Sinus rhythm, limb lead low voltage what is the meaning

Sinus rhythm refers to the normal release of impulses at the cardiac pacemaker in the sinoatrial node. Limb lead low voltage refers to a characteristic in ECG, indicating that the amplitude of ECG signals in the ECG of limb leads is relatively low.

Under normal circumstances, the pacemaker of the human heart is located in the sinoatrial node of the atrium, which will periodically release electrical impulses to make the heart contract. ECG is to detect ECG signals by placing lead electrodes in different parts of the body. Limb lead low voltage may be myocardial hypertrophy, resulting in blocked conduction of cardiac signals, thus showing the characteristics of limb lead low voltage in ECG.

It is recommended that patients with limb lead low voltage should consult a doctor for detailed evaluation and further examination in time, and formulate a corresponding treatment plan according to specific conditions.
