What measurement technique is typically used for monitoring R wave amplitudes?

The measurement technique typically used for monitoring R wave amplitudes is the electrocardiogram (ECG). The R wave is a key component of the QRS complex seen in an ECG trace, which represents ventricular depolarization during the cardiac cycle. ECGs are specifically designed to capture and display these electrical activities of the heart, allowing healthcare professionals to assess the heart's rhythm and overall health.

ECGs provide real-time data on the amplitude, morphology, and timing of the R wave, which can indicate various cardiac conditions or the effectiveness of treatments. Therefore, using an ECG to monitor R wave amplitudes is critical for managing heart rhythm disorders and ensuring proper pacing function in devices used in cardiac rhythm management.
