Question: HI there.

Yesterday, I had heart palputations. I can describe it as a thumping - a bit like the sensation when a lift stops abruptly. I have had this occasionally for a year or two and have had the ECG and Holter tests, but neither recorded anything significant. Last night however a new sensation - quivering, either the heart pumpins so fast as to be not effective or a weird sort of spasm. This lasted for about 10 secs then the heart would go back to normal for about 40 secs, then again. This went on for about 30 mins. During the quivering my pulse stopped (I was taking my pulse at my neck. I also felt hot. Earlier in the day when the thumping sensation was at it's worst I felt dizzy and hot.
This morning I have woken up and my heart feels like it has run a half marathon (feels like a faint muscle strain) Other than that I have no real complaints.

What should I do next - I guess make an appointment at my GP

Welcome to XXXXXXX forum.
Presence of palpitations along with absence of neck pulse definitely indicates some sort of effect on heart.
Palpitations may be due to heart disease or due to hormonal disorders.
As your ECG & holter monitoring was normal, there is least chances of heart disease causing palpitations.
Hormonal diseases could be hyperthyroidism, pheochromcytoma and cushing's disease.
All these hormonal disorders are associated with pulsatile secretions of hormone with palpitation like feelings.
Felling of hot sensation also suggest the same diagnosis.
Do you have some sort of stress?

You should consult with XXXXXXX medicine specialist/ cardiologist and should go for thorough check up.
You should also go for relevant investigations such as thyroid profile, ACTH level, adrenaline & noradrenaline level along with vaniyl mandelic acid.
You should also go for electro-physiological study of your heart also. At time aberrant pathways are present in heart as anatomical variation and may cause thumping feeling.
Hope that helps.
Let me know if I can address any more concerns.
Take care,
Dr. Mayank Bhargava

Help! Easy Question (I think)

I just did an ACTH stimulation test with 250 mcg Cortrosyn one time IV and blood drawn baselne, 30, 60. Now I need to do a Low Dose Dexamethasone Suppression Test. How long do I wait from the ACTH stim. to when I take the Dex at 11 at night (& then do the blood test the next morning). In other words, not only considering the 1/2 life & full elimination of the Cortrosyn, but what is the 1/2 life & full elimination of my natural Cortisol that probably got elevated from the Cortrsyn? I want that to be all normalized when I do the Low Dose Dex Suppr. Test.
