Hi all. First of all I want to clarify I do know that diagnosing cannot and should not be done over the internet, however I have been having a lot of troubles with my heart lately and it's really scaring me, and I won't deny my anxiety over the situation may be making it a lot worse than it really is. I'm just trying to find some sort of ideas on what is wrong with me, I will try to keep this as simple as possible.

I am a 19 y.o. female previously diagnosed with PCOS (Poly Cystic Ovarian Syndrome) and depression, but otherwise has always been completely healthy.

The Tachychardia pops out of nowhere. My heart starts beating faster and faster and I cannot get it to stop. No chest pain, no shortness of breath. The only symptom regarding my heart is the Tachychardia.

First attack was Sunday the 8th after Midnight, I was at the gym and noticed (via treadmill's heart monitor) that my heart spiked 230. Usually average 150-170. I was only walking on a slight incline, working myself less hard than I usually do. I stopped walking and everything was fine after that. Went on the exercise bike and my heart rate stayed at 170 or so and I was fine.

Second attack was later that morning. I pulled an all-nighter, it was finals week and I had 3 papers due in 48 hours. No caffeine involved at all. I set my alarm for 10am and went to bed around 930, the plan was to just rest for a bit and then get back up and finish my assignments. As soon as the alarm went off my heart went out of control. Roommate called 911. Went to the ER and had two EKGs, a chest x-ray, urinalysis and blood work. Everything came back normal, diagnosis was sinus tachychardia and the doctor said "It just happens sometimes, and we don't know why." Told me to try coughing vigorously or bending over and straining as if going to the bathroom to knock my heart back into rhythm.

Third and fourth attacks were minor and happened, again, after short naps with my alarm going off. They were stopped by straining/coughing.

Fifth attack was on Tuesday the 10th when I was meant to go home for the Holidays. Laid down for a nap and my alarm set my heart off again. Had really intense tingling before it happened which alerted me my heart was about to speed up. Couldn't stop shaking either, so my friends called 911 and I went to the ER again. Another EKG, more blood work, everything was fine and this time I was told it was a panic attack. Had a sixth attack during this visit to the ER after I had fallen asleep in the hospital bed and woke up after a few moments. No alarm this time.

Seventh and eight attacks happened at home and were stopped with the strain and cough method. I was not sleeping or lying down when they happened, I was sitting upright.

Followed up with my physician on Friday the 13th and she referred me to a cardiologist for a Holter monitor. I also requested to have my Thyroid tested as I have had chronic fatigue and trouble losing weight previously, and my father's nurse wanted me to get it checked now that I am having heart problems.

During all of this I have also developed the following symptoms: chronic dry cough, tight throat, tight and sore chest. My throat and chest are especially tight after I have had an incident of Tachychardia.

I was fine for a few days but then my ninth attack was very bad and sent me to the E.R again. The tingling I had before this incident was specifically in my left arm/left side of body. I had called 911, calmed my heart down and asked not to go to the E.R. but after the medics left my heart started up again and so I asked mother to take me to the hospital. Calmed it down but it riled up again in the car on the way over there. A chest x-ray, an EKG, more blood work, and a urinalysis. Everything was normal except urinalysis, ER doc said I had a high white blood cell count indicative of a UTI. However, because I told him I did not have any UTI symptoms, he said "Then I won't treat you for something you aren't having symptoms for" and discharged me. Diagnosis here was palpitations/supraventricular tachychardia.

The next day I ended up contracting UTI symptoms. Pain/discomfort in the left side of groin and general urethral area, urine is dark and cloudy. No troubles urinating whatsoever, however, and there is no burning sensation anywhere.

Got fitted for the Holter monitor today and I am wearing it as I type this. Have an appointment with a cardiologist on Friday. I currently have a very tight chest and throat, my throat is a little sore, and I still have the chronic cough.

I am not on any medications currently. I was on Prozac for depression but was given the O.K. to stop taking it when I started going to the gym and had told my therapist I no longer felt like I needed it. I was also on Yazmin (birth control pill) for the PCOS but ran out of refills. I was given a new birth control called Necon with a higher dose of estrogen about a week and a half before all these symptoms began, and I immediately stopped taking it after the second trip to the E.R.

I do drink a lot of caffeine but have since cut it out completely since the second trip to the E.R.

I have had a lot of difficulty losing weight in the past, I started going to the gym in August in hopes of losing weight as I am fairly overweight (4'11 and 164 lbs) but even with intense dieting and exercise I could not lose a single pound or inch off my waist. I counted calories and nearly starved myself for a week or so, cut out soda completely, and by November was at the gym for an hour a day, or at least every other day. I did not lose anything nor did I slim down even the slightest.

However, as of my first Tachychardia incident, I have lost 7 pounds. I weighed 164 at the gym on Sunday the 8th, day of my first attack. Then at the doctor's on Friday the 13th I weighed 160. Weighed myself at my psychiatrist's today, and I am now down to 157.

As far as stress is concerned, I thought maybe the stress from finals is what triggered this but after finals week had ended I was still having problems. I am home with my parents for the winter Holidays now, and admittedly I do not live in a comfortable environment here. Mother has mental and social disorders and father has Multiple Sclerosis. Both are emotionally abusive and mother is sometimes physically, but very minor when so.

I just want to know what is wrong with me. At this point, it's one thing after another. I am terrified and being robbed of sleep, I just don't feel good in general and I'm alone through a lot of this so it's making it scarier. Does anyone have a clue?

Seeing as you have been quite well looked after at the ER, I can only suggest having a test for sleep apnea.

You are getting a lot of good care. Granted, most people feel rapid heart beat/palpitations at times, and they prove to be 'nothing' no matter how much testing is done, so doctors don't get too concerned too quickly.
You don't say how much Prozac you were taking or when you went off it. Prozac has widely different effects on people, and I might give that some thought if you stopped it a short time ago, and stopped cold turkey. Add to that the birth control, which can also have varying effects on women, either one or both could be things you are highly reactive to. (The weight loss could be related to going off the b.c.)
Each of us is unique, and putting two different drugs into our bodies might mean nothing to 999 people but something to 1. Possibly something about you, that science hasn't studied or seen, just can't handle an anti-depressant and the hormones of b.c.
Another thing to consider is a check of all hormone levels, maybe some time later, after you are off everything for a while, and off caffeine in coffee and sodas.

I had been off the birth control for quite a while. It was over the summer that I ran out of refills and I didn't get new pills until The last week of November. Prozac I just started taking less and less because I was beginning to feel like I didn't need it anymore and then after I got the O.K. from my therapist I stopped bothering to take it all together. Unfortunately I can't tell you what dosage I was on because I don't remember.

Timeline still lacking - we don't know when you tapered down and stopped Prozac. Or how many years you took it, or in what dose.
Given the timeline of the new b.c. in late Nov and the onset of palpitations Dec 8, I would look deeply into the long form description of Necon for some of the rare side effects, even though you only took it for a couple of weeks.
That's just one thing - obviously you are going to have to look into more and more obscure areas if this continues. There's even plain old panic disorder, not improbable given the pressures you have been under at school.
(I took Prozac back in the late 80s, and it had a paradoxical effect on me. While taking it, I wanted to chop off the back of my head or smash it into a wall. I felt a bizarre pressure or something there. My sister took it for just a few weeks and it helped her a lot. Each person is different. And going off it isn't easy!)

I started Prozac in the spring and started skipping around with how often I was taking it in October. By Mid-November I was no longer on it at all. My mother had a bad experience with Prozac also but I had never had any side effects prior. Before Prozac I was on Zoloft, so I have been on some form of anti-depressant for 2 years now.

My best answer was, quite truthfully, have you ever been tested for sleep apnea. It may have been short, but well founded from past experience.

I've never been tested for sleep apnea, but the Tachychardia does not always happen while I'm sleeping either.

Sleep apnea sounds reasonable to me too... tickle, want to tell your experience? She seems reluctant.

Chronic sleep deprivation, whether we know we have it or not (many people feel they get a good nights sleep), leads to heart disease, high blood pressure and stroke. Correct terminology is sleep apnea where the heart actually stops while sleeping leading to heart damage over time.

Effects of sleep apnea make a profound difference to everyday functions, lower concentration level, lower motivation and slower reflexes. Many doctors are now having heart patients tested for sleep apnea which is a simple overnight monitoring system in a clinical atmosphere.

Well I have an appointment with a cardiologist today, I can ask about sleep apnea there.

Cardiologist does not think there is anything wrong with my heart or anything wrong with me at all; he said it is all stress related. But my EKG said "essentially normal, minor non-specific t-wave abnormality" and he didn't comment on it? He told me my EKG was perfect. So what's the t-wave abnormality, then?

Also, I'm having an issue with tingling all over my body now. Regarding the UTI, I had a urine culture done after they found blood, protein and high white blood cell count in my urine, but the culture came back and was normal. No UTI. So now the question is: why am I tingling all over, and why is there blood in my urine?

White blood cell count could mean a low grade infection, no UTI detected you stated; as for blood urine, there is always blood in urine in small amounts which can only be seen by testing. Why did you not ask the doctor these questions ?

As far as the tingling goes, he didn't comment on it. Regarding the UTI, it was the day after the doctor's visit that my urine culture test results came back and proved negative for UTI, so I wasn't able to ask him.

I'm now suffering from painless/crampless diarrhea; stools that are entirely liquid. Although I am wondering if this is a side effect to the anti-biotic I was put on for my bronchitis.

Isn't this the first time you mentioned that you are taking antibiotics and have bronchitis?
This is part of the frustration for us. We don't need to know every detail of what you did at the gym, but DO need a nice short but comprehensive LIST of your situation.
Plus, we could digress until the cows come home... I once had severe bronchitis for 10 months, took every new antibiotic under the sun, and discovered by chance that it was caused by an infection deep in my jaw from a crack in a tooth under a crown. Once the tooth was removed, I was fine in less than 3 days.

Ok, then here's your list.

I am having one episode of tachycardia every other day at the very least. Sometimes it's two to three episodes in one day several days in a row. Usually happens when waking up.

I was told I had possible UTI and bronchitis. I got put on antibiotics and then the UTI urine culture came back negative. I started having diarrhea. I then started seeing specks of blood in my diarrhea. I stopped taking the antibiotics yesterday. No blood in diarrhea at the moment.

I have been having issues with tingling all over. Arms, hands, feet, face. Everywhere. Comes and goes.

I have abdominal point tenderness in upper right quadrant. Very mild, but still there. Has been there for a couple days now.

Anything else you need to know I will tell. But those are the basic symptoms I'm having at this moment.
