Introduction

Sinus rhythm refers to a normal heart rhythm generated by the sinoatrial node as the pacemaker. Left ventricular high voltage indicates increased amplitude of the electrical signals from the left ventricle on an electrocardiogram (ECG), which may be caused by conditions such as left ventricular hypertrophy or hypertension. Sinus rhythm with left ventricular high voltage means that, on the basis of a normal sinus rhythm, the ECG shows increased amplitude of the left ventricular electrical activity.

Sinus rhythm with left ventricular high voltage refers to an electrocardiographic finding in which the amplitude of electrical potentials from the left ventricle is increased, on the basis of a normal sinus rhythm. The details are as follows:

Sinus rhythm indicates a normal heart rhythm originating from the sinoatrial node. Left ventricular high voltage refers to increased amplitude of the left ventricular electrical signals on the electrocardiogram (ECG), which may result from conditions such as left ventricular hypertrophy or hypertension. Sinus rhythm with left ventricular high voltage means that, against a background of normal sinus rhythm, the ECG shows heightened electrical activity from the left ventricle. This finding may indicate the presence of heart disease or other underlying cardiovascular problems. The most common causes of left ventricular high voltage are left ventricular hypertrophy and hypertension. Other possible causes include aortic stenosis, aortic regurgitation, and valvular heart diseases. When sinus rhythm with left ventricular high voltage is observed in young individuals, genetic heart diseases should be considered and further evaluated.

It should be noted that sinus rhythm with left ventricular high voltage is not a definitive diagnosis but rather an ECG indicator suggesting possible cardiovascular abnormalities. If this finding is present, it is advisable to consult a physician promptly and undergo further evaluation and appropriate management.

What is sinus rhythm?

In general, sinus rhythm refers to a normal heart rhythm in which the electrical activity of the heart originates from the sinoatrial node. The sinoatrial node is the heart's natural pacemaker, located at the junction of the right atrium and the superior vena cava. Its automatic cells can spontaneously generate regular electrical impulses that travel through the cardiac conduction system, sequentially exciting the atria and ventricles, thereby maintaining the heart's normal contractile and relaxation rhythm.

What causes dizziness, blacking out, and fainting when standing up from a squat? What should I do?

Arrhythmia, an abnormal heart rhythm caused by disordered electrical activity in the heart, reduces cardiac output. This insufficiency worsens during postural changes such as squatting to standing, leading to inadequate cerebral blood supply and resulting in dizziness or fainting. Symptoms often include palpitations, chest tightness, and shortness of breath; severe cases may be life-threatening. Treatment, under medical supervision, includes antiarrhythmic medications such as propafenone hydrochloride tablets, metoprolol tartrate sustained-release tablets, and amiodarone tablets to restore normal heart rhythm.

What does sinus tachycardia mean?

In general, sinus tachycardia refers to a heart rhythm disorder characterized by a heart rate exceeding the normal range under the control of the sinoatrial node. Whether special treatment or intervention is required depends on the underlying cause and specific circumstances. If discomfort occurs, prompt medical attention is recommended. After the occurrence of sinus tachycardia, it is necessary to first rule out whether it is caused by physiological factors. If episodes remain frequent even after removing the triggering factors, further evaluation is warranted.

Is fennel good for heart health?

In general, fennel has certain auxiliary benefits for heart health, but its effects are limited, and it should be consumed in moderation. Fennel is rich in dietary fiber, vitamin C, and potassium. Potassium helps maintain normal heart rhythm and stable blood pressure, benefiting cardiovascular function; dietary fiber promotes intestinal motility and helps regulate blood lipid levels.
