An EKG cannot evaluate the pumping efficiency of the left ventricle. An EKG is non-specific for diagnosing problems with the exception of conduction abnormalities and prior MI.
An EKG may suggest left atrial or ventricular enlargement, however such findings are non-specific, and may not be accurate.
Therefore, further work-up is indicated to access the left ventricular function. The most common test would be an Echocardiogram w/ bubble study, which measures the size of the heart chambers, along with the ejection fraction of the left ventricle. The bubble study tests for "shunting" (that is, a bridge in the septum between the right and left side of the heart)
Long-standing hypertension can lead to hypertrophy or dilation of the left ventricle. It is essential to maintain a normal blood pressure or to localize the source of the high blood pressure. Hypertension is defined as a blood pressure greater than 140/90.
In a 21-year-old, hypertension is an unusual finding, and is suggestive of a secondary source that is indirectly related to the heart. The more common sources are endocrine in nature, and involve the release of excessive amounts of hormones or corticosteroids. Another potential cause (which may be related to the pelvic pain) is renal artery stenosis.
I would ask your doctor(s) about being tested for the following conditions, all of which are associated with secondary hypertension:
-Renal Artery Stenosis
-Pheochromocytoma
-Cushing's Syndrome
-Aldosteronism
-Hyperthyroidism
-Hyperparathyroidism
Cardiac related causes would include:
-Marfans Syndrome
-Coarctation of the Aorta
-Hypertrophic Cardiomyopathy
-Dilated Cardiomyopathy
-Mitral Valve Stenosis
Should those prove to be within normal limits, the label of "essential hypertension" is made, and the hypertension is treated with drugs. Treatment is important, and prevents strain on the left ventricle, reducing the risk of future hypertrophy and dilation.
Long standing tachycardia (heart rate in excess of 100 bpm) may lead to Cardiomyopathy, and should be reduced with the aid of a cardio-selective beta-blocker (Atenolol 50 mg, qd or Metoprolol 50 mg, bid).
For combination tachycardia/hypertension, a beta-blocker combined with an ACE Inhibitor (Vasotec) or ARB (Diovan, Benicar, Micardis) would provide the greatest benefit.
I'm not sure why you posted to the anxiety forum, as your symptomatology is not suggestive of anxiety. I would start by seeing a cardiologist, and then an endocrinologist. I would not delay, as any change(s) that may have occurred to the heart may be partially or fully reversible.
You don't mention if you've had prior work-up(s), but the results from those would be helpful (if you have them).

I would seriously have a doctor check your thyroid counts. When my thyroid levels were off I was having heart palpitations, pelvic pain, and many other thyroid related symptoms. But, since my levels are back in range, I don't have any symptoms.
Please check into it. Feel free to e-mail me if you want to talk.
