Do you think these changes in settings have made a difference?

I got some reports today from my EP and wanted to post to see if any of you thought the changed they have made could be contributing to my vertigo. First of all on my EKG report it says: LVH w/ IVCD. This is the first I've heard of the IVCD. Not even sure what it is. Here are the settings for 6-2007:
Right Ven. Lead Right Atrial Lead
Polarity: bipolar Polarity: bipolar
Threshold: 5.00V/0.30ms Threshold: 5.00V/0.20ms
Impedance: 888 ohms Impedance: 448 ohms
Amplitude: 9.8 mV Ampitude: 1.2 mV

% paced A: 97% and V: 37 %

Final Reprogramming:
Mode DDI
Atrium: 5V/ 0.8ms sense: 0.3mV
Ventrical: 5V/0.6ms sense: 0.3 mV

Settings in 10-2008
Right Ven. Lead Right Atrial Lead
Polarity: bipolar Polarity: bipolar
Threshold: 5.00V/0.10ms Threshold: 5.00V/0.03ms
Impedance: 360 ohms Impedance: 472 ohms
Amplitude: 8.6 mV Ampitude: 2.1 mV

% paced A: 91% and V: 0%

Final Reprogramming:
Mode DDI
Atrium: 5V/ 0.5ms sense: 0.3mV
Ventrical: 5V/0.5ms sense: 0.3 mV

Thanks for any thoughts or advice! I have no idea what any of this means!!

Heather,

I expect that only an EP will explain these changes to you and what the mean. I would not expect any changes in your AICD settings would result in vertigo. The IVCD stands for Intra Ventricular Conduction Delay, which happens with HCM.

The thing that stood out to me was the ventricles being paced/sensed 37% of the time to 0 % of the time. Did they turn that pacing/sensing off or am I just not needing to be paced in the ventricles? I know the ventricles are what pushes the oxygenated blood through the body.

Heather.

I would certainly ask the EP, but my hunch is that your pacer is set to pace only when needed. perhaps you no longer need pacing. In any case I would give the EP a call.
