Electrocardiographic parameters, including P wave abnormalities, prolonged QT intervals, QRS fragmentation, and ST segment changes, are associated with cardiovascular mortality.
What are the electrocardiographic predictors of cardiovascular mortality in the general population and athletes?
This review highlights key ECG parameters that can serve as accessible and inexpensive predictors of cardiovascular mortality in clinical practice.
Cardiovascular diseases are the main causes of mortality. Sudden cardiac death may also appear in athletes, due to underlying congenital or inherited cardiac abnormalities. The electrocardiogram is used in clinical practice and clinical trials, as a valid, reliable, accessible, inexpensive method. The aim of the present paper was to review electrocardiographic (ECG) signs associated with cardiovascular mortality and the mechanisms underlying those associations, providing a brief description of the main studies in this area, and consider their implication for clinical practice in the general population and athletes. The main ECG parameters associated with cardiovascular mortality in the present paper are the P wave (duration, interatrial block, and deep terminal negativity of the P wave in V1), prolonged QT and Tpeak-Tend intervals, QRS duration and fragmentation, bundle branch block, ST segment depression and elevation, T waves (inverted, T wave axes), spatial angles between QRS and T vectors, premature ventricular contractions, and ECG hypertrophy criteria.
Mozoş et al. (Thu,) conducted a review in Cardiovascular mortality. Electrocardiographic (ECG) signs was evaluated on Cardiovascular mortality. Electrocardiographic parameters, including P wave abnormalities, prolonged QT intervals, QRS fragmentation, and ST segment changes, are associated with cardiovascular mortality.
