The electrocardiogram during the onboarding physical examination is not very normal

The abnormal electrocardiogram found during the onboarding physical examination may be related to physiological factors or heart disease. Common causes include sinus arrhythmia, myocardial ischemia, arrhythmia, etc. Suggest further examination to clarify the diagnosis.

1. Sinus arrhythmia

Sinus arrhythmia is often related to breathing, emotional tension, or fatigue, and belongs to physiological changes. The electrocardiogram shows alternating fast and slow heart rate, with no specific pathological significance. It can be improved by adjusting breathing rhythm and maintaining emotional stability, and generally does not require treatment. If accompanied by palpitations, traditional Chinese patent medicines and simple preparations such as Wenxin Granules or Shensong Yangxin Capsules can be used for conditioning according to the doctor's advice.

2. Myocardial ischemia

Myocardial ischemia may be related to insufficient coronary artery blood supply, as evidenced by ST segment depression or T wave inversion on electrocardiogram. Long term hypertension and hyperlipidemia are common causes, and patients may experience chest tightness and shortness of breath. Coronary CTA or exercise stress test should be improved to confirm the diagnosis. Treatment can use drugs such as sustained-release isosorbide mononitrate tablets and compound Danshen dripping pills to improve circulation.

3. Arrhythmia

Premature beats, atrial fibrillation, and other arrhythmias can be manifested as abnormal QRS waveform or irregular rhythm on the electrocardiogram. It may be related to electrolyte disorders, hyperthyroidism and other diseases, and some patients may experience palpitations and fatigue symptoms. Severity needs to be assessed through dynamic electrocardiogram, and if necessary, propafenone hydrochloride tablets or metoprolol tartrate tablets should be used to control heart rhythm.

4. Electrolyte imbalance

Hypokalemia and hypomagnesemia can lead to increased U-wave or prolonged QT interval on electrocardiogram. Commonly seen after diarrhea and diuretic use, it may be accompanied by muscle weakness symptoms. Blood electrolyte levels need to be tested, and mild imbalances can be corrected by taking potassium chloride sustained-release tablets or potassium magnesium aspartate tablets orally.

5. Abnormal cardiac structure

Organic diseases such as hypertrophic cardiomyopathy and heart valve disease can cause increased electrocardiogram voltage or conduction block. Echocardiography is the diagnostic basis, and patients may experience difficulty breathing after physical activity. Targeted treatment such as sustained-release capsules of diltiazem hydrochloride or spironolactone tablets should be selected based on the cause of the disease. After discovering abnormal electrocardiograms, one should avoid vigorous exercise and emotional excitement, and ensure 7-8 hours of sleep per day. Pay attention to low salt and low-fat diet, and supplement with foods rich in potassium and magnesium such as bananas and spinach in moderation. It is recommended to have a follow-up electrocardiogram within 1-3 months. If symptoms such as persistent chest pain and fainting occur, seek medical attention immediately. Workplace personnel should get up and move around every hour when working at a desk for a long time to prevent changes in electrocardiogram caused by autonomic nervous system dysfunction.
