Strong Heart Palps

Hi,

I am 18 years old, female. I exercise. I weigh 117 pounds and am 5'4 tall.

I always had palpitations after I drank coffee or tea. But recently these palpitations doesn't leave me a second.
Then I started having dizziness/vertigo, which seems to have left me now.
I also have some chest/back pain, which could be caused by my stomach (reflux?)

These palpitations are not really fast, I don't think my heart rate ever goes above 100 (exercising doesn't count). But the thing is, beats are so strong that I can feel it everywhere. In fact, when I sit still, **my body slightly rocks** (I checked on my webcam if I was really rocking and - yes). I can see my pulse on my neck and I bet my heart is visible on my chest when I'm lying down too.

So I went to a cardiologist, had ECG, 24h Holter, Blood tests and colored doppler electrocardiography. The doctor only checked the results of them which were watched/seen by other people. (who probably does this as a job, they would be experienced right?)

Other than that, the doctor in my school, which is actually neurologist, told me I had heart murmurs. I had ECG again and he said ECG was normal.

I am confused. Why didn't the cardiologist told anything about it? The school doctor checked twice and it was there both times. What causes these murmurs?
Is it possible to miss some problem about valves on echo? Is it possible for me to have some serious thing like regurgitation? He said it was probably not really important but I am concerned.
I also have these skipped/extra beats more than before. It's like my heart is having a heart time.
Should I be concerned?

What causes such strong beats? or murmurs? Should I continue exercising?
Could my chest/back pain related to my heart or is it just my stomach?

Thank you in advance for answering my questions.

Hello and hope you are doing well.

It could be a flow murmur, which could be innocent or a leaky valve murmur. An ECHO will help detect leaky valves. Flow murmurs can occur with conditions like anemia, which can also cause tachycardia. If it a leaky valve murmur, there could be different clinical outcomes. If this is mild, it may not need any therapy now. As you have been investigated, discuss all the possibilities with your doctor and clear your doubts.

Hope this helped and do keep us posted.

Thank you for your answer.

I meant colored doppler "echo" back there,
I checked the echo result later and saw there were trivial tricuspid regurgitation. Does that make murmurs? I don't have anemia.
Is there a possibility to miss something important in echo?
Also, is cardiomopathy detectable with the tests I had?
The doctor seemed pretty sure when he said I was healthy but these things make me concerned.

Hello and hope you are doing well.

The trivial tricuspid regurgitation can cause a murmur to be auscultated. A trivial regurgitation may not need any therapy now. An ECHO studies the anatomical structure of the heart, the valves, the heart muscle, the pumping capacity, namely the ejection fraction. The ejection fraction is a useful measure of left ventricular performance. The normal range is 63-77% for males and 55-75% for females. It reflects the pumping capacity of the heart. And yes, cardiomyopathy can be detected by X rays and ECHO.
