Greetings! Thank you for your question and welcome to HCM. I carefully read your query.
No, it is not true that you do not have
sick sinus syndrome any more. It is precisely as your first had information about this condition and the pacemaker
implantation. Sick sinus syndrome (SSS) is an entity where bouts of high and low heart rates happen. These high and low heart rates can also be accompanied by
arrhythmia or by regular heart rate.
Now, the strategy of treatment in this kind of condition, is to control both types of episodes: with high heart rate and with low one. Since the natural pacemaker of the heart - sinus node - is "sick", pharmacologically attacking the episodes with high heart rate, poses the heart to a greater risk of "stopping to beat". Therefore, a pacemaker is implanted, which works every time the heart beat goes under a certain rate when pacemaker is programmed to spike and generate electrical impulse (for example, 60 or 70 beats per minute). It is only then when pharmacological agents to slow the heart rate down or prevent bouts of high heart rate (e.g. beta-blockers,
verapamil and
diltiazem,
digoxin, antiarrhythmics) can be installed to the treatment strategy. Thus, you have treated or protected sick sinus syndrome.
I hope I was helpful with my answer.
Kind regards,
