3 vs 2 leads

third lead implantation.

I also have mild heart failure,also 45% ef. That means that my heart pumping volume has diminished 17 % because a normal heart pumping volume is 54 %. I am cycling a lot and my average speed is reduced by 10% and I have less power. I cannot ascend a hill steeper than 10 %. I get fatigue legs at low heartrate. My average heartrate during cycling is 109 bpm. At higher heartrates my legs are painfull.

My question to you is:

Do you have more power during exercise after you third lead implant? Are you feeling better? Has your heart failure dimished now and by what percentage?

Greetings,

Hans

What you are talking about (3 lead device) is called a CRT, Cardiac Resynchronization Therapy, originally known as a Bi-Ventricular device. The intent is to pace both ventricles in synch to allow a stronger ejection and increase your output. These devices are over used and in fact a study shows at least 40% of patients receiving a CRT will not benefit and may even do worse.

The ideal candidate for a CRT device is the individual with moderate to severe, symptomatic CHF with medical therapy (class III–IV) If your EF is above 35% you are not in this category

Cardiomyopathy (weakened and enlarged heart muscle)

Significant electrical delay across the lower pumping chambers (bundle branch block) BBB with a QRS delay of greater than 150ms

Some CHF patients who are candidates for CRT are at also high risk of dying suddenly from Ventricular Fibrillation. For these patients, a special CRT - D device is available that can stop potentially life-threatening rapid heartbeats by delivering an electrical shock known as defibrillation.

The response to CRT varies greatly between patients. Though improvements may be noticed almost immediately in some patients, they may not be fully realized for weeks or months in others.

I have ClassIV Stage D or end stage heart failure with an EF of 15%  and LBBB with a QRS of greater than 200 ms but do not benefit from CRT therapy due to moderate stenosis of the Mitral Valve, so even when you meet all the criteria, there's no guarantee you will benefit.

Don't get discouraged, you coukld be one of those who benefit, but don't assume improvement is a guarantee. OIn fact EP's often oversell the benefits to patients

I do feel better and have experienced less shortness of breath

Thanks for your comments. Last week I went for an echo in hospital and next month I hear the results from my cardiologist. I am anxious to hear what he has to say.
