What could be the cause of Tachy-Brady Syndrome in someone with a healthy sinus node?

What could be the cause of Tachy-Brady Syndrome in someone with a healthy sinus node?

Mmm: to have tachy-Brady syndrome you need to have a sick sinus node so.. I don't think what you're saying makes much sense. If you have some ectopic tachycardia of some sort then you likely have a run of the mill SVT. Not tachy Brady. ...Read more

How risky are ablations of the sinus node?

How risky are ablations of the sinus node?

Depends.: All procedures have risks, some risks are more likely to happen with some procedures, and less with others. Sinus node ablation is safer than open heart surgery, for example, but is not risk free. Your doctor is required to explain what the risks are for the patient, and this depends on the condition of the patient at the time of the procedure as well. Ask the doc questions until you understand ...Read more

How have I lost 15 pounds over the past few months without trying? I'm now 120. Bloodwork is fine, but heart rate is often elevated from sinus node.

Need to be checked: If you have other symptoms - fever, cough, blood in your bowel movements, night sweats, a painless lump under your skin - you need further evaluation. You mention blood work is fine: you need a chest x-ray and thyroid tests also at a minimum. Are you exposed to any industrial toxins, fumes, or waste? Something is causing your weight loss. A careful evaluation is necessary to find it. ...Read more

Hi I have inappropriate sinus tachycardia and how do doctors know if its the sinus node or nervous system? Is that why some ablations don't work?

Hi I have inappropriate sinus tachycardia and how do doctors know if its the sinus node or nervous system? Is that why some ablations don't work?

Combination: Inappropriate sinus tachycardia (ist) is a difficult entity to treat with ablation. You want to be able to reduce the heart rate enough without leaving the person requiring a pacemaker. A newer medication ivabradine may be used off-label for ist. Good luck. ...Read more

What happens over a lifetime to a person with sinus node dysfunction and mitral valve prolapse?

Extremely variable: The two entities are usually unrelated. First, sinus node dysfunction. As people age, this usually becomes worse, and (especially if there is need for certain cardiac or BP meds), frequently causes dizziness, fatigue or fainting. Mitral valve prolapse can progress with more "stretching" of the valve over time, and hence becoming leaky, but it is a minority of people who develop significant leak. ...Read more
