procedure used to record an arterial pilse waveform using a finger pulse transducer

characteristics of a typical arterial pulse waveform

measuring pulse amplitude

measuring pulse duration

measuring cardiac cycle duration

measuring heart rate

relationship between pulse amplitude, pulse duration, cardiac cycle duration, and heart rate from a recorded arterial pulse waveform (and underlying cardiac activity)

electromyography

how electromyogram (EMG) is recorded

root mean square (RMS)

how RMS compares to raw EMG signal

why EMG activity provides an accurate measure of contractile activity

the role of motor unit recruitment in force development by a whole muscle

conduction velocity (CV)

how CV is determined for the median nerve

full sequence of events that occur during a single cardiac cycle

electrocardiography

how a recorded ECG corresponds to the cardiac cycle

PR interval

explain the physiological process responsible for the delay between the P wave and QRS complex

describe the temporal relationship between the first and second heart sounds and a typical ECG waveform (and the physiological processes responsible)

describe the temporal relationship between an arterial finger pulse and a typical ECG waveform (and the physiological processes responsible)

systolic blood pressure
