In Dale Dubin flashcards, the height or depth of waves is a measurement of the voltage, while an upward deflection represents the voltage and the vertical amplitude represents a measure of voltage.
In the context of Dale Dubin flashcards, which are commonly used for studying electrocardiography (ECG) interpretation, the height or depth of waves refers to the measurement of voltage. In an ECG waveform, different waves such as the P wave, QRS complex, and T wave represent the electrical activity of the heart. The vertical distance from the baseline to the peak or trough of these waves corresponds to the voltage.
When a waveform exhibits an upward deflection, it represents a positive voltage. This means that there is an electrical potential difference in the positive direction, indicating the depolarization or activation of cardiac cells. Conversely, a downward deflection represents a negative voltage or a potential difference in the negative direction.
The amplitude of a waveform, particularly its vertical amplitude, is a measure of voltage. It represents the maximum displacement of the waveform from the baseline and reflects the strength or magnitude of the electrical signal. A larger vertical amplitude signifies a higher voltage, indicating a more pronounced electrical activity or abnormality in the heart.
