New to this website.....

I have had 2 ablations and 2 epicardial ablations for V-T. I currently have a pacemaker that paces my heart at a minimum of 70 beats per minute and I am taking 25mg of Metropolol twice a day and 160mg of sotolol twice a day. The theory is that the pacemaker will not allow my heart to beat slow which causes the V-T and the beta blockers will control the arrhythmia. During the last epicardial ablation the cardiologist found that the area causing the V-T was next to the phrentic nerve and could not be abated.

If the above treatment doesn't control the V-T, the cardiologist said the next step would be a Cardio Sympathectomy.

Has anyone had this procedure, does it work, any information is much appreciated.

Thanks

Hi CaptainKirk, welcome to HealingWell.

Although I was not previously familiar with this procedure, I did spend a little time reading about it. Interesting concept. The procedure itself doesn't seem difficult, or especially problematic, and the results were impressive on a small number of patients receiving it. The articles I skimmed through were for patients with defribrillators and the reduction in events triggering same.

I searched for Cardiac Sympathetic Denervation (enervation is to supply with nerve input, denervation is to remove that nerve connection).

We've discussed (in this forum) an aspect of heart rhythm disturbances that involve the Gastro-Intestinal Tract. One authoritative article that I read, (but clearly didn't fully understand, I'm not a doctor) discussed the involvement of the sympathetic and parasympathetic nervous systems. The Sympathetic increases heart rate, say in response to Fight or Flight emotions. The Parasympathetic slows the heart after a Fight or Flight response.

The article: Cardiac manifestations and sequelae of gastrointestinal disorders

bjcardio.co.uk/2009/07/cardiac-manifestations-and-sequelae-of-gastrointestinal-disorders/

"A more commonly accepted view is that the initiating mechanism is a neural reflex resulting from autonomic stimulation. It has been shown that in some patients, increases in vagal tone can paradoxically cause tachycardias. It is therefore plausible that a parasympathetically-mediated mechanism is involved in all deglutition arrhythmias; causing bradycardias in some, and tachycardias in others. Despite this, it appears that in some patients the parasympathetic nervous system is involved, whereas in others, activation of the sympathetic nervous system is causative. One particular study describes three distinct autonomic reflexes resulting in deglutition tachyarrhythmias; while the arrhythmia was abolished by atropine and potentiated by cholinergic agonists and propranolol in one patient studied, the reverse was found to be true in another. In another patient, administration of both atropine and propranolol was necessary to abolish the arrhythmia produced on swallowing – suggesting roles for both the parasympathetic and sympathetic nervous systems."

Please note, I am not advocating that your problem is caused by digestive issues, but I am suggesting that consideration be given to the above paragraph. In my limited knowledge, it is evident that some of the GI Tract induced arrhythmias that the Sympathetic system is active in some, the Parasympathetic system active in others, and incredibly in limited cases, they both seem to have some involvement. This assessment was made, in the above paragraph, by the suppression of these systems using pharmacological means. Ask your doctor if the Sympathetic Denervation will leave the Parasympathetic System dominant, and if so, is there any chance that may be an issue in your case?
