Information about Heart rhythm disorders

 Sick Sinus Syndrome

Sick sinus syndrome (SSS) is a relatively uncommon heart rhythm disorder. SSS is not a specific disease, but rather a group of signs or symptoms that indicate the sinus node, the heart’s natural pacemaker, is not functioning properly. A person with SSS may have a heart rhythm that is too slow (bradycardia), too fast (tachycardia), or one that alternates between the fast and slow (bradycardia-tachycardia).

Atrial Tachycardia


Atrial tachycardia is a supraventricular tachycardia (SVT) that does not require the atrioventricular (AV) junction, accessory pathways, or ventricular tissue for its initiation and maintenance. It occurs in persons with normal hearts and in those with structurally abnormal hearts, including individuals with congenital heart disease (particularly after surgery for repair or correction of congenital or valvular heart disease).



Inappropriate Sinus Tachycardia





 

Inappropriate Sinus Tachycardia (IST) is a condition in which an individual’s resting heart rate is abnormally high – greater than 100 beats per minute or rapidly accelerating to over 100 beats per minute without an identifiable cause; although small amounts of exercise, emotional or physical stress are triggering factors. An electrocardiogram (ECG) does not show any abnormalities as IST arises within the sinus node where the normal heart rhythm is generated. It is a relatively new disorder. Individuals with this condition can find themselves increasingly disabled and experiencing high levels of anxiety. IST is not a life threatening condition but it can be very debilitating. Where sinus tachycardia is identified it is important to rule out other treatable conditions before making the diagnosis of IST – it may be that there is a curable cause.

    Hi, Danielle. I am so glad I found your blog! It's a great feeling knowing I'm not alone. I was diagnosed with IST about a year ago. Mine isn't super bad (passing out or being hospitalized), but I do suffer from severe chest pain, difficulty breathing and dizziness, with a few other symptoms. They say I can't do an ablation because of the specific location mine is at, I'll end up with a pace maker because the ablation will for sure not work.... I pray one day there is a cure because it's the hardest thing to live with. I never expected it to be this painful, and life changing. Mine just started randomly last year, and some doctors say I'll grow out of it, and some say mine will get worse as time goes on. So i don't know...Medication works but gives me the worse side effects. Thank you for writing this blog. I talk about it some on my blog, but no one understands what IST is, so it's hard to explain to others. Look forward to reading more of your blog! (tried to find a way to message you this, but couldn't find a space.) Have a good day!

      Thanks for the message Brittanynicolexoxox yeah I felt like I was on my own when I first got diagnosed but its amazing how many people you come across with it there's a few support sites on facebook if you type it into the search button they might help and also have lots of other nice people who suffer from ist its a closed group so its all private and others on your facebook wont be able to see any of it, sometimes it helps just venting how you feel and speaking to people in the same boat with how you are feeling ,am sorry to hear that about the ablation, ist is so hard to treat my cardiologist has told me the same thing I would end up with a pacemaker and my last two ablations failed and its having to outweigh what's best living with it or risking the ablation. Yeah its horrible and difficult how much it changes your life but each day dealing with it gets a little easier and yeah the side effects of the medication are sometimes worse than the ist. I also got told sometimes it will just go away except mine has got worse over the years. Am so glad my blog has helped you and your enjoying reading it and your right no one understand I lost many friends who didn't believe me stopped asking me out places just because of it all but am so glad in a way this illness has made me realise who matters and the people who care about me and I am so greatful for that and even more happy the people it has made come into my life. Also arrhythmia Alliance has alot on ist and also a helpline number sometimes just advice or speaking about it can take a huge weight off your shoulders.

      Thank you again for reading my blog.

      Stay strong and always feel free to message me for a chat.

      Lots of Love and hugs to you.

    Hi, I am new to this I am hoping someone can shed some light. Essentially, I am a very active individual, run, gym etc. About 3 weeks ago I started getting extremely short of breath and feeling like my heart was going to pop out of my chest. I kept thinking I was having a pulmonary embolism every-time it would happen and literally ended up in the ER 4 days in a row. I have been on an event monitor now and my Cardiologist thinks it is IST, but I am really confused as my resting heart rate is really low, around 50-60, I just keep having these daily episodes of my heart rate going up to 170 and extreme shortness of breath. Does this sound like IST or is my Cardiologist wrong? I am begging someone to shed some light on this for me, as I am literally scared to do anything because I may have an episode.

    Thnx,

    Alissa

    Hi Alissa

    I am no expert but ist is when your heart is fast all the time, could you get a second opnion ? It can't hurt the only person who can really tell you is a cardioligist have they mentioned an ep study to you ? as that's a good way to find out what your hearts doing and help diagnose you many abnormal rhythms can be fixed,. Am sorry to hear all this yeah its scary I hope this helps feel free to send me an email if you ever need someone to talk to.

    love and hugs xxx

    I am sure you do not need any one to tell you that most of the fireworks are harmful if they have not been handled the right way. People who get injured while lighting the fireworks generally harm their head, face, fingers, eyes and hands. https://visualaidscentre.com/service/eyes-specialist-delhi/
