CRT

Has anyone out there had a CRT-D and had it downgraded to just a CRT. If so how did the doc determined you didn't need a CRT-D?

CRT

There are two models of CRT, the - D (defibrillator) and - P (pacemaker) The only difference between them is that the -P does not have defibrillation and ATP capability. So there really is no reason to "down grade" since all they would have to do with your device is switch off the defibrillation function.

Could cost be a factor as defibrillation does not come for free .

In fact a CRT-D is considerably more expensive than one without the D . The difference is shocking !

I assume you only need the defibrillation function if various tests ECGs etc show that you have a history of ventricular arrhythmias and tachycardias especially if these have ever caused a sudden cardiac arrest.

ICD guide lines

by BillH - 2016-01-22 03:01:01

There are several guidelines that indicate the need for ICD. One of which is low EF (ejection fractions).

One of the reasons for the CRT feature is when ventricles are not in sync. And if that causes a low EF there might also be the need for ICD features.

If the CRT is able to increase the EF then ICD function might be turned off. Or if a replacement is needed the CRT-D might be replaced with a CRT-P

You know you're wired when...

The meaning of personal computer is taken a step further.

I am no expert, but I believe that without the defibrillator that I have, I would be dead.
