Electrocardiogram examination is a relatively conventional examination item in the hospital, and it is also a basic examination item of physical examination. Many people get ecG reports, see some technical terms, and often wonder if there is something wrong with the heart, in fact, many abnormal reports do not have much clinical significance and do not need to be dealt with.
1. Sinus arrhythmia
Most sinus arrhythmias are respiratory sinus arrhythmias, which occur in children, young people and the elderly, and are less common in middle-aged people, which is a normal physiological phenomenon and does not require treatment. In addition, factors such as nervous tension and autonomic dysfunction can also cause sinus arrhythmias, which do not require treatment.
2. Left chamber high voltage
Left ventricular high voltage refers to RV5≥2.5 mV, RV5 +SV1≥ 3.5 mV in the chest lead on ECG. In a significant proportion of healthy people, the ECG will also show high voltage in the left ventricle. For young people without hypertension and abnormal cardiac color, the high voltage of the left ventricle of the ECG is mostly of no clinical significance.
3. EcG axis left or right offset
In general, people who are slightly fat are prone to the left side of the axis, while people who are emaciated are prone to the right side of the axis. In terms of age, the ECG axis of children is often biased to the right, and the ECG axis of the elderly is often deflected to the left. From the point of view of the heart in the chest cavity, when the heart part is to the right, the ECG axis may be biased to the right, and vice versa. Uncomplicated left or right deviation of the electrical axis is of no clinical significance.
4. Occasional early blogging
The number of premature beats per minute is less than 6 times for occasional premature beats, mostly physiological early beats, which are easy to appear in the case of strenuous exercise, excessive fatigue, staying up late, smoking and drinking, drinking too much coffee and strong tea, and emotional agitation. In the absence of any symptoms, occasional early episodes (whether atrial or ventricular premature beats) usually do not require medication.
5. Sinus bradycardia
Heart rate less than 60 beats / minute, called sinus bradycardia, bradycardia can be seen in athletes, people who insist on exercising for a long time, healthy young people, people engaged in physical labor, healthy adults sleep, although the heartbeat beats slowly, but there are no uncomfortable symptoms, these belong to physiological sinus bradycardia, a normal phenomenon, not cardiac lesions.
6. Non-specific T-wave abnormalities
If the usual physical fitness is very good, due to emotional tension, excessive pressure, overwork, poor sleep, etc., causing the ELECTROC T wave abnormality, and there are currently no symptoms of palpitation, chest tightness, chest pain and other uncomfortable symptoms, you can temporarily do not do any treatment, regular review can be.
7. Complete right bundle branch block
Complete right bundle branch block is due to the abnormality of the conduction system of the heart caused by the ecG performance, clinically no obvious clinical significance, 80% of the simple right bundle branch block occurs in normal healthy people, the heart's blood supply and cardiac function have no effect.
I-degree AV block
THE PR interval delay of atrial-ventricular conduction is indicated on the ECG, greater than 0.20 seconds. Once-atrioventricular block is a relatively common form of arrhythmia, most of which has no clinical symptoms and is often found during physical examination of the ELECTROCARDI. The current view is that a degree of AV block may be related to hyper-excitability of the vagus nerve, and is also seen in early manifestations of mild myocarditis, which generally does not require special treatment.
EcG examination is very important, and the following points should be paid attention to when doing ecG:
1. Do not drink, eat, eat cold drinks and smoke before the examination, and need to rest calmly for 20 minutes.
2. Sleep flat during the examination, relax the muscles of the whole body, breathe smoothly, keep quiet, and never talk or move the position.
3. If you have done an electrocardiogram in the past, you should give the previous report or record to the doctor. If you are taking digitalis, potassium salts, calcium, and antiarrhythmic drugs, you should tell your doctor.
