What is sinoatrial block?

Sinus-atrial conduction block may be caused by overdose, endotracheal intubation, electrolyte imbalance, coronary atherosclerotic heart disease and other reasons.

1. When overdose

patients use large doses of digitalis, beta blockers and other drugs, it may cause the function of the sinus node to be inhibited, resulting in sinus-atrial conduction block.

2. Endotracheal intubation

patients may cause vagus nerve tension to increase, affecting the function of the sinus node, and further causing sinus-atrial conduction block.

3. Electrolyte imbalance

Large area burns, severe diarrhea can cause excessive loss of potassium in the patient's body, resulting in abnormal potassium levels, at this time will also appear sinus-atrial conduction block performance.

4. Coronary atherosclerotic heart disease

patients with coronary atherosclerotic heart disease, can lead to sinus node damage, abnormal cardiac conduction system, resulting in sinus-atrial conduction block.
