Hung

Hi all
my name is Hung le, and I have a 3 year old son, who have a dilated heart. Rcently I have him implant a CRT. At the second check up, his doctor has increase dual chamber biventricular pacing AV interval to 100ms from 60ms. After that, it seems that he is quite more often tired and short breath. Should I wait for a next check up or keep on monitor and have it set back to what it was. Cuold anyone please tell me what is the "100ms fo AV interval would be different from the 6oms AV interval. Thank you all

Der Smitty
thank you so much for your info. You seem to have lots of knowledge on this matter. My son has been diagnosed with Dilated Cardio Myopathy, when he was two and a half year, since then I have brought him to see so many doctors, and finally, one has told me to implant a CRT for him which will help his heart resychornized since his left bundle branche is blocked, and I did. However, I wonder if there is any way to cure his illness. I wouldn't went broke to save him

Hi Hung le,

Don't let what I write fool you about my knowledge of heart problems. I really know very little but since I have the time I like to look up what I think may be answers to questions I see here and pass them on.

If you would like some information on your son's illness I suggest that you go to Google and put in "dilated cardiomyopathy prognosis." From what I can see there are no medicines that will cure his DCM, but with medications and the CRT he can have a normal life.

Good luck to your son and you,

Smitty

AV Interval

Hello Hung le,

Let me go back to the beginning on this so if I'm wrong you will at least know where I'm wrong.

As you know, the atrium receives blood from the lungs, contracts and passes this blood on to the ventricle where it is pumped out into the body. After the pumping of the blood from the ventricle the cycle starts all over but the atrium must have time to transfer the blood to the ventricle. The time required for the blood transfer is measured in milliseconds (ms).

If I understand all this your son initially had a delay of 60ms programmed into his CRT and that was changed to 100ms. With the extended delay he is now often SOB and tired.

Therefore, I would suggest you discuss the difference you see in him with his Dr.

I wish your on the best,

Smitty
