Asystole during Tilt Table

[kathgd]

During a Head Up Tilt Table test recently I experienced syncope and asystole for over 60 seconds.  It is my understanding that this is extremely rare (CPR and saline induced the recovery) and I was fitted with a pacemaker.  I'm not on any medications, and feel fine, however I am concerned that there should be further testing or followup.  I am an active 60 year old woman and the reason I had the HUT was because I had several previous sudden syncope with severe injuries- concussions, broken nose, head gash...  
Can I assume that during these that I also was experiencing asystole?  That I possibly could have died from my heart not starting again or due to injuries from falling?  My pacemaker is pacing 25-30% which seems to be mostly at night when I sleep.  Is that a lot? Also, how rare is a 60 second asystole during HUT? My 2 cardiologists seemed a bit shaken when I finally woke up.
Thanks.

Thanks for your reply.   I wish I was able to find out detailed medical information about why there would be such a dramatic cardiac event every time I fainted.  I now suspect prolonged asystole each time I passed out because I was unconscious for so long after falling.  If you know of any articles or studies regarding similar events, let me know.  Happy healthy New Year!

Hi, Understand your anxiety. Asystole is cardiac standstill with no cardiac output and no ventricular depolarization. And yes it can cause sudden death. It is very rare to find during HUT and you were lucky that your doctors were there. The prognosis in asystole depends on the etiology of the asystolic rhythm. Good luck.
