The T Wave is a component of the electrocardiogram (ECG or EKG) that represents the repolarization of the heart's ventricles. It follows the QRS complex, which indicates ventricular depolarization. The T Wave is crucial for understanding the heart's electrical activity and can provide insights into various cardiac conditions. In a normal ECG, the T Wave is typically asymmetrical and upright in most leads. Abnormalities in the T Wave, such as inversion or flattening, can signal issues like ischemia, hypertrophy, or electrolyte imbalances. Monitoring the T Wave helps healthcare professionals assess heart health and diagnose potential problems.
