Bradycardia is a condition characterized by a slower than normal heart rate. While a normal adult heart beats between 60 and ...

Sick Sinus Syndrome This type of bradycardia causes an abnormal heart rhythm. You may have irregular heartbeats or ones that flip between slow and fast. This syndrome is not as common.

Sick sinus syndrome can cause bradycardia, tachycardia (a fast heart rate) or a mixture of the two, referred to as brady–tachy syndrome.

Answer : So, with sinus bradycardia, the heart rhythm is coming from the normal pacemaker, the sinus node, and the rate is slow. So, bradycardia is defined whenever the heart rate is 60 beats per ...

A causal relationship between COVID-19 treatment with remdesivir and sinus bradycardia is 'at least a reasonable possibility,' the EMA's safety committee has concluded.

We found that sinus bradycardia in members of a large family was associated with a mutation in the gene coding for the pacemaker HCN4 ion channel. Pacemaker channels of the sinoatrial node generate ...

When bradycardia occurs with these symptoms it is called symptomatic bradycardia. Common causes of symptomatic bradycardia are sick sinus syndrome and atrioventricular block, or a combination of the ...

Endurance athletes often experience sinus bradycardia, a slow heartbeat. A new paper shows this effect may be due to changes in the “funny channel” of the sinoatrial node.

Because his bradycardia persisted after his potassium levels were corrected and he had received epinephrine, "we decided on temporary use of a transvenous pacemaker," they explained.

Two mechanisms may underlie cyclosporine-associated bradycardia. Cyclosporine may suppress automaticity of the sinus node. Sinus arrest has been reported in patients given cyclosporine. 4 An ...

Italian researchers screening a large family have found a mutation in a gene coding for a cardiac pacemaker channel that is associated with bradycardia. And it's likely that different mutations of ...
