Hyperdynamic Heart

Hi there,

I apologise in advance as I think that I may be posting and have posted this in the wrong forum.

I am 20 years old, 5' 7" and I have a BMI of 26 and over the past few months I have been experiencing palpitations and light headnedness along with more recently becoming tired more easily and I have also been experiencing some high left sided pain which sometimes occurs more at night. I have also had tachycardia often and I am on some Beta Blockers for this.

I had an ultrasound the other day and the cardiologist said that I have a Hyperdynamic Heart and he did not really go in to much else and he is waiting for the results of a 7 day heart monitor now.

I was wonder what can cuase this and if it is dangerous at all?

Any help would be much appreciated on this.

“Hyperdynamic heart syndrome” is basically a nondescript condition or diagnosis covering a broad spectrum of possibilities.

To say that a heart is hyperdynamic means that it is overactive — beating too hard, pumping too hard and circulating blood at too rapid a rate. The patient may feel palpitations, nervousness, excitement, edginess or shortness of breath. The whole system is revved up as if he or she has been running hard, yet the activity is internally generated.

Calling this overactivity a “syndrome,” however, is like saying that fever is a syndrome — it is merely a symptom, with a great many potential causes, ranging from the benign to the serious. Ideally, systematic evaluation can determine the underlying cause and lead to effective treatment.

The hyperdynamic heart could result from a bona fide physical condition such as anemia, elevated thyroid function or an abnormality in the heart itself. Alternatively, it may simply be a response to alcohol, stimulating drugs or excessive consumption of caffeine.

Sometimes, after doing a complete medical workup and an analysis of the patient’s eating and drinking habits, doctors can find no specific reason for the hyperdynamic state. In such cases we prescribe beta-blockers, such as atenolol, propranolol or metoprolol, which are usually quite effective in calming the heart down and improving the patient’s symptoms. If the specific cause is known, treatment is directed at it.


Hope this helps,

Jon
