Heart disease, usually thought of as blockages in the arteries that can cause a heart attack, can describe any medical condition affecting your heart.
Tachycardia, a rapid heart rate, is caused by an abnormality in your heart's electrical impulses. Tachycardia can cause serious complications, including sudden cardiac arrest.
Tests and diagnosis
MRI uses a magnetic field and radio waves to create detailed images of the organs and tissues within your body.
