What Causes Sinus Pain?

The electrocardiogram of sinus rhythm must meet the following two conditions: (1) P wave is upright on leads , , and aVF, and aVR is inverted. (2) The PR interval is 0.12 to 0.20 seconds. There is a special small nodule on the right atrium of the human body, which is composed of special cells called the sinoatrial node.

Usually due to

1.

The electrocardiogram showed sinusoidal P waves with a P wave rate below 60 times per minute and a PR interval greater than 0.12 seconds.

1. Sinus bradycardia, such as a heart rate of not less than 50 beats per minute, is asymptomatic and requires no treatment.

2. If the heart rate is below 40 beats per minute, and those who have symptoms can use heart rate increasing drugs (such as

1. Most patients disappear after the cause or cause has been eliminated.

2. Active treatment should be performed when there is a clear primary disease.

1. Sinus bradycardia has a heart rate of not less than 50 beats per minute.

2.

1. Cure: The heart rate increased to more than 60 times per minute, and the subjective symptoms disappeared.

2. Improvement: The heart rate improves to more than 50 times per minute, and the subjective symptoms improve.

3 Ineffective: There was no change in heart rate before and after treatment, and symptoms did not ease.
