesis: The study hypothesizes that regular use of electronic cigarettes (ECs) in healthy young adults aged 18 to 24 could be associated with alterations in electrocardiographic (ECG) parameters, particularly those related to ventricular repolarization. The specific hypothesis is that increased duration and frequency of EC use may correlate with changes in ECG findings such as Tp-e/QT and Tp-e/QTc ratios, which are indicators of ventricular repolarization and have been linked to cardiac arrhythmia risks. Data Description: The study included 183 participants aged 18-24, who were active electronic cigarette users in the department of Atlantico during the second semester of 2023. Electrocardiographic (ECG) recordings were obtained, and data was collected across several variables (Microsoft Excel): Sociodemographic data: Age, gender, socioeconomic status. Clinical data: Presence of symptoms like dyspnea, palpitations, resting heart rate, and oxygen saturation. ECG parameters: PR interval, QRS complex, QT interval, corrected QT (QTc), Tp-e (interval between the peak and end of the T wave), Tp-e/QT, and Tp-e/QTc. Electronic cigarette usage characteristics: Duration of use (in months/years), frequency (days per week), intensity (e.g., number of inhalations per day), and nicotine concentration. Associated habits: Physical activity, alcohol, and energy drink consumption.
