What does it do?
"The heart becomes enlarged, or hypertrophic, due to intense cardiovascular workouts, creating an increase in stroke volume, an enlarged left ventricle (and right ventricle), and a decrease in resting pulse along with irregular rhythms. The wall of the left ventricle increases in size by about 15-20% of its normal capacity. There is no decrease of the diastolic function of the left ventricle. The patient may also experience an irregular heartbeat and a resting pulse rate between 40-70 beats per minute , also known as bradycardia."Read more about it here.
Nothing really, Im healthy and happy : ) I will however do a electrocardiography once or twice a year from now on, just to monitor any potential changes.
I will post the actual electrocardiography-print - by popular demand.
