Dizziness is one of the most common health concerns. However, few cases of dizziness are due to serious conditions.
Shortness of breath can be frightening. Most of the time, a heart or lung condition is the cause.
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.

MRI uses a magnetic field and radio waves to create detailed images of the organs and tissues within your body.
Treatments and drugs
Coronary angioplasty and stents can reopen clogged heart arteries if buildup of plaques is causing chest pain, shortness of breath or a heart attack.
Implantable cardioverter-defibrillators (ICDs) can control abnormal, life-threatening heart rhythms and prevent cardiac arrest.
