As a medical professional with expertise in cardiology, I can explain the term "sinus rhythm." The term "sinus" in the context of the heart refers to the sinoatrial (SA) node, which is a group of cells located in the upper part of the right atrium of the heart. This node is often referred to as the heart's natural pacemaker.
The sinus rhythm is the regular heartbeat pattern that originates from the SA node. It is considered the normal, healthy rhythm of the heart. The term "rhythm" in this context refers to the timing and regularity of the heartbeats. When the heart beats in a regular pattern, it is said to be in sinus rhythm.
The sinus node is responsible for initiating each heartbeat by sending out electrical impulses that travel through the heart muscle, causing it to contract and pump blood. This process is what keeps the heart beating in a regular, coordinated manner.
Now, let's translate this explanation into Chinese:

Sinus arrhythmia refers to the normal increase in heart rate that occurs during inspiration (when you breathe in). This is a normal response and is more accentuated in children than adults. Sinus tachycardia refers to a fast heartbeat (tachycardia) because of rapid firing of the sinoatrial (sinus) node.
