Question: My chest was beating strangely and then I got really hot and sweating. I regularly have pac's, but this felt like a bunch for about 30 seconds, I hit my chest to make it stop. the feeling hot was new. should I be alarmed? I have had ekg, strees test and halter and they found no issues as of yet.

Brief Answer:
Other non-PAC's causes to look for...

Detailed Answer:
Hi there,

I am sorry for the situation you are in.

Apart PAC's, other possible causes to feeling hot and sweating that come to my mind are:

- hypoglycemic episodes (should monitor your blood glucose at the time you get the episode)
- thyroid hormones imbalance (should run thyroid function test)
- drops in blood pressure (hypotension) due to metoprolol use (monitor blood pressure when you have the episodes)
- hormonal changes due to monthly periods (flashes) or perimenopause syndrome

You can check them out with your doctor to determine the right cause!
All the best!

I have been told that pac's are not harmful, can you explain this to me. I do not understand how your heart beating wrong will not harm you in the long run.

Brief Answer:
Gives discomfort,but not harmful...

Detailed Answer:
Hi back,

Thank you for following up.

Yes, what they have been told you is right: PACs are not harmful, they give discomfort but at no harm.

PACs are premature atrial contractions, in other words, the atrium have a premature contraction, followed by a compensatory pause (you feel like your heart stopped beating or pause).

As the diastole takes too long, the next beat will be felt as palpitation (stronger).

In other words, you might feel flattering sensation near your heart; stronger heart beats or skipped heart beats and other symptoms (like sweating, high heart beats/min at resting, chest pain, difficulty breathing, etc.).

Once again, PACs is not going to cause any harm to you as long as no organic problem to the heart has been found.

There are other factors that cause PACs including:
- smoking
- using recreational drugs
- caffeine
- alcohol
- stress/anxiety

Avoid using them and try to control stress/anxiety, and won't feel PACs.

All the best!

Hello, recently I went to urgent care with chest pain and periodically needing to take a deep breath. I really thought I would be going in for stress . They did a CT scan and they said they found a small shadow that they believed was a small clot. They had me go th er where they had me stay over night, my vent scan came back with low probability, the sonos on my legs found no clots, I have since been home and chest pain comes and goes and I really only have to take a deep breath when I am getting more stressed over this. It has been 3 days and I am still waiting results on the d dimer. I have also spent a lot of money on a months worth of blood thinners for the posibility it could come back negative. I am also a perfectly health 31 yr old female, non smoker, active, good shape, only had a laproscopic appendectomy last month. I am just not sure where to go from here because I am doubting my drs now

How come when I cough , I feel like I have an itch? It s driving me crazy. I ve been sick for about 3 days now, and idk if it s a small cold or something serious. But this morning I woke up with it kinda hard to breath because I had a lot of mucus in my chest or wherever, so I had to cough to clear it up. Just wondering if the coughing and getting itching sensation is tied to any of that.

Hi, I am 23 years old student, weight 43kg, high 154sm. Since i went to college(3 years), i felt some palpitations, first after some activity, and then for no reason, even when i was just sitting. Last years i made some tests, ECG showed normal rhythm, but 125bpm, and the echo and TSH were normal. Sometimes, if I have some worries or sth, i feel like i can not fill myself with air, like sth stops me in taking a deep breath, so i think anxiety cause that all, but it's not normal for me that my heart rate is never below 100bpm. Also, i can feel the beating in abdominal aorta, and with my 43kg it's not difficult to notice it without touching. Just 10 minutes ago i had one of those episodes (mentioning that these 2 days i am i little tired), so i checked the blood presure, it was 130/80, which i think is another problem.
Any thoughts? Last year the doctor said it's all about emotions, but i can't stop to think about that, especially when i feel like today, like my heart is gonna fly away.
