True or False: A waveform is defined as movement away from the baseline in either a positive or negative direction.

The statement is accurate because a waveform is characterized by its representation of electrical activity in the heart as it deviates from a baseline on an electrocardiogram (ECG). In this context, movement away from the baseline can occur in two directions: upwards (positive deflection) and downwards (negative deflection). This dual movement is crucial for interpreting the electrical signals that correspond to various phases of the cardiac cycle.

Each movement away from the baseline provides valuable information about the heart's function, such as the depolarization and repolarization of the heart muscle. By analyzing these fluctuations, healthcare professionals can gain insights into the heart's rhythm, overall electrical activity, and potential abnormalities. Therefore, the understanding that a waveform includes both positive and negative movements is fundamental in ECG interpretation.
