arrhythmia

Arrhythmia is a change in heart rhythm or rate caused by abnormalities in the origin or conduction of cardiac impulses, and is one of the most common cardiovascular manifestations in clinical practice. The clinical symptoms of arrhythmia patients vary in severity; mild cases may have no discomfort and are occasionally discovered during physical examination, while severe cases can be life-threatening. Heart rhythm is the rhythm of the heartbeat. In normal people, the heartbeat is regular, like a pendulum clock going "tick tock," "tick tock," beating very steadily according to a certain rhythm. If the rhythm of the heartbeat loses its regularity, it is called arrhythmia. Because people are accustomed to the orderly beating of the heart, they generally do not feel the heartbeat. However, once the heartbeat loses its original rhythm, discomfort is felt. Some feel "a sudden pause in the heart, like a falling sensation as if riding an elevator," some feel a sudden violent impact on the chest, and others feel as if "the heart is about to jump into the throat." More commonly, people feel chest tightness and palpitations. These are all manifestations of arrhythmia, but different people have different sensations because there are many different types of arrhythmias. Different types of arrhythmias require different treatment methods.
