Triathlon Training – Managing Arrhythmia Part 2

heart nodes - Triathlon Training - Managing Arrhythmia Part 2Today is an extremely sad day for me…

My waking HR is still all over the place for the last 3 days now – 32bpm to 119bpm. Further research indicates that the drug Verapamil may not always be the way to go in treating arrhythmia, and in fact in the long term may even worsen the condition and increase the likelihood of sudden cardiac death!

I stopped taking the medication and re-evaluated the situation.

My heart specialist also indicated that one or two months of “de-training” may well sort out much of my ventricular bigeminy (low HR).

I feel this should now be my first course of action.

I also have SVT (Supraventricular Tachycardia) causing in my case fast HRs up to 240bpm (or more), and the only alternative other than the unacceptable drugs would require heart surgery involving cryoablation (freezing) of heart tissue around the SA / AV nodes that are responsible for the extra signals and high heart rates.

I feel this should be my second course of action (medical aid permitting).

As today is the last day for 70.3 late registrations, I decided that it would be very unwise for me to continue with training for this and IM 2010 until my heart conditions have been properly sorted out.

So basically that’s it for now. I will be spending the next two months trying to get a lot of rest and doing  only light short duration stuff (not more than once a day), and a lot of that mainly Pilates and Yoga. During this time I will also see to getting the surgery done if and when possible.

There is still 2011…

Triathlon Training – Managing Arrhythmia

Arrhythmic heart rates have plagued me all week, causing me much concern and lost training.

Went for a scheduled 16km run after doing marshaling duty for the ECTA tri development race on Sunday.  Cruised comfortable with HR at 124bpm for 7km before a sudden increase up 240bpm and feeling light headed.

I Walked 500m to settle things down, then started running again and felt something “click” right with a surge of strength and energy and return to normal HR. Nevertheless I decided to cut the long run short after 10km.

So yesterday (Monday 23/11) I went back to my doctor to discuss the whole issue and re-evaluate the specialists report of the examination I had done before going to the WTC in Australia.

The report definitely found no reason for me to discontinue high intensity sport, so the doctor prescribed a very low dose of Verapamil (Verahexal 240 – half tab daily) which is used to manage certain arrhythmia conditions such as mine.

Of interest, it was my own internet research that lead me to this drug recommended by a sports cardiologist:-

Maybe it was just in the head,  but I felt almost immediate relief with palpitations and HR fluctuations subsiding. Swim session yesterday evening also felt much better and waking HR was a steady 54bpm this morning. As I type now it is sitting comfortably between 50 – 55bpm.

Took an easy 40km ride to Schoenies (with drills) this morning in strong easterly (hey, this wind just doesn’t want to let up!). Time was rather slow with legs feeling quite lethargic (perhaps due to no riding and lots of sitting last week) and I actually battled to get my heart rate up to 124bpm (70%). This of course may also be the effect of the drug…

I have been delaying my registration for the 70.3 being unsure of my injury/arrhythmia/progress allowing me to be ready in time. Friday 27 November is the last day for late registrations, so it is decision time soon. I am still not confident and will need the next 3 days to see how things go….
