A flat section of line indicates no muscular activity in the heart at that particular instant; a constantly flat line indicates heart failure.

T waves on an ECG represent the repolarization of the ventricles of the heart, indicating the relaxation phase of the heart's electrical activity.
T waves in an electrocardiogram (ECG) represent the repolarization of the ventricles in the heart, indicating the recovery phase after contraction.
Objects that could represent a line include a straight ruler, a piece of string pulled taut, or a laser beam projected in a straight path. Additionally, a pencil drawn across paper creates a line, while a straight edge or a line of people standing in a row can visually represent a line. Each of these objects embodies the geometric concept of a line by demonstrating straightness and direction.
Yes, straight line AB is the same as straight line BA. Both represent the same geometric line segment connecting points A and B, regardless of the order of the points. The direction does not change the line itself; thus, AB and BA are equivalent.

An isoelectric line on the electrocardiograph is the base line on an electrocardiogram.
ECG waves represent the electrical activity of the heart, showing how it beats and functions. They can help diagnose heart conditions and monitor cardiac health.
Bar graphs and line graphs do not. Straight line, parabolic, and hyperbolic graphs are graphs of an equation.
