12.6 : 脉搏节律

The pulse rhythm is the pattern of the pulsing beat within specific intervals.

A regular pulse is characterized by a standard heart rate with uniform waveforms and pulsation force and can be normal, weak, or bounding.

An irregular pulse pattern is known as dysrhythmia, which occurs due to a disturbance in cardiac muscle contraction.

The broad classification of dysrhythmias includes regularly irregular and irregularly irregular dysrhythmias.

Regularly irregular dysrhythmias have premature ectopic beats, whereas irregularly irregular ones transmit irregular electrical activity to the ventricles.

Some regularly irregular pulses are pulsus bigeminus, coupled extrasystoles, and wenckebach.

Whereas atrial fibrillation, premature ventricular contractions, ventricular extrasystoles & ectopic beats are irregularly irregular pulses.

The following are some of the methods to assess dysrhythmias.

An electrocardiogram records the heart's electrical activity, which can diagnose various problems related to the cardiovascular system.

Holter monitoring is a diagnostic test that records cardiac electrical activity for 24 hours continuously.

For extended monitoring, cardiac telemetry provides continuous monitoring of the heart's electrical activity.
